A 150 ml glass of red wine runs ~127.5 kcal — a full bottle is ~600. The per-100 g profile is 85 kcal. The combined meta-analysis of 599,912 drinkers (Wood et al., Lancet 2018) found ~100 g alcohol per week as the upper threshold before life expectancy drops measurably.
How should I track Red Wine?
Liquid calories from Red Wine are easy to overlook because drinks do not trigger the same fullness signals as solid food. A meta-analysis (Wehling & Lusher, Am J Clin Nutr 2021) confirmed that people underreport beverage intake more than solid food. Most people pour 30–50% more than the label serving size without realizing it. Use a kitchen scale to weigh your glass or bottle once — you will know your exact pour going forward. This one calibration step can save you from hundreds of untracked calories per week.
