One can get lost in conversions and the âhow big is your pourâ etc. Fundamentally, the math of how much alcohol is in the glass is very easy. Volume poured multiplied by percent alcohol by volume.
A 12.5% Muscadet, poured five glasses to the 750mL bottle gives you 5 ounces * 12.5% = 0.625 ounces of alcohol
A 15% Syrah, poured the same way gives you 0.75 ounces
A 7.5% German Auslese, poured identically gives you 0.375 ounces of alcohol, not surprisingly thatâs half the 15% Syrah
Rickâs single martini (Iâll just guess that itâs 2 ounces of 80-proof vodka or gin and no vermouth for easy math) is 0.8 ounces, which is a bit more than the glass of higher-octane wine. I theorize that more rapid consumption and the fact that the higher alcohol concentration leads to faster absorption rates makes a martini seem like it punches above its weight
A 12-ounce bottle of 5% beer gives you 0.6 ounces of alcohol.
As somebody pointed out, beers vary widely today. Many âImperialâ beers are up in the 8-12% alcohol range. Often, they come in a 750 mL bottle. Unless you share or stopper it, youâre plowing through the equivalent of a bottle of middle-weight (alcohol-wise) wine.
I think the original 1 drink = 1 beer = 1 wine was based upon 0.6 ounces of alcohol, or 5 ounces of 12% wine, 12 ounces of 5% beer, or 1.5 ounces of 40% alcohol. If you donât measure or fiddle with the strength of your drink, you canât make an apples-to-apples comparison.
The math is really hard when you try to determine your blood alcohol from how much you drank. So far as I know thatâs not possible to calculate because it varies depending upon diet, gender, whatâs in your stomach when you drink, how fast you drink, and metabolic rates.
I abstain from judgement on your question. I canât answer whether a bottle+ every other day is bad for you. I drink almost daily. A bottle+ of wine daily would be bad for me because it would adversely impact other parts of my life and I expect it would be a problem for my long-term health, although Iâm not qualified to make that assessment professionally. I donât see the every-other-day piece as the factor here. Itâs how much you are consuming in a âsessionâ that will raise flags with clinicians.
If youâre expecting actionable advice from the community here, you should realign your expectations. If youâre looking for moral support of your consumption, you should reflect upon why you need support from us. If youâre simply curious as to how many others out there fit your profile, I expect there will be some reluctance to disclose publicly, as this level of consumption does fit definitions of excessive drinking. I expect Italian and French norms might see this much wine daily as socially acceptable, especially if you split it between lunch and dinner. Itâs really easy to have 2-3 glasses at a meal that is leisurely in pace.
