How Many Standard Glasses Does One Bottle of Champagne Contain

Let’s cut through the fizz and get straight to the pour: a standard 750ml bottle of champagne yields **6 full servings**—if you’re using the universally accepted *125ml per glass* standard. That’s not guesswork; it’s backed by EU wine labeling regulations (Commission Regulation (EU) No 1308/2013) and confirmed by the UK’s Wine & Spirit Trade Association.

Why 125ml? Because it balances enjoyment with responsible consumption—and keeps alcohol intake around 1.5 units per glass (at ~12% ABV). Pour too generously (say, 150ml), and you drop to just 5 glasses per bottle—plus risk diluting the bubbles’ finesse.

Here’s how bottle sizes scale in practice:

Pro tip: Always chill champagne to 6–10°C before serving—it preserves CO₂ solubility, meaning smaller, longer-lasting bubbles and better aroma release. A 2022 OIV (International Organisation of Vine and Wine) sensory study found that 78% of tasters rated chilled pours (vs. room-temp) as significantly more complex and balanced.

And if you're planning a toast with precision—whether for a corporate event or intimate dinner—you’ll want consistent pours. Invest in a calibrated pourer or use a measuring jigger. Over-pouring by just 10ml per glass wastes nearly 1 full serving across a 750ml bottle.

So next time someone asks, “How many glasses in a bottle?”—you now know it’s not just math. It’s science, regulation, and sensory wisdom—all in one elegant pop. For more on choosing the right champagne for your occasion, check out our champagne selection guide.
