slow starter
« on: March 18, 2012, 08:11:15 AM »
I'm working on a starter for wyeast 1338, and I knew it was a slow yeast going in.  I popped it about 2pm friday, and it had swelled to maximum by the time I got my starter going at 7pm.  I'm doing a 1L starter, and it's currently at 1.022 (5.5 brix) after 36 hours.  I don't have time to wait any longer.  is there any harm with cold crashing this as is, decanting and tossing in what I have?  or should I use a dry yeast backup and let this go and use for next time?

I think the only harm is the potential for under pitching.  Whether or not it is significant enough to worry about depends on your OG.

I'm not sure 1 pack in a 1L starter is going to give you the cell count you'll need (236 billion) for a 1.065 wort. On a stir plate you'd need 1.5L, without you'd need 4L.

There's a free pitching rate calculator here:

Also, with a 1L starter you don't need to (IMO) worry about cold crashing a decanting, you should be ok pitching the whole thing in there without an effect on flavor

so you say you do not have time to wait any longer but you do not yet know your actual og. I say, if you haven't brewed the beer yet you still have time to let it work. you can pitch the day after you brew.

Are you using a refractometer? Have you corrected the reading? http://seanterrill.com/2012/01/06/refractometer-calculator/
