I probably give away 75% of what I brew. I haven't had a hang over in 20 years. I learned young. I've never had a DUI and won't be getting any. I did get pulled over leaving a bar two years ago. Golfed all day at a tournament where there was beer and mixed drinks at every tee. After golfing we went to the award banquet. I had a crown and coke there. Then to the infamous bar, where I had another crown and coke. So, when I was pulled over and had to do all the DUI touching your nose stuff, etc. and eventually did the breathalizer, I blew .02. The cop was amazed. He thought for sure I was wasted. He never did ask how much I had to drink lately, but only asked if I had been drinking. I told him of my day and said I'd probably had 6 beers and two mixed drinks. I knew I'd blow low on the breathalizer, so I didn't tell him I'd only had the two crown and cokes in the last six hours. All of the beer was in the mornign and early afternoon.
I drink responsibly, even at home. Maybe two in a day, at most usually. I make beer to try to create something that makes people go "Wow, you made this?". That is why I brew. For taste, not for alcohol.
