Looks like I’m in this whole experimental thing for the long haul. This time the Experimental Brewing Podcast is testing Biotransformation.

Question: Does Dry Hopping a Beer During High Krausen Produce a Organoleptic Difference. Note: If you’re like me, you had the confused puppy look with Organoleptic. Let me help ya, being, affecting, or relating to qualities (as taste, color, odor, and feel) of a substance (as a food or drug) that stimulate the sense organs. That helped me, hopefully that’ll help you also.

This one was an interesting experiment. The difference in the two carboys was the dry hopping schedule. As you can see in my notes. A trip interfered with dry hopping my second carboy, which I think threw it off a touch. But all in all the beers turned out reasonably well and it was not easy to distinguish between the two beers. I am afraid I wasn’t able to have the taste panel I really wanted to have, but you know that happens. I still have plenty of beer left, maybe I can update this post if I can get some other tasters on board.

Here is the tasting panel I held. Nine total testers, three of them picked the odd sample. One of the testers was determined to get it correct so she asked for another triangle test. Well unfortunately, she could not pick the odd sample on her second go around. After the opaque cups were tested, I gave each one a sample in a clear plastic cups. It was interesting to see how the difference in preference was when the samples were given in clear glasses.

Notes on yellow cup (odd sample):

• Slightly more hop forward
• Very Bitter, hop flavor astringent
• firm flavor

Notes on green cup:

• hint of hops, very similar to purple
• Strongest flavor of the three
• lighter, smells off

Notes on purple cup:

• hint of hops
• smooth, mild flavor
