What is Malt?
• Grain that has been– Soaked– Sprouted– Dried– Kilned
The goal is to convert insoluble starch chains within the grain into water soluble starches available to the fermentation process
About Barley
2-row barley– Lower nitrogen/protein– Lower husk content for
filtering/lautering bed– Bigger kernels– Imparts less of a grainy
taste
6-row barley: more enzymes, good when lots of adjuncts, extra husk content
Why Barley?
Barley has a good balance of starches, sugars, and proteins for brewing.
Beer is made from other grains, but for western standards of body, clarity, flavor balance, barley works best
About 70% of the world production of malt is barley malt
Adjuncts
• Any unmalted source of fermentables in brewing:
• Whole maize or grits• Oatmeal• Corn starch• Rice or rice grits• Flaked barley• Flaked rye
Adjuncts are also…
• Honey• Sorghum• Caramel• Molasses• Maple syrup• They tend to offer starches but little protein• They tend to contribute less body
How is Malt Made?
Choose grains with intact kernels that are about the same size, moisture
content, and variety
Making Malt
Soak the grain until it begins to sprout (without drowning it)
Germinate the grain:
Acrospire: the new growth out one end of rootlets and a bit up the back
Modified, under modified, over modified?
Making Malt
• Kiln the grain
Dry it out! Roast it for color! Here’s where the art really comes in.
Then shake off the acrospire
Older malting kilns…
And the modern malting floor
A short diversionto Nottingham…
What else does malt do for beer?
• Malt adds color!
• Important characteristic of any style
• Color is mostly from malt, but also from intensity and length of boil
Or, if you prefer to think of it this way…
