#103 - White IPA

Wow, it's been a while. Six months since the last brew day. Ugh. Maybe I'll go back and fill the 2015-6 gap on this page at some point...

Time to burn some leftover ingredients (DME, older hops) by doing a partial mash with new grains and some new hops. Working with a cut of Conan yeast that I've been reharvesting/reusing since 2013, so I was fearing I might have to buy some new yeast, but after a good starter it is kicking butt on the ferment. Lowered the AA for the older hops (just an estimate based on online research), so who knows what I'll get from them. I used them primarily for bitter, and pushed the fresh citra up front. They smelled fine... what can possibly go wrong? Fun to be brewing again...
