  • Brewing tradition goes back to 736

    Hopland Germany

    Wherever beer is produced in the world it is the hops which give the beer its soul andwhich are responsible for the unmistakeablearoma, the characteristic bitter taste, forma-tion of froth and its keeping quality.

    Even the ancient Babylonians and Egyptiansheld hops in their wild form in high esteemas the aromatic additive for brewing beer.The German hop-growers look back on anover 1200- year hop-growing tradition. Originand beginning are not known with absolutecertainty. Presumably the hop culture inCentral Europe began between the 5th and 6thcentury. The oldest evidence for hop produc-tion in Germany can be traced back to theyear 736 A.D. In 860 A.D. hop yards werementioned in documents for Grndl nearNandlstadt/Hallertau.

    When the art of brewing began in monasteriesaround 1000 A.D. the quality of the beer im-proved. Monks cultivated the hops in themonastery gardens as remedies with calmingand styptic effects; presumably the monkswere the first to recognize the special signifi-cance hops had for the brewing process. Fromthen onwards monastery breweries and theadministrators of the royal courts devotedthemselves to its cultivation. With the devel-opment of the brewing trade and finallythrough the promulgation of the Purity Lawin 1516 which stipulated that hops are aningredient of beer, the hop production madea significant upswing.In the Middle Ages the focus was on North-ern Germany; an important brewing industrycame into being in the regions which belon-ged to the Hanseatic League. Hops weremerchandise for the Hansa towns. The firstbig hop-growing area in Southern Germanydeveloped around the town of Spalt.

    HoplandGermany

  • Quality was already an issue at an earlystage: In order to protect the reputation oftheir hops, certain towns were given the rightto seal the hops when marketing them: in1538 the Eichsttt Prince-Bishop awarded thefirst German hop seal to the town of Spalt;an example which all the hop communitiesof repute followed one after the other.In 1929 the Hop Provenance Law was passed.It stipulated that hop seals were a bindingcommitment for all German production re-gions, therefore establishing the outstandingreputation of German seal hops worldwide.

    Today German hops are grown in the produc-tion regions of Tettnang (Baden-Wurttemberg),Elbe-Saale (Thuringia, Saxony, Saxony-Anhalt),Baden-Bitburg (Rhineland-Palatinate) as wellas in Spalt and the Hallertau (Bavaria). TheHallertau is the largest single hop-growingregion in the world.Above all the naturally favourable climateand soil conditions contribute to the impor-tance of German hop production.

    Competence relating to commerce and processingOnly a third of the annual crop is used byGerman breweries. About two thirds are mar-keted worldwide.In the second half of the 19th century Germanhops were already being exported to the mostremote corners of the world.The central terminal was the hop market inNuremberg, which influenced hop pricesthroughout the world. With the start of therailway Nuremberg became a CentralEuropean railway junction. Know-how andbusiness intelligence accumulated here. Big,financially strong wholesale firms with far-reaching business connections organised thepurchasing, hop treatment, marketing andtransportation in 1858 there were 25 hopmerchants based in Nuremberg, in 1895 therewere as many as 364. About 30 big tradingfirms controlled the market and they compe-ted for nearly 95% of the turnover.

    Besides the traffic-related conditions techni-cal changes also played a part in hop preser-vation and storage. The hop merchants had toensure that the hops could be transportedover great distances by applying suitable pre-paration and packaging techniques withoutthe hops losing their aroma. In 1858 theNuremberg hop market was the first to bepermitted to sulphurize hops, which made itpossible to keep them for several years with-out considerable impairment in quality. Thispermission put the Nuremberg hop market agood step ahead of the other markets. In par-ticular the invention of the refrigerator by Carlvon Linde contributed to enabling hops to bestored over a longer period of time. Up until1900 Nuremberg remained the most impor-tant hop market in the world. At this time theGerman Reich accounted for 34.8% of thetotal hop acreage in the world, 28.1% of theworld production of hops was harvested here.

  • The spirit of beer Hops from Germany

    Up until the 1960s the brewers solely wantedcone hops to brew their beer. Nowadays lessthan 5% of the annual hop crop are used asnatural hops, more than 95% are processedinto pellets or extract hops in concentratedform and vacuum-packed. They take up lessstorage space and keep longer than conehops. The competence of German firms inrefining hops is unique in the whole world.

