Dry Hopping Experiment

Whoah, my dry hop experiment (with this particular beer) gave me totally unexpected results. Cascade came out on top of the Amarillo. I think it had to do with a balance thing since I used a lot of amarillo at the end of the boil. The Cascade dry hopped beer was more complex and enticing where as the Amarillo Dry Hopped beer just seemed to be more 1 dimensional. Kegged the Cascade version and threw in an ounce of Cascade and an ounce more of amarillo in the Amarilly dry hopped version for good measure. I'll keg that one once they settle out.

I split this into two batches and dry-hopped one with 2oz of Cascade and one with 2oz of Amarillo hops. I was 100% sure I'd like the Amarillo better. Turns out, Cascade worked better. (for this recipe anyway). I used a lot of late addition Amarillo so I think the cascade beer was more compled because of the dry hopping.
