In 2026, health organizations like the CDC and the Australian Department of Health define "one drink per day" using the concept of a "standard drink," which contains approximately 14 grams (or 0.6 ounces) of pure alcohol (in the US) or 10 grams (in many other countries). To visualize this, one standard drink is roughly equivalent to a 12-ounce (355ml) regular beer (at 5% alcohol), a 5-ounce (148ml) glass of wine (at 12% alcohol), or a 1.5-ounce (44ml) shot of 80-proof distilled spirits like vodka or whiskey. It is important to note that many modern craft beers and wines have higher alcohol content (e.g., a 7% IPA or a 14% Shiraz), meaning a single glass may actually count as 1.5 or 2 standard drinks. Moderate drinking is generally defined as one drink or less per day for women and two drinks or less per day for men. In 2026, with the rise of "sober-curious" trends, many people are using mobile apps to track these "standard units" to better understand the long-term health impacts of their alcohol consumption.
