My latest blunder occured when I was inspired by Drew's Zymurgy article on turning 1 beer into two. To make the long story short, I pitched a Belgian ale yeast starter into the batch that was destined to be a dubbel, and then I pitched my American ale yeast into the batch that was destined to be a dubbel. I pitched it into the wrong fermenter! That left me with no yeast for my IPA. Although it was 11pm, I live near a convenient mart that sells a small assortment of homebrew products. When I arrived, they were out of S-05 and S-04, my "go to" dry yeasts. So I got a Nottingham pack. Then I realized it was the recalled Nottingham that some homebrewers have complained about as non-starter. So I got a Windsor pack too. I pitched them both. To recap, it was 1 mash, 2 different beers, and 4 different yeasts. I'll sample the first bottle of the Notty-Windsor IPA today.
