alpha acid aspirations chunk

Chunk, the second DIPA in the Alpha Acid Aspirations series of home brews I am cooking up. Blast, the first, received high accolades from my friends.

With Chunk I was trying to create a more robust DIPA that had an above average amount of malt backbone. I attempted this by using Maris Otter as part of the base malt (split it 50/50 between Maris Otter and 2-row). Mashed at 151, so I added a pound of table sugar to help dry it out.

This beer was loosely inspired by Furious by Surly Brewing Company. I took to 11 by making it into a DIPA as well as changing the hop profile. Enjoy!