    Many of the important hop-trading and pro-cessing firms are resident in Germany. Theworldwide hop-trading firms with their hop-processing facilities and research laboratorieshave set up premises in the largest single pro-duction region in the world the Hallertau in order to be in direct contact with the hop-growers.In the Haus des Hopfens in Wolnzach, theonly service centre nationwide for the hop-growers (refer to Chapter Hop Service CentreWolnzach) there are the offices of the tradeassociations of the German hop-growers:German Hop Growers Assn., HallertauHop Ring, Hallertau Hop Growers Assn.,"Jura Producer Group for Quality Hops", aswell as the Hop Producer Cooperative andthe State Research Institute for Agriculture Hops Dept..And the leading scientific brewing and agra-rian institutions of the Technical University ofMunich-Weihenstephan in Freising as well asthe Hop Research Centre in Hll are not faraway.

    Successful researchWhen in 1926 the peronospora fungal diseasedestroyed almost the whole crop in theHallertau, the German brewing industry inHll near Wolnzach founded the Society forHop Research and the Hop Research Centre,among whose tasks it is to develop methodsfor controlling pests and developing modernproduction techniques.In addition the Hop Research Centre in Hllis well-known for its breeding successes.Up until the middle of the 20th century onlyone hop variety was grown in the productionregions the so-called traditional variety,which was named after the production region(Hallertauer, Hersbrucker, Spalter, Tettnanger).As the hop requirements for the brewerieshad increased by the end of the 1950 s, thehop acreage was expanded. As the pickingand drying facilities available at the time wereinadequate, the harvesting time had to beextended. So the Hop Research Centre alsodeveloped new varieties under the aspect ofdifferent harvesting times. In addition to this,the aim is to breed varieties which on the onehand meet the requirements of the hop-far-mers regarding pest- and disease-resistance,good production properties as well as highyields and on the other hand which possessthe outstanding brewing quality the brewingindustry requires. These are on the one handthe meanwhile world-famous aroma varieties,e.g. Perle, Hallertauer Tradition and Spalter

    Select, which combine extremely fine aromawith optimum production properties andparticularly resistance to various diseases. Incooperation with the hop-growers and hopmerchants the Hll hop-breeders have alsodeveloped the so-called high-alpha varietiessuch as Hallertauer Magnum and HallertauerTaurus and successfully launched them on themarket. These have a very high bitter contentof 12-17% alpha-acids, which give the beer itsbitter taste and stabilize the foam.

    The latest research work regarding the tanninxanthohumol, which is solely present in thelupulin glands of the hops, is also evidence ofGerman competence in the field of hops andbeer. In tests xanthohumol was seen to havea particularly wide variety of positive healthproperties. Initial in-vitro studies indicattedthat xanthohumol may have an anticarcino-genic effect and a grow-inhibiting effect oncertain turmour cells .

  • Hop Products

  • For a long time hops have been used ascone hops in brewing beer. At the sametime the hop dosage was always subjectto the natural quantitative fluctuations of the hop components.

    In the twentieth century with the begin-ning of the industrial manufacturing ofhop products in the 1960s, the breweriesincreasingly switched over to their use.The majority of the hops are processed intheir natural state to hop pellets or hopextracts which are dosed in wort boiling.

    Another part of the hops is processed toproducts with isomerised bitter acids or tohop-oil products (refer to family tree onright). Except in the brewhouse the latterare also added at later points during brewingsuch as e.g. during the filtration. This is whythey are listed under the generic termDownstream Products.

    Hop Products Family TreeDescription and explanation

    On the other hand the xanthohumol-enriched hop products are the logical consequence from the physiologically very promising research findings so far available on xanthohumol and other flavonoids.

    Today more than 95% of the hops world-wide are used in the form of products.Their advantage lies in better storage stability, their good homogeneity, greaterefficiency as well as their easier dosagecompared with cone hops.

  • Procedure steps in the production

    Hop Products

    Preparation:Arranging the hop lots ready for processing.

    Depositing:When deposited the hops are mixed fromthe various lots.

    Drying:Hops finally dried in a hop kiln.

