These videos will show you the BIAB (Brew in a bag) method of all grain brewing. Imagine making a cup of tea. Same principal. Here in Norway this is often referred to as “The American way of brewing”
But I don`t know if Americans use this more than others.
The BIAB method can be compared to brewing a cup of tea. You have a casserole with water set to the temperature for striking the bag of malt into, and thats what you do. Dip it in and make sure it is properly soaked through and through. Then let it stay in there for the right amount of time depending on your recipe.
Just watch these videos here to get more on that subject.
