Imperial Yeast has been up to some interesting things lately, and they recently announced

0:03.8

a product we are super excited about. If you're familiar with Imperial Yeast, you're likely

0:07.7

aware of their classification system. A is for AL as an AO7 flagship, L is for Logger as

0:12.9

an L17 harvest, and so on. While they recently released the first strain in their I series,

which stands for Imperialis and refers to non-GMO hybrids or derivative yeast strains developed

0:22.8

by Imperial Yeast that have been honed to exhibit the traits today's brewers most desire.

The initial offering, I-22 Capri, is a hybrid of A-38 juice and A-43 Loki, two of Imperial's

most popular strains for hop forward IPA. Whether you're into this style or just enjoy

enemy. We've known this for a long time, especially Bruloscopy. What is really interesting about it

1:33.6
