I haven't dry hopped in a long long time, so essentially I'm considering myself new to it. Yesterday, I dry hopped my barleywine. It had been sitting in the secondary for about a month or so. It's now showing some action (bubbling near the surface, see picture attached) although I don't see much movement in their airlock. Is this normal for those of you who are more familiar with dry hopping? Should I proceed to allow the hops to be in contact with the beer for another 5 days as called for in the recipe? Any other advice? Thanks!
