fermentating ale almost accidentally frozen

[BigCask]

Doh! I almost froze my fermenting bitter after only 4 days of fermentation. Will it finish?

I have a freezer + johnson control thermostat/controller for maintaining fermentation temp, and accidentally left the thermostat out overnight. The beer probably got down to ~40 F.

I haven't checked the FG yet. But assuming it's not down to desired FG yet, any chance it continues to ferment properly after bringing it back to 65 F or so.... ?

The starting gravity was only about 1.45. I'm using wyeast london esb #1968 w/ a starter on stirplate. I got decent activity after only 4 hours or so ...

Thanks

you might want to rouse the fermenter again after it gets back to temp so it will resuspend the yeast and get it going again.
