Title: Bananananananananananana.......
Post by: Ouroboros on November 19, 2017, 04:09:10 AM
I just had an awesome experience: I poured my first glass from a keg of Coopers Sparkling Ale...and it was awful...it tastes like a freakin' banana.

I thought, "Okay, I vaguely remember that there was some amiss when I brewed this...what was it???"

And then I remembered. I used two packets of the yeast which comes with the Sparkling Ale...one packet off of the can, and another I'd saved in the fridge from the top of another can I'd brewed months before using a different yeast. I fully expected that the packet in the fridge was just fine, but I think the out of date can of Coopers...did I mention it was out of date? Well, it was, by about a year...I have reason to believe that it might have been very, very improperly stored and that the yeast on it might have been dead from having been stored at too high of a temperature. That's why I used the second packet of yeast, after all. I was expecting that, at the very least, I'd get one packet worth of good yeast, and maybe two!

Anyway, when I went to rehydrate the yeast, I accidentally spilled one of them all over my kitchen counter. Close to half of it was left in the packet. So now I had 1.5 packets of yeast to use instead of 2. But which one spilled? Was it the one I thought was probably improperly stored and dead? Or the one out of my fridge? No idea.

So I tasted this...what I'll call, "Banana Sparkling Ale"...and I remembered this episode. I'm thinking that the yeast that spilled was the good yeast and the other packet was completely dead. This means I pitched, maximum, 1/2 of the recommended amount of viable yeast. I thought, "I'll bet that banana flavor comes from under-pitching," and then I Googled. Yep, that's right. Ugh.

So that's what's awesome. I actually get to taste and experience for myself what an underpitched beer tastes like. Big time banana.

Can this be fixed? Some kind of hop tea to counter it? I'm guessing not, but anyone who has had a positive experience fixing such a thing, I'd love to read your thoughts.
