"Juicy" Pale Ale (100% Galaxy)



Since my New England style IPA turned out so well I wanted to brew it again. Although the beer was very drinkable, it did clock in at around 7.3% ABV, which made drinking a lot of it while remaining functional difficult. I was curious if I could replicate that beer at a lower ABV. Along those lines, I’ve been curious to see if the New England style IPA is due to the yeast, the grain bill, or the hops, as has been much analyzed in beer forums. I’m personally on the side of the type of hops and when they are added that provides the “juicy” flavor and aroma. I also think that the yeast is providing much of the body that is talked about for this style and the hazy appearance.

To test my theory I changed a few things from my juicy IPA recipe. Obviously the lower ABV will affect aspects of this beer so it’s not a true comparison, but I can still get a pretty good idea of what is different and what’s the same. I also changed the hops and went with a 100% Galaxy hopping schedule. The grain bill is built more off of what I would think to be a West Coast style, yet the hops are fruitier than traditional West Coast style IPAs. I chose to use the same yeast and bittering addition, yet I removed the fermentation hop prior to pitching yeast and added a late dry hop after fermentation. I felt that my NE IPA could have used more aroma, which I think it lacked because it didn’t have a traditional dry hop. I’m also not sure what if anything the fermentation hop prior to pitching did for the beer.

What I’m looking for in the end is a similar hazy beer, which is dry but has a fluffy full mouthfeel, with low bitterness and more fruity hop flavor and aroma.  Will a different grain bill affect mouthfeel and hop flavor?

    1. Usually 36-48 hours, depends how high I want the carbonation. If need it quicker I'll crank it up higher so it takes less time.

    2. When it's ready to serve i generally decrease the pressure by venting. I'm not too concerned with losing aroma, there isn't much head space to begin. If venting will cause me to lose all the hop aroma I'm doing something wrong. My serving pressure is 10 psi so I'm not venting that much anyway.
