Ah, the million-dollar question for anyone trying to figure out if that second glass is a brilliant idea or a future regret. Pinning down the exact amount of alcohol in a wine bottle is like trying to catch smoke; it all depends on the bottle you're holding.
While one helpful soul on the internet suggests a bottle of wine contains "around 13% alcohol," that's just the popular kid in the high school yearbook. The reality is much more diverse. A bottle of wine could be anything from a lightweight social sipper to a heavyweight champion, with its alcohol by volume (ABV) swinging from a gentle 5.5% all the way up to a formidable 14.5% or even higher.
Think of it in tiers of intensity. You have your low-alcohol wines, hovering between 5.5% and 12.5%, which are perfect for a light afternoon. Then you hit the Goldilocks zone, the medium-alcohol crew from 12.5% to 13.5%, where most of your everyday reds and whites live. After that, you're getting into high-alcohol territory, from 13.5% to 14.5%, where the wines are packing a bit more of a punch. And let's not forget the fortified wines, which can easily climb above that 14.5% mark and will definitely make their presence known.
So, while a standard 750ml bottle generally holds about five "standard" drinks, the potency of those drinks is a sliding scale. The best way to know what you're getting into? Check the label. It’s the only way to know for sure if you're sipping on a gentle breeze or a boozy hurricane.