    Cleaning:Separating foreign bodies, waste andmetal residues.

    Deep freezing:Leaf hops are deep-frozen at tempera-tures from approx. -30C up to -40C,by which the hop resin forfeits itsstickiness.

    Milling:Grinding the deep-frozen, brittle hops.

    Sieving:In several successive sieving steps thehop powder is separated into lupulinand bracteole fractions. In this way theconcentration of hop bitter compoundsis considerably increased. Grinding andsieving is carried out at temperaturesbelow -20C.

    Lupulin-enrichedhop pellets(type 45)

  • Lupulin-enriched (type 45) - Chart showing the production

    Standardising:At the customers wish the hop powder isgenerally set at a specific alpha-acid con-tent. This is possible by dosing the leaffraction to the bitter compound fraction,which analytically is monitored extremelyaccurately.

    Homogenising:The hop powder is thoroughly homoge-nised in the mixer and again checkedanalytically before pelletising.

    Pelletising:Compressing the hop powder into hop pellets in a pellet press.

    Cooling:Cooling the hop pellets directly after pelletising.

    Packaging:Filling the hop pellets into foil bags andcartons.

    Inspection:The processing is subject to official inspec-tion. The packed product is certified asrequired by law.

    Hop Products

    The spirit of beer Hops from Germany

    Hop pellets (type 90) contain the hop components in the same natural compo-sition as the cone hops. Due to processing the product is more homogeneousand due to packaging in a refrigerated state has good storage stability.

  • Procedure steps in the production

    Hop Products

    The hops are pelletised prior to making CO2hop extract. These hop pellets are filled intothe extraction vessels. Extraction is carriedout in a cyclic process.

    Starting the extraction:Liquid CO2 is brought to the required operating point (pressure, temperature) by means of a pump and a heat exchanger.

    Extraction:The CO2 flows through the hop pelletsand releases hop oils and resins from thehop pellets.

    Decrease in pressure:The pressure is reduced.

    Evaporation:In order to compensate for cooling causedby relieving pressure the CO2 is evaporatedin a heat exchanger.

    Separation:The hop extract is separated from thegaseous CO2.

    CO2-Extract

  • CO2-Extract - Chart showing the production

    Condensation:The CO2 is liquefied in a condenser.

    Cyclic process:The liquefied CO2 is recycled.

    Homogenising:The hop extract is homogenised in acollecting tank.

    Packaging:The pure hop extract obtained is usuallyfilled directly. At the customers wish it isfilled into drums or bulk packs which areused in automatic dosing units.

    Inspection:The processing is subject to official inspec-tion. The packed product is certified asrequired by law.

    The spirit of beer Hops from Germany

    With the appropriate pressure the CO2 works as a non-polar extraction agent.It dissolves the soft resins and essential oils from the lupulin in the hops. In arefrigerated state the natural pure resin extracts obtained have very good storagestability.

  • Procedure steps in the production

    Hop Products

    Extraction:The coarsely milled leaf hops with thewaste and metal residues removed aremixed with ethyl alcohol. An extractor ischarged with this mixture and an alcoholicsolution is gained in the classic reverseflow procedure. This solution contains thewhole spectrum of hop bitter compoundsas well as a part of the tannins.

    Evaporation:Solid particles are completely separatedfrom the alcoholic solution via a centrifuge.Afterwards a concentration of the solutionis obtained in an evaporator at low eva-poration temperatures and under highvacuum.

    Ethanol Extract

  • Ethanol-Extract - Chart showing the production

    Homogenising:The hop extract is homogenised in acollecting tank.

  • Appraisal of hop aroma

    For the first time an aroma appraisal wasconducted for all the German hop varietiesavailable on the market even the new ones- in order to convey the specific features ofthe various hops even better.

    During several sessions at the hop-tradingfirms (Joh. Barth & Sohn, Hopsteiner andHVG) four samples of differing proveniencewere taken and evaluated from each of theleaf hops.

    The assessment was based on standard crite-ria which had been determined in complextest series during the spring: On the one handthe intensity of typical hop aromas such asflowery, citrous, fruity, current-like,sweet and spicy. On the other hand theoverall impression from harmonious topungent, from "long-lasting to quickly disappearing and from "mild to intensive.

