I thought I had some S-04 in the fridge, but it turned out to still be in a fermenter that wasn't really quite ready yet. However, I found a (very) old pack of Wyeast 1028 in the back of the fridge.... I wasn't really very confident in this, I gave it 16 hours or so in a nice warm place, and it hadn't really swollen, but what the hell, I tossed it in, and reclosed the fermenter. I planned on giving it a few days, and then, when the S-04 was ready, if it hadn't taken off, I'd pitch some S-04 on top.
That was today, and though it hasn't really taken off, it has gotten started. It's not alone though
