Great IPA/APA

[sutepan]

This turned out exactly as I had hoped, so I thought it might be worth sharing. IBUs are not as high as a lot of IPAs, it seems about half way between an IPA and an APA. Gravity at pitching was 1.061 and kegging 0.008(!). Nice hop-forward brew with great balance. Beautiful aroma from the Falconer's Flight and Amarillo. Settled out clear as clear can be. Spent four weeks in the secondary at 12°C, dry hopped for the last two. It was my second time using FF, the Amarillo definitely makes a nice compliment. I use Dartmouth water modified as shown in the recipe.

Right on. Gotta love the FF, and Amarillo goes great with it since it's just as awesome. My last IPA had a bunch of FF and used the rest of my Amarillo, plus some Citra. My next one will probably be FF & Citra unless I cave in and brew it before the group buy comes in.

I'm not sure what your water additions equate to in grams but I'd drop the chalk for an IPA with our water, probably the baking soda too. Personally I prefer a mix of some epsom, gypsom, and a wee bit of CaCl. You gotta love Dartmouth water for brewing though. Have you ever made a Pilsner?

[sutepan]

Not a fan of Pilsners to be perfectly honest...of course I've never tried brewing one myself so I'm sure that might have something to do with it.

I've always been too lazy to get deep into water analysis, so I definitely appreciate the info. I used to put gypsum in my water, but after reading (scanning really) online about water additions and playing with the water calculator in Beersmith, I arrived at the above additions, which have served me well. I'll take your advice tho, make some more adjustments for my next batch, and see if I can detect a difference. My problem is I'm trying new things every batch so have never really established a baseline for comparison.

Yeah stuff like that is a moving target, dialing it in bit by bit. I'm pretty happy with my IPA water profile so it doesn't change much now. John Palmer's book has some good info. I have the "water" book as well but haven't gotten around to reading it cover to cover yet.

It would be cool to brew a bunch of IPAs back to back and taste them side by side but then we'd be shitfaced all the time.
