Suggested Response - Q2
*What is a typical extract efficiency for each of the mash tun, lauter tun and mash filter. What is the main reason for their difference?
Response:
Compared to malt extract values determined by a standard laboratory mash, the following are typical:
Mash tun – 97%, lauter tun – 98%, mash filter – 101%.
The finer the grind, the better the extraction efficiency. The finer the grind, the smaller the husk fraction in a plansifter analysis. Combined sieve one and two husk fractions are typically:
Mash tun – 40%, lauter tun – 25%, mash filter – 5%.
