Mosaic Pale Ale Split: Conan Vs. Drie

I had another quick brew session (~3 hrs for all - grain) as time is quite limited with house projects and the baby. I wanted to make sure I had some hoppy beer on tap for my birthday BBQ. I also have been meaning to brew another hoppy beer with Brett Drie, since I loved my first Extra Special Bretter (ESBrett). Speaking of yeast, I recently was sent some Conan (Alchemist's Heady Topper) yeast from Derek at Bear Flavored Ales and some Brett Custerianus from Ryan at Yeast of Burden. It only made sense to do a large batch and split it to test the yeast.

For the hops, I happened to purchase some Mosaic hops earlier in the year when we were planning our 2nd batch for the barrel (still not brewed). I've read a good amount about this hop and many brewers are using it as a single hop. I thought I'd give it a go since I don't know anything about hop blending anyways.

As for the recipe, I wanted something fairly simple since I want the yeast flavor differences to be obvious and to taste the hops. The recipe is about as basic as possible. I did make one tweak in which I added some rye malt to help build some body that the Brett Only batches would need.

Tasting Notes at Kegging:
Conan - Fantastic - huge fruity esters from both hops and yeast, nice firm bitterness and tastes pretty dry with the high F.G. (1.017)
Drie - Aroma is great and full of fruit, taste is a bit strange with some slight tartness that doesn't work with the bitterness, then a phenol astringency in the finish - Not good and I'm pretty sure my pitch of Brett Drie is now going to be retired.
Custersianus - Very fruit forward with that ripe funky nice to let you know its wild. Nicely dry and a bit thin, no astringency or tartness

Official Tasting Notes coming soon (hint: Conan version is almost gone- yum)
