There is an easy, short answer to this, and a long more informed answer to this. The easy, short answer to this is that there are never quite enough glasses of wine in a bottle – but that’s just me! Now, all jokes aside, the actual answer depends on a number of different factors, which I’ll delve into now.

The Type of Wine

This is the first port of a call when deciding how many glasses are in a bottle of wine. Sparkling wine, Champagne or Prosecco are typically drunk in a smaller serving – in bars and pubs this is normally a 125ml measure. The bottles are the same size as most standard bottles of wine (750ml) so as such, you can get a wonderful 6 standard glasses of sparkling wine out of a standard bottle.

With regular wine, such as red, white or rose, this depends on the drinker themselves. When out and about, a small is 125ml, a medium or standard is 175ml and a large is 250ml, so it really does depend on how big you like your glasses. If you like a big glass (and don’t we all) that means you can get 3 glasses to a standard bottle.

And now for the most efficient glass-to-bottle wine – fortified wine. Port, in particular, is served in a double measure as standard, this is normally a 50ml. When you consider that a standard bottle of port is still a 750ml bottle, you can get up to 15 glasses of port out of a bottle – score!

The Type of Bottle

Now, all of the above was working off the assumption of a standard size bottle of wine, but there are many different sizes to choose from. They go all the way from a Split (187ml) which are the tiny bottles you see on planes and trains, all the way up to a Nebuchadnezzar which holds a whopping 15 litres of wine.

Obviously, you can’t just pop down to your local shop and grab a Balthazar (12 litres/16 bottles) but if you buy your wine online or are in a wine bar, you may be able to buy a magnum which is twice the size of a standard bottle.

However, on the other end of the scale, if you’re in a restaurant, you can often buy a half bottle or a carafe, something which might be more wallet-friendly than buying individual glasses or buying a bottle when you don’t quite want that much – definitely something to consider. (See our half bottles here.)

Of course, these are the UK standards, and in different countries, they can use different measurements, but now you have the basic information to get you on your merry way.
