How Much Alcohol for Open Bar Wedding?
The question on every couple’s mind when planning their open bar wedding is: How much alcohol should we buy? The answer depends on various factors, such as the number of guests, their drinking preferences, the duration of the event, and the type of alcohol you plan to serve. To help you calculate the perfect amount, here’s a breakdown of the key considerations:
1. Number of Guests
The first step in determining how much alcohol you’ll need is estimating the number of guests attending your wedding. Take into account both daytime and evening guests, as well as any fluctuations you anticipate during the event. A good rule of thumb is to assume that each adult guest will consume approximately two drinks in the first hour and one drink per subsequent hour.
2. Drinking Preferences
Consider the drinking preferences of your guests. Are they predominantly wine enthusiasts, cocktail connoisseurs, or beer lovers? Take a poll or consult with your close friends and family to gauge their preferences. This will help you allocate your alcohol budget more effectively.
3. Duration of the Event
Next, consider the duration of your wedding celebration. Is it a short and sweet affair or an all-night extravaganza? The longer the event, the more time your guests will have to enjoy the drinks. A general estimate is to plan for a three- to five-hour reception, including cocktail hour and dancing.
4. Type of Alcohol
The type of alcohol you plan to serve also plays a significant role in determining quantities. Here’s a breakdown of the typical amounts needed for various drink options:
a) Wine
For wine, calculate approximately five glasses per bottle. If you have a mix of red and white, assume a 50-50 split. As a rough estimate, plan for half a bottle of wine per person for the entire event.
b) Beer
When it comes to beer, a good guideline is to assume two to three drinks per person per hour. Take into account the variety of beer styles you plan to offer, including light, craft, and non-alcoholic options.
c) Spirits
Spirits like whiskey, vodka, gin, and rum can be used to create a wide range of cocktails. On average, plan for one to two drinks per person per hour, considering that not all guests will opt for mixed drinks. Keep in mind that you’ll also need mixers, such as tonic water, soda, and fruit juices.
d) Champagne and Sparkling Wine
If you’re including a toast with champagne or sparkling wine, allocate approximately one glass per guest. Factor in the time it takes to pour and distribute the glasses to ensure everyone can participate in the celebratory moment.
5. Additional Factors
Other factors to consider when calculating the amount of alcohol for your open bar wedding include the weather (as guests may consume more during hot summer months), any unforeseen delays or extensions to the event, and whether you have any specialty or signature cocktails that require specific ingredients.
FAQs about How Much Alcohol for Open Bar Wedding
To further assist you in planning the alcohol for your open bar wedding, here are some frequently asked questions along with their answers:
FAQ 1: Should I offer a full open bar or limited options?
It depends on your budget and the preferences of your guests. A full open bar provides a wide range of drink options, but it can be more expensive. Limited options, such as a signature cocktail menu or beer and wine only, can help control costs while still offering a variety of choices.
FAQ 2: Can I provide a cash bar instead?
While some couples opt for a cash bar to reduce expenses, it’s generally considered more hospitable to offer an open bar. Your guests will appreciate not having to worry about bringing cash or credit cards, and it contributes to the celebratory atmosphere of the wedding.
FAQ 3: What if I have guests who don’t drink alcohol?
It’s essential to accommodate guests who prefer non-alcoholic beverages. Offer a selection of mocktails, soft drinks, sparkling water, and juices to ensure there are enticing options for everyone.
FAQ 4: Can I ask my venue or caterer for recommendations?
Absolutely! The professionals at your venue or caterer have experience in planning weddings and can provide valuable insights into how much alcohol you’ll need. They can also guide you on popular drink choices and help you calculate quantities based on their expertise.
FAQ 5: Is it better to overestimate or underestimate the alcohol quantities?
It’s generally safer to slightly overestimate rather than underestimate the amount of alcohol you’ll need. Running out of drinks during the event can be disappointing for your guests, whereas having some leftovers can be consumed later or used for future celebrations.
FAQ 6: How can I calculate the quantities more accurately?
Consider using an online alcohol calculator or consulting a professional wedding planner. These resources can provide you with precise calculations based on the number of guests, duration of the event, and your specific drink choices.
Conclusion

Planning an open bar wedding involves thoughtful consideration of various factors to ensure your guests have an enjoyable and well-stocked celebration. By estimating the number of guests, considering drinking preferences, factoring in the duration of the event, and choosing the right types of alcohol, you can strike a perfect balance and create a memorable experience for everyone.
Remember, it’s always better to err on the side of caution and slightly overestimate the quantities to avoid any potential shortages. Communicate with your venue, caterer, or wedding planner for expert advice and recommendations based on their experience.
Cheers to a fantastic wedding filled with joy, love, and just the right amount of alcohol to keep the party going!