    The aroma appraisal was conducted by selec-ted representatives from the hop-trading firmsJoh. Barth & Sohn, Hopsteiner and HVG, theHop-Growers Association and the ResearchCentre in Hll all of them hop noses withmany years of experience in assessing hops.

  • Brewing trialsCharacterising the aroma

    and taste profiles

  • In order to complete the characterisation ofthe hop varieties described in the CMAVariety Portfolio on hand with regard totheir agronomic, analytical and sensory properties, in 2005 brewing trials were con-ducted in an experimental brewery in 2hlscale. Furthermore a documented brewingprocess was used which will also allownewly authorized varieties in the future tobe brewed according to this procedure andthe results to be included in the VarietyPortfolio.

    Raw commoditiesWater with a low residual alkalinity wasused with a very pale, extract strong pilsnermalt. With a gentle mashing method thisresulted in a very light beer with only aslight malt flavour, which is the basic requirement for an optimum assessment ofthe hops used. Representative, pure varietypellets, type 90 of the 2004 crop were usedfor the hopping.Where this was not possible due to theamount being too small, ground leaf hopsamples were used. In each case the bottomyeast was obtained fresh from a brewery.

    Brewing processThe pilsner malt ground on a two-roll millwas mashed in an infusion mashing pro-cess (refer to diag. below) and drawn off ina lauter tun (first wort and 7 after worts).Following that, the wort obtained wasatmospherically boiled for 85 minutes inthe coppers by means of an internal boiler.The hop dosage was calculated accordingto alpha-acid and was made in considerationof the yields known in the experimentalbrewery. 60% were dosed at the beginningof the boil and to obtain a distinct hoparoma 40% were dosed in the whirlpool.

  • At the same time hop varieties were treatedequally, otherwise the contribution a bitterdosing can make to the beer aroma com-pared with an aroma dosing can hardly beevaluated.After a 20-minute rest in the whirlpool the wort was cooled to 7 C, aerated andpitched with 20-25 million cells/ml.After 7 days primary fermentation at 8 C itwas piped with residual extract and matu-ration was carried out at 14 C. When theattenuation limit and diacetyl degradationhad been reached, it was refrigerated to 1 Cand stored for 3 weeks.Filtration was by means of a kieselgur hori-zontal filter with following membrane filtercandles (1.2 and 0.45 m). Bottling was in 0.5 litre disposable bottles with double pre-evacuation and levelling correction withpure CO2.

    AnalyticsThe beers produced in this way were subjectto a beer analysis (original gravity, alcohol,degree of attenuation, pH, CO2 content, foametc.), in order to ensure the comparability ofthe trials. Furthermore the hop-specificanalysing criteria bitter compounds, xan-thohumol and iso-xanthohumol content,total polyphenols and linalool content wereanalysed and stated in the supplementBrewing trials for each respective varietyin the Variety Portfolio.

    Sensory evaluationThe beers were assessed sensorily byexperienced tasters in the hop industry.The tasters were thoroughly trained for this task using a specially developed tastersheet (illustrated overpage).At the same time particularly the intensityof the hop aroma in smell and taste wasassessed as well as the intensity and har-mony of the bitterness.For the evaluation of the aroma impressionsthey mainly fell back on the terminology

    used in the hop evaluation, by which thedescriptors fruity, flowery, citrussyand hoppy (spicy like fresh hops) wereadopted. In addition the descriptor herbal(in the positive sense of herbal) was adop-ted.A sweet taste in the beer usually comesfrom malt or otherwise inadequate fer-mentation and a currant aroma in beer isknown to be linked with aging. Thereforean assessment was omitted with regard tothese impressions.

    For the aroma impressions the evaluationof these tasting results was shown separa-tely for smell and taste in the spider dia-grams, the bitterness was shown in a barchart.

    Certification of hops

    The German hop-growers have always placedgreat importance on excellent quality andtransparency in the production of their hops.Not only since the corresponding EU regulationscame into force have they guaranteed traceabi-lity through certification for each hop lot withregard to production region, variety, crop year,hop farm and hop yard.

