I followed this recipe for making an APA.
Since I have a smaller brewing kit (10~12 liters pan and fermentation bucket), I divided the ingredients for two batches:
First one following every step and exactly the same hop additions. Also for the dry-hopping part.
Second one I added some Columbus hops for the hop additions and dry-hopping as well. The other main difference was that I used also a Safale S-04 instead, since I was without US-05.
Both of them I did dry-hopping from the day zero of fermentation.
The first batch was okay, it lacked maybe a little bit more time for the dry-hop to be better, but the second batch, every bottle that I opened it produce a lot of foam and start to come out of the bottle loosing almost half of the beer and the remaining part is complete flat...
Can some clarify exactly what happend? I mean, I'm blaming the yeast since is not the one used for this kind of recipe, but maybe there's more to that.
