Your body processes one unit of alcohol per hour, on average. That 9.75 unit bottle? It takes your liver nearly ten hours to clear it completely. So if you drink the whole bottle in an evening (I’m not here to judge, but I’m side-eyeing you), you’re still over the limit the next morning. It’s the reason “just one glass” at dinner can leave you foggy-headed during your 10 AM meeting.
The real kicker is that most people think a “glass of wine” is a unit. Nope. One glass is often two to three units. That’s why the “I only had two glasses” defense doesn’t hold up when you’re explaining your 4 AM snack choices. The math is a harsh but honest friend.

What this means for your weekly tally
If you’re someone who enjoys a bottle of red every Friday and Saturday night, you’re looking at roughly 19.5 units per week. The official recommendation is maximum 14 units spread over several days. So you’re already in the “high risk” zone without even touching a Monday glass. It’s not about fear-mongering; it’s about knowing what you’re actually drinking.
But hey, maybe you’re a glass-every-other-night person. A 175ml glass of 13% red, four times a week, comes to 9.2 units. That’s under the limit, but just barely. The margin between “moderate drinking” and “oops, I’ve overdone it” is thinner than a cheap supermarket Bordeaux.
If you want to enjoy red wine without the unit anxiety, try these tricks: switch to lower ABV wines (look for 12% or less), pour smaller glasses, or alternate with water (boring but effective). And never, ever let your friend the half-marathoner catch you with a full bottle. She’ll never let you forget.
So next time you’re uncorking a bottle of red, take a moment. Look at the ABV. Do the quick mental math. Then absolutely enjoy it. Knowledge isn’t the enemy of pleasure; it’s what keeps you from waking up with a wine hangover and a profound sense of regret. Cheers—and count those units, you magnificent rebel.
