Well...a bit disappointed with the plastic fermenters.
Brewed 20 gallons of Munich Helles a month ago, two 10 gallon batches. Same recipe, same yeast (W-34/70).
10 gallons went into stainless conical ferment vessels, 10 gallons went into these new Genesis plastic containers.
Neither beer has been racked into the keg as of now, but the beer in plastic has a very noticeable off flavor. Can't quite put my finger on it, but it is there and it is not good. In fact, bad enough that this batch might be a candidate for a one-way trip to the toilet.
