Hi there.
I have one question, my son "accidentally" moved the thermostat of my keezer,in which I have 2 kegs with ales, and I noticed it a few hours later as the setting was not at 5 degrees Celsius, but it now was at -10 Celsius.
What happens to the beer once it gets back to "normal" temperature? I think it tastes different now, does the yeast reactivate with the change in temperature?

Any thoughts, ideas?

No harm done other than depending on style the beer may taste a bit different. That's assuming that nothing froze too much and expanded and caused damage.

At the temps you mention the yeast will not reactivate, though even if you warmed it up enough to whatever fermentation temp you used there should be no sugars left for the yeast to consume anyway.
