When I brewed my first batch a few months ago, a red ale from a kit, I forgot to add the flavoring hops in the last 5 min. So what I did was dry hop them. After about 4 days when the vigorous feremntation was over I put the pellets in the primary and bottled in 10 days. I thought the beer came out pretty good, with a nice little hop nose. I just bottled an IPA, and I did the same thing, threw in the Cascade after the virgorous fementation phase ended. Everything I have read says if you dry hop, use a secondary. Is there any reason NOT to dry hop in the primary as I have done? I would rather not use a secondary partly because I am lazy and it is also one more stage that exposes the ale to possible contamination and or oxygen.
