Hello everyone, newer brewer here. After reading how to brew and also brewing with some friends I'm a little confused. I've done two batches, one a belgian wit and the other a two hearted clone. I'm doing full 5 gallon boils in a keggle using extract first dry and then liquid. In both cases I had a good rolling boil going for a full hour but in both instances I never saw the hot break. I don't even get a little foam. Is there something I'm doing wrong or is this common with extract? Should I try boiling even more violently next time? Thanks!