    As early as 1538 the Eichsttt Prince-Bishopawarded the first German hop seal to thetown of Spalt in order to document the authenticity of the aromatic Spalt hops. Forthe first time in 1929 one single law for

    Germany was passed the Hop ProvenanceLaw, which was replaced by the 1996 HopLaw. Today three EU regulations control thehop certification: the Hop Law at nationallevel as well as the regulations for implemen-ting the Hop Law at the state level.

    According the the state regulations sevenhop producing regions in Germany have beenlaid down by law (refer to box on next butone page). Only hops which are produced inone of these regions can be certified and con-sequently marketed. The hop producers andthe trading firms undertake the costs.

    The spirit of beer Hops from Germany

    First certification of the leaf hopsIn May the hop-grower gives a hop-producerdeclaration to the producer group in whichhe provides information about his hop acrea-ge and the varieties grown. He receives a pro-ducer identification card and the hop sealfrom the Hop-Growers' Association.Once the hops have been harvested the hop-grower seals and marks the packages anddeclares the origin of the hops; this is thenconfirmed by the Hop-Growers' Association.Each package is given a seal with the desi-gnation German Seal Hops and in additionthe following is indicated on it: the country of origin the production region the crop year the variety and whether the hops have been

    treated or not.

    The hops are weighed in the seal hall, in thecertification depot or directly on the farm andthe weight is entered on the weighing certifi-cate. The Hopfenring takes samples from theindividual hop lots, which are then sent on toan independent laboratory for quality control(refer to Chapter Independent QualityControl). If the minimum legal requirementsare not fulfilled then the Hopfenring is infor-med respectively. Then it is not possible tocertify the hops.

    Afterwards the hops are certified by thedistrict authority or by the Hopfenringappointed by the Landeskuratorium frpflanzliche Erzeugung (LKP). At the same timethe seal on the packages is supplemented bya sticker with the final designation.

    In addition the Hopfenring issues an accom-panying certificate which states the hop sealdata.

    During all these steps there is no lack of control:The information on the hop producer declara-tion is checked by the staff at the FederalInstitute for Food & Agriculture. The declara-tion made by the hop-grower on the origin ofthe hops is confirmed by the hop official fromthe Hop-Growers' Association. The results ofthe weigh-in as well as the certification arecontrolled by the government.

    All data converges at the offices of theHopfenring: There they undertake the centra-lized data collection and inspection, there therecords are kept on the certificates issuedand the documents filed in their archives.

    Second certificationAfter the first certification the natural hopsare delivered in rectangular bales to the pro-cessing works. When opening and furtherprocessing the packages the staff break theseals of the first certification.

    Pellets, extract or hop powder or treated hopcones are for example made from leaf hops.A complete process is prerequisite for the cer-tification of these refined hops.

    An official inspector is always present andrecords all in- and outputs in a log book.

    Staff fill the refined hops i.e. pellets, extract,hop powder or hop cones into individualpackages and pack them in boxes.

    The description of the contents, the varietyand certification reference number is statedon every package.

    The route to the Second Certification

    The hop bales are opened and put into the processing.In doing so the seal labels are broken.

    The leaf hops are processed to hop pellets or extract. The certification of the hopproducts can only be carried out if the processing took place in a complete operation.

    The products are filled into single packets and packed in cardboard boxes. The following informationat least is on each packet: description of goods / variety / certification reference number.

    Each lot is given a certificate. This contains at least the following information: description of goods / certification reference number / the final weight and/or gross weight / the placewhere the hops were grown / the crop year / the variety. In addition the date of processing must be stated.

    DevelopmentsIn recent years other quality assurance sys-tems have developed beyond the require-ments of the hop certification: Among theseare for example the controlled, contracted

    production (KVA) or the certification for indivi-dual farms according to DIN EN ISO 9001, inwhich the hop-grower records all measuresetc. which are undertaken in his hop yard.

    A courier service collects these samples inlead-sealed sacks and brings them to anindependent laboratory where they are ana-lysed within 24 hours. First of all the staffensures that all seals and lead-seals areintact before they open the specimen sam-ples. Every single sample is given a bar-codelabel with an unmistakeable laboratory andanalysis number.First of all the homogeneity of the sampleand the data on the weighing certificate arechecked.
