I've got an American (lightly hopped) ale in the fermenter at the mo.
I used US-05 for it, which was washed and reused from an Irish Ale I'd brewed a few months back.
I'm transferring this to secondary today, and wondered could I use the yeast cake straight away in another batch of beer (Kolsch type) or do I need to "let it settle" and then create a starter?
You can reuse the yeast cake but I would usually just use a small portion of it e.g a large ladle's worth. You run the risk of overpitching if you use the entire yeast cake (unless you're brewing a higher ABV beer).
ok cool, yeah I was thinking about a cupful or so. Do I need a starter? I'm guessing not.
No need for a starter as there'll be plenty of viable yeast cells in a cupful. :)
Excellent, thanks Irish Goat. I'm too impatient (and a cheapskate to boot) to buy a White Labs yeast and wait for the starter to kick off, hence using US-05 for a Kolsch style beer!
Following a kolsch type after Irish ale is gonna get you in trouble :(
How much is a packet of 05 ;)
Ah its not really the cost, just have the yeast and would be a shame to let it go to waste. Gonna try it anyhow tomorrow as I have no other yeast. Sure feck it
