I've currently got a sour aging in my ferm chamber. It's been in there for 2 months and it's been a steady 62 degrees. I'm wanting to put together a couple lagers but am afraid of what the lagering temps could/would do to the sour. I guess I could move it to an upstairs closet for a couple months where it stays around 65.

Suggestions?

I have fermentors of sours and non-sours sitting right next to each other all the time. The bacteria arent going to climb out through the airlock, fly through the air, and then climb down the airlock into your lager no worries man.

I don't think he's concerned about the sours infecting his lager, he's concerned about the effects of the lower lager temps on the sour.

Depending on what bugs you're using in your sour, I think the cooler temps are likely to slow them down a bit. Best case scenario, it means you'll be waiting a little longer before the sour is ready. If it were me, I'd move it to your closet and let it age there at 65F.

Thanks, didn't know if disturbing the sour that much was worse than the colder lager temps.

I actually think it is better for sour beers to have mild swings in temperature. This is more important when aging in barrels because it helps with oak extraction.

I remember speaking with Eric Salazar of New Belgium and he was discussing the influence of the location of each foeder and how it makes a big impact on the beer. And I remember something to the extent that the foeders closer to the doors where his favorite and much more complex.

I would also age it in your closet. And the mild shaking should not influence the beer too much. Just try to be careful to introduce too much oxygen.

The only disturbance to moving a sour is causing the pellicle to fall...

Thanks, there is a little swing in temp in the closet, anywhere from 62-68 degrees normally. I think I'll move it there tonight.

There's really not much growth on top as of now. Is that my main concern?

Just because I'm curious now what happens if the pellicle falls?
