I'm a new brewer, just have 3 extract kits under my belt, hoping to do my fourth batch tomorrow. My first three were kits, two from Midwest and the other from a local shop. For the next one , I individually bought the ingredients for the Three Weisse Guys wheat beer that's in John Palmers How To Brew book. But I noticed a difference - all the kits I have brewed started out with an initial step of steeping a provided grain mixture in a muslin bag before adding the extracts and doing the boil. The recipes in the Palmer book don't include the steeping process. Why the difference or am I missing something? I'd hate to make the wheat beer without the step if its really needed. Thanks in advance for any advice.
