Since all of the fermentors are at Mark’s house, he’s keeping an eye on things. Fermentation has slowed down or stopped for most. He gave the kegs a quick roll to rouse the yeast, since some are very flocculent. He also raised the temp to 72F for a couple days to perform a diacetyl rest, […]
Yesterday’s brew day went well. First, I got the new pack of 1099 counted. It was still lower than it ought to be (67.6 billion viable cells, 98.5% viability), but enough for today’s brew. Second, the brewing went surprisingly well. We were pushing the limits of Marks’ equipment – mash tun totally filled, both keggles […]
I counted the number of cells in the four smack packs. Here are the results: Sample % Viability Viable Cells/ml Total Viable CellsWyeast 1028 90.6 8.64e8 1.04e11Wyeast 1098 97.7 7.83e8 9.39e10 Wyeast 1099 96.0 4.76e8 5.72e10Wyeast 1882 98.3 1.22e9 1.46e11 The 1099 has only half the amount of cells it ought to – only 57 billion. So I bought another pack […]
I’m getting ready to embark on a mega-brewday with a couple guys from the homebrew club. We are going to make 8 3-gallon batches of a special bitter and ferment each with a different English ale yeast. Here’s a list of yeast: Wyeast 1026 PC British Cask Ale Wyeast 1275 Thames Valley Ale Wyeast 1768 […]
Just found a case of Strawberry Mead the other day that I didn’t know I had. Rockin.
Been busy getting the house ready to sell, so haven’t had time to write about my Iron Brewer entry. Every year Iron Hill in West Chester is kind enough to supply our homebrew club with wort containing mostly Pilsner malt. Then everyone who participates brews any style of beer they like. The only rule is […]
I inoculated 2 1.6-L starters with Wyeast 1214 or Empire Brewing Company yeast for an upcoming beer. After the starter completed growth, the cells were counted using a Beckman Vi-Cell XR 2.03 automated cell counter.The Wyeast 1214 was 282.11e6 cells/ml and the Empire was 132.86e6 cells/ml. Compare that to the Wyeast 1056 I did last […]
I’ve begun a new experiment examining how to best scale up a yeast starter from a glycerol stock, plate, or slant. Typically when starting from one of these storage methods, a 5-10 ml culture is inoculated. From there one can either pitch that culture into the final starter volume (typically 1-2 L). Alternatively, one can […]
