So, I bought
bactrack S80 on black Friday prices, and just had the first chance to use it last night.
We were having dept. xmas lunch.
I had 3 tankards of Goose Island IPA, (also had lunch) in 3 hours, walked home which took about 25 minutes, (you need to wait for 20 minutes since last drink), and bac was .056, tried again about 20 minutes after that and it was .053.
I was kind of surprised it was that high.
Actually just checked Goose Island and it says it is 5.90 abv, so I guess it does make as bit more sense now.
I think drinking something like a bottle of Corona, which is about 4.5 I think, an hour would be no problem, but I will find out.
