Subject: Old yeast report - IT'S ALIIIIIVE!!!!!
|
Following a discussion on here last Wed. about the viability of old yeast, I went home and pulled a tube of WY1388 that I'd had for a LONG time out of the fridge. Looked at the date...April 8, 2003! So I boiled up a qt. of 1.035 wort and added about a tsp. of yeast nutrient. Pitched the tube into it at 4 PM last Wed. Today (Fri.) as of 7 AM, the starter was rockin' away! I didn't know if the yeast was viable at all, and I certainly didn't expect that kind of activity that quickly. There are no off aromas, so I have to assume it's actually the yeast fermenting and not bacteria. I'll step it up early next week and use it to brew a Duvel type of thing next weekend! --------- >Denny -- Life begins at 60...1.060, that is.

I pitched the initial tube into about 400ml of 1.038 wort on a stir plate. It had weakly fermented most of the wort by the next day, but under a micrscope the cell count still looked fairly low -- and there were lot's of dead "flakes" in the starter. I poured off about 200ml into 400ml of canned wort, and just let it ferement out at room temp with no stirring so I could better gauge the aroma/taste of the ferment. Shortly after pronouncing it dead on this NG it started up and completed a nice vigorous fermentation. Smells ok -- I'll step it up to a full starter next week and do a helles or other small beer -- then my first Samichlaus clone. Yee-hah. -- (Replies: cleanse my address of the Mark of the Beast!)

It was amazingly dead, though -- lot's of useless little flakes of yeast colored blecch swirling around the initial starter. Smelled mighty belgian when I opened it up -- but this yeast is actually supposed to do a nice belgian ale when fermented warm. Second round of starter smells notmal to have been fermented out at room temp. I've been looking to use that canned wort for something. I think it was about two years old -- survived Katrina and everything. I guess the real test will be the first beer -- I've never used this yeast before. -- (Replies: cleanse my address of the Mark of the Beast!)

I was astounde when I realized I'd had that yeast in the friodge for 3 1/2 years, and even more astounded to see it take off after 36 hours! > Second round of starter smells notmal to have been fermented out at room > temp.

I think you're in for a treat. ----------- >Denny -- Life begins at 60...1.060, that is.

Last night I was celebrating Kazakhstan National Flag day. Had a Skullsplitter, EKU 28 and a Samichlaus. The difference between the EKU 28 and the Sami was striking. Obviously Sami is bigger and dryer -- but it also has these nice peppery notes that make it more interesting than the former, and atypical for a lager. Can't wait. Of course, with the amount of aging this beer will need, I guess I'll HAVE to wait. I'm going for the full 1.130 OG. Should be ready by around this time next year at the earliest. -- (Replies: cleanse my address of the Mark of the Beast!)
