Northern Brewer Grapefruit Pulpin Brew Session

Manipulated mash and sparge water via Bru'n water calculations to achieve target IPA water profile. Even though I had pH strips, it was difficult to get a reading where I had a lot of confidence, but I feel like I achieved a pH in the low 5's - between 5.0 and 5.5. Reducing the running rate to roughly 1gal/10min greatly increased my efficiency, which had been closer to 60% in previous beers. Northern Brewer recipe card identifies an OG of 1.065 while I achieved 1.070, so I am pleased with that. Racked to secondary on 5/26. 2oz grapefruit peel with kit and entire grapefruit (no peel) soaked in vodka for 2 days and added to secondary on 6/1. Bottled today on 6/15. Final gravity of 1.011, just as predicted. Tasting the beer, lots of grapefruit flavor and some bitterness, not much hop forward flavor as I was expecting given the water adjustments. Color is darker than predicted SRM, more of an orange but not amber, and cloudy. I haven't been happy with Northern Brewer recommended priming levels - I feel it's too low on carbonation - so I increased the dextrose used by about 10%. Maybe this was too aggressive but we shall see.
