Plan on about half a bottle of wine per adult guest for a standard party, which is roughly two to three glasses each. So for a two to three hour gathering, buy one bottle for every two people, then add a little extra as a buffer. That simple ratio covers most events without leaving you short or drowning in leftovers.
How many glasses are in a bottle?
A standard 750ml bottle pours five glasses at five ounces each. That is the number to memorize, because everything else builds from it. Restaurants and caterers pour a touch larger, closer to four glasses per bottle, but five is the honest planning figure for a party where people are sipping and talking, not measuring.
Once you know a bottle is five glasses, the math gets easy. Ten guests over an evening will drink somewhere between twenty and thirty glasses, which is four to six bottles. We always round up. A little wine held back is a gift to your future self.
How much wine per person for a party?
Here is the quick reference we give people who ask us at the shop:
- Short event, two hours: one to two glasses per person
- Standard party, three to four hours: two to three glasses per person
- Long celebration, five hours or a dinner: three to four glasses per person
Translate that to bottles by dividing total glasses by five. Twelve guests at a four hour party, drinking three glasses each, is thirty six glasses, or about seven to eight bottles. We would round to eight or nine so you are never caught watching the last bottle empty.
How should you split reds, whites, and bubbles?
A good default is a third white, a third red, and a third split between sparkling and rosé. If it is a warm Miami afternoon on a terrace, tilt toward white, rosé, and something with bubbles, because cold and refreshing wins outdoors. A cozy indoor dinner in cooler months leans redder.
Sparkling wine deserves a special mention. It is the one bottle nearly everyone will accept for a toast, so we suggest at least one bottle of something sparkling for every six guests. A dry Cava, a Crémant, or a grower Champagne all do the job beautifully and feel generous.
If you want help building a balanced mix across styles, our full range is a good place to browse for the party. You can compare bottles side by side in our complete wine selection and pick a spread that suits your crowd.
What about non-drinkers and heavier pourers?
Real parties are not made of average guests. Some people nurse one glass all night and some settle into a rhythm. Those tend to balance out, which is why the half-bottle-per-person rule holds up so well. Still, know your crowd. A group of enthusiasts will move faster, so add a bottle or two. A mixed family gathering with plenty of non-drinkers can come down a notch.
Always set out water and a non-alcoholic option or two. Guests drink more responsibly and more happily when there is something else in reach, and your wine stretches further.
Does bottle size change the plan?
It can, and in a fun way. A magnum holds two standard bottles, so it is ten glasses in one striking format. Magnums are a smart move for a big toast because they look festive on the table and mean fewer bottles to open. For a large party, a couple of magnums plus standard bottles is an elegant way to cover volume without a crowded bar.
Buying for a corporate event or client party?
The same ratios apply, but the stakes feel higher, so build in a wider buffer and lean toward crowd-pleasing, food-friendly styles that a broad room will enjoy. If you are also sending bottles to clients or staff rather than pouring on site, we handle that too. Take a look at our corporate gifting options for curated selections that arrive polished and ready.
A simple shopping checklist
- Count your adult guests and multiply by the glasses per person for your event length
- Divide total glasses by five to get bottles, then round up
- Split roughly a third white, a third red, a third sparkling and rosé
- Add at least one sparkling bottle per six guests for toasts
- Buy one or two extra bottles as insurance
Get the count right and the night runs itself.
