How soon is too soon to raise temperature on Fermentation.

[Grossy]

I have 15 gallons of beer that is ready to keg, and I want to cold crash it.

I have 10 gallons of an American Wheat that is fermenting in my fermentation freezer.

The American Wheat was brewed 4 days ago, using White Labs WLP400.

Really active fermentation has passed, would it be to soon to move the American Wheat from the 65 degree fermentation freezer, to inside the house which is 75 degrees?

This would free up the fermentation freezer, which I will then lower to 35 degrees, and cold crash the 15 gallons of beer that is ready to keg.

I am very concerned with off flavors that can be produced at higher temperatures.

what yeast are you using in the wheat? a lot of wheat yeasts will be fine at 75*F. if most of the fermentation has died down, then yes it's a good time to raise the temp.

If your in a rush go for it but I would wait a few more days at a minimum before you move it in the warmer temp. I usually warm mine up after it has sat in primary for 2 weeks.

After about 2 days, once the growth phase is over, its safe to raise the temp without the worry of getting off flavors.
so your good, dont worry about it.

Agreed, don't worry about it you can raise the temp. As far as wheat yeasts being ok at 75, not in my experience, unless you like bananas of course.

2 weeks is a little late. the idea of raising the temp is to encourage the yeast just as they are tiring from the peak of fermentation. if you wait 2 weeks, most yeast will have flocc'ed out by then. to me, sounds like the OP is at the perfect time to ramp up the temp.

I'd say you're fine to pull it now. Typically any beer I ferment in the lower 60's, I start ramping the temp up to 72 over several days as soon as I see fermentation slowing significantly. For a simple wheat ale, that'd definitely be within 96 hours of yeast pitching (assuming you had a reasonable, i.e. ~24 hr, lag time).

Going to higher temps won't impact the beer negatively at this point.

I usually wait until fermenation has slowed before I increase the temp 4-5 degrees. I bet you'll be fine at this point if you have to be. Otherwise, increase the temp a little for a day or two, then pull it out to the 75

Thanks everyone.

I made a stater and had huge activity in the airlock in 12 hours.

I'm going to lower the temp in the house to 72 degrees, and move the Wheat Ale inside.
