Hi,
I tried to produce an alcohol free beer for my step-sister who is pregnant. It didn't work and I don't really understand why. I need your suggestions. There are the processes I used :
1) Canadian 2 row malt + carafoam = OG: 1.042
2) Mash at 83°C (181°F) for more body and less fermentable sugars
3) Only primary (wyeast Abbey ale) for 7 days = FG: 1.011
4) Final alcohol supposed to be 4.1%ABV
5) Heat primary to 80°C (176°F) for 1h30 to evaporate ethanol and mixing 4-5 times
6) Bottling with dextrose and adding fresh yeast
7) After 3 weeks, samples were tested on a GCMS (gas chromatography - mass spec) by a specialized company
8) Result : 5.1%!!
So, I don't really know what happened. There is more alcohol than it suppose to be. The only mistake I have done, I think, it's that I didn't stir continuously when I heated it to evaporate alcohol...
