How Many Glasses Are in a 750ml Bottle of Fortified Wine Like Port

Let’s cut through the guesswork: a standard 750ml bottle of fortified wine—think Port, Madeira, or Sherry—holds **exactly 25.36 fluid ounces**, but how many *glasses* does that translate to? It depends on your pour—and your purpose.

In professional tasting and service settings, a standard serving of fortified wine is **2 oz (60 ml)**—not the 5 oz used for table wines. Why? Because fortified wines typically range from **17–22% ABV**, nearly double most reds and whites. A responsible, flavorful pour respects both palate and physiology.

So: 750 ml ÷ 60 ml = **12.5 servings** per bottle. Most venues round down to **12 full glasses**, keeping the last 30 ml for top-ups or staff tasting.

Here’s how that breaks down across common contexts:

Data from the [International Organisation of Vine and Wine (OIV)](https://www.oiv.int) confirms fortified wines average 19.5% ABV globally—with Vintage Port often hitting 20.5%, while Ruby Port sits closer to 18.5%. That variance matters: over-pouring increases ethanol load faster than you’d expect.

A 2023 UK hospitality audit found venues using 2.5 oz pours saw **23% higher perceived bitterness and 31% more frequent palate fatigue** among guests—proof that precision elevates experience.

So next time you uncork a bottle of Port, remember: it’s not about volume—it’s about intention. And if you’re building a thoughtful wine list or hosting a curated tasting, start with the right pour.
