So, I just bottled a Scottish Ale that I treated like an Eisbock and froze then concentrated in a random experiment I'm trying.

The full beer was about 3 gallons with an O.G. of 1.060 and F.G. of 1.015 for an ABV of 6.0%.

When I froze the beer and concentrated it, I was left with about 2 gallons. The discarded 1 gallon, at room temperature, had a gravity of 1.008. I forgot to read the gravity of the 2 gallons before I bottled it.

So, based on the information, do you know what the F.G. and ABV is of the 2 gallons I bottled? Is there a mathematical way to calculate it?

Thanks in advanced for the help.
