How Good is Your Grist?

The American Society of Brewing Chemists coordinated a collaborative test with 12 breweries on a method to check the coarseness of milling with sieves. This method can also be useful to homebrewers, because a correct mill setting greatly impacts the efficiency of extracting fermentable sugars. We will discuss the method, results from homebrew clubs, and how the impact of coarseness can be seen in wort. We will also demonstrate the manual sieve method.
