Wine Quantity Calculator

For 50 guests at a typical 3-hour event, plan for roughly 38 to 45 bottles of wine. The exact count depends on the style of event and how heavily guests drink. A cocktail party tends toward the higher end because guests circulate and drink more, while a seated dinner is more moderate. Use our calculator above to get a precise breakdown by wine type.

A standard 750ml bottle of wine yields approximately 5 glasses when poured at the standard serving size of 150ml (about 5 ounces). If you pour more generously you may only get 4 glasses, and with more conservative pours at a tasting event you could stretch it to 6. Our calculator uses the industry-standard 5 glasses per bottle.

For a 4-hour party, multiply the number of guests by 4 hours and then by the typical consumption rate of 1 to 1.5 glasses per person per hour. For example, 30 guests at a cocktail party would need about 180 glasses, or around 36 bottles. Our calculator factors in event type so you get accurate results for cocktail parties, dinners, and more.

A common wedding ratio is 30% red, 30% white, and 40% sparkling, reflecting the emphasis on toasts and celebratory bubbles. However, this can shift depending on the season, menu, and your guests' preferences. Summer weddings tend toward more white and sparkling, while winter weddings lean heavier on reds. Adjust the event type in our calculator to see specific recommendations.

For 100 guests at a 3-hour event, you will typically need between 6 and 8 cases of wine (72 to 96 bottles), depending on the type of event. A standard case contains 12 bottles. Our calculator rounds up to whole cases so you never run short. It is always wise to order a case or two extra to account for heavier-than-expected consumption.
