Hi all,
Going to do a beer next week (1048 OG, 5.5 gal batch). I harvested Calif. ale yeast WLP001 last night from a previous batch I bottled.
According to Mr. Malty, I need about 90ml of repitched slurry to do the job. That seems to be right about what I've got in one of my jars. Actually, if I adjust the date back a week (since I won't pitch this for another week), it says I need 103ml.
I have two questions:
1) should I do a yeast starter, or would that be too much yeast (I assume about 180ml)? Or, is it for some reason not good to do a yeast starter from harvested yeast in the first place?
2) I left the yeast concentration and non-yeast % on Mr. Malty at the default because I had no idea how to assess this. Any thoughts?
Thanks!
