The average person drinks 1.5 glasses of wine a day? I don’t know where that stat came from, but I always knew I was way above average! I get much better mileage than that. If you work out the math, it appears those are Canadian (or UK) gallons, at 8 oz per glass. Or maybe it really does mean 6.4 oz per glass. Oh, I don’t know, all I do know is right now I need another glass of wine.
