Cold Fermenting

[komomos]

My yeast S-23 needs 52 F. But I went deeper. I'm on 42 F. Slow but bubbles. I have lots of time.

Should I stay here and wait for one and a half months to ferment? Is it good idea?

According to the website:
9-22°C (48.2-71.6°F) ideally 12-15°C (53.6-59°F)

I typically use this yeast at 52° and it works great. I would be concerned about the yeast not getting the job done and maybe going dormant at that low temperature. I would probably warm it up but people do stuff all the time that I don't and still make better beer than me.

I have had good ferments with S23 down into the 30s, it may be slower, but you will have a nice beer
