True Cost of Wine
Pick the wine style, serving format, quantity, and profile to see the alcohol load, calories, water loss, and sleep trade-offs right away.
Input parameters
Choose your wine
Change the pour, wine profile, quantity, sex profile, and optional weight. The details update instantly without forcing you to chase the result down the page.
Pick the serving size first so the wine math stays tied to an exact volume.
Switch between dry white or rose and dry red while keeping the wine-specific formulas intact.
Use the slider to match the total amount of wine in this session.
Optional personalization. Weight changes the relative dose shown in grams per kg.
Your wine at a glance
1 glass of Dry Red (14.0% ABV)
Estimated clearance window
1 hr 39 min
For the selected Men profile, this session contains about 16.6 g of pure alcohol and may take around 1 hr 39 min to clear. REM may start about 20 to 30 min later, and water loss is around 166 ml.

Body timeline
Tap through the night to see what changes
Choose a time point to see what the body is likely doing, how much alcohol is still being cleared, and what that part of the night may feel like.
What you may notice
You may feel warmer, more relaxed, or slightly flushed fairly quickly.
What your body is doing
Alcohol is still climbing in the bloodstream, and early sedation can arrive before much clearance has happened.
Sleep terms in plain English
What REM delay actually means
REM stands for rapid eye movement sleep, which is the dream-heavy part of the night. Alcohol often makes you sleepy early, then pushes REM later and can leave the second half of the night more broken up. If you want the deeper background, use the REM overview, the Harvard sleep explainer, and the REM timing review.
1. You may fall asleep faster[7]
Alcohol can act like a short-term sedative, so bedtime can feel easier than usual.
That is what the REM delay number means. The dream-heavy part of sleep gets pushed back.
Wine headache tax
Why wine can feel rougher than the calories suggest
Dry white and rose wines carry a lower congener burden. Dry red wines carry more histamine, tyramine, and tannins, which can push headache pathways, sympathetic activation, and next-day fatigue harder.
1. Histamine plus DAO blockade[9][10]
Wine can expose you to histamine while ethanol and acetaldehyde blunt the DAO enzyme that normally helps break it down, which can make vascular headaches more likely.
Tyramine can drive a short sympathetic spike first, then a rebound cranial vasodilation response that feels distinctly headachy later.
3. Tannins keep the night louder[11]
Red wines carry a denser grape-skin tannin load than dry white or rose, which is one reason the same alcohol dose can feel heavier in a dry red.
