This morning I added the final volume to the starter. After completing the first two steps, the starter was crashed cooled and decanted. A final 2L of wort was added to the flask this morning. The starter sits spinning on a stir plate. The target cell counts is in the 400B ball-park.
I checked the gravity of the decanted spent beer, it had in fact fermented out to 1.008 (75% attenuated) which is bang on for WLP833. It had that distinct sulfur/egg smell common to lagers. I was a little concerned as I purchased this yeast on a clear out. The best before date was Nov 11. I have no idea what the real viability was so I assumed 10%. Worst case, I'll end up with slightly more yeast then I bargained for which I understand isn't such a big deal for Lagers.
Tonight I crush my grain and prepare for tomorrow evenings brew-night!
