Planning a big event or wedding can seem daunting, especially when it comes to making sure you’ve got enough drink options for everyone.

If your guest list is around 100 attendees, a good estimate is to have about 70 bottles of wine on hand.

This calculation stems from the Best Wedding Alcohol Calculator’s recommendation and allows for each guest to enjoy several glasses throughout the course of the event, given that each bottle typically serves up to five glasses.

Stick with this quantity even if your crowd isn’t composed entirely of wine lovers – it factors in those who may want just one glass or choose wine over other beverage options available.

With an array of varietals like Chardonnay, Cabernet Sauvignon, and Pinot Noir stocked up in advance, you’ll have all bases covered and can put aside worries about running out midway through festivities.


For a party with 100 guests, it is recommended to have approximately 175 bottles of beer.

This amount ensures that there will be enough for everyone to enjoy throughout the event. It’s important to consider the preferences of your guests when selecting the type and brand of beer.

Opting for a variety of flavors and styles can cater to different tastes and enhance the overall drinking experience. Remember, having an ample supply of beer will contribute to a fun and lively atmosphere at your gathering.

Factors to Consider When Calculating Alcohol Amounts

Duration of the event

The duration of the event is an important factor to consider when calculating the amount of beer and wine needed for 100 guests. For a four-hour reception, it is recommended to plan for approximately 400 drinks in total.

This includes about 160 beers, which could be equivalent to seven cases or 170 individual bottles. Additionally, you would need around 144 glasses of wine (equivalent to about 29 bottles) and enough for 96 individual cocktails.

It’s crucial to estimate your alcohol needs accurately based on the length of your event to ensure that all your guests have plenty of drinks throughout the celebration.

Guest preferences

Understanding the preferences of your guests is crucial when calculating the amount of beer and wine needed for a party with 100 attendees.

It’s important to consider their tastes and preferences, whether they lean towards wine or prefer beer.

By taking into account guest preferences, you can ensure that you have the right balance of alcohol to cater to everyone’s tastes and make your event more enjoyable for all.

Other beverage options

When planning the beverages for your event, it’s important to consider other options besides beer and wine.

Here are some additional beverage options that you may want to include:

  • Spirits: Adding a selection of spirits to your bar menu can give guests more variety and allow them to enjoy different types of cocktails. Consider including popular spirits such as vodka, rum, whiskey, tequila, and gin. Remember to have mixers like soda, tonic water, and juices available as well.
  • Champagne: To add a touch of elegance to your event, consider including champagne or sparkling wine. This can be served as a welcome drink or during toasts and speeches. It’s always a good idea to have both dry and sweet options available to cater to different preferences.
  • Signature Cocktails: Creating a few signature cocktails for your event adds a personal touch and allows guests to try something unique. Choose cocktails that fit the theme or style of your event and provide a refreshing option for those who may not prefer beer or wine.
  • Non-Alcoholic Beverages: It’s important to provide options for guests who do not consume alcohol or prefer non-alcoholic drinks. Offer a range of non-alcoholic beverages such as mocktails, sodas, juices, infused waters, or even specialty teas or coffees.
  • Water: Always make sure there is an ample supply of water available throughout the event. Hydration is essential for everyone attending, especially if alcohol is being consumed.

Tips for Customizing Your Alcohol List

Consider the time of day, season, and climate

The time of day, season, and climate are important factors to consider when planning the amount of beer and wine needed for 100 guests. For example, if you’re hosting an afternoon event during the summer months, your guests may prefer lighter and more refreshing drinks like white wine or a crisp lager.

On the other hand, if you’re having an evening affair in the winter, richer red wines and darker beers might be more suitable.

Additionally, keep in mind that extreme temperatures can affect consumption rates – guests may drink less in hot weather but more in colder conditions.

By considering these variables, you can ensure your alcohol selection matches the atmosphere and preferences of your guests while providing a delightful drinking experience tailored to the specific occasion.

Analyze the guest profile

Understanding your guest profile is crucial when customizing your alcohol list for an event. Take into consideration the age rangepreferences, and drinking habits of your guests. Consider whether they are predominantly beer drinkers or wine enthusiasts.

It’s also important to note any specific dietary restrictions or preferences, such as gluten-free or vegan options.

By analyzing the guest profile, you can ensure that you provide a selection of beverages that will cater to their tastes and preferences, making the event more enjoyable for everyone involved.

Match the alcohol selection to the wedding style and venue type

When it comes to planning the alcohol selection for your wedding, it’s important to consider the style and venue type. The drinks you offer should complement the overall atmosphere of your special day.

For a formal black-tie affair, you might opt for a variety of high-end wine options and perhaps even a signature cocktail that matches your theme. On the other hand, if you’re having a more relaxed outdoor wedding, craft beers and refreshing wines would be a great fit.

By matching the alcohol selection to your wedding style and venue type, you can ensure that your guests will have an enjoyable experience as they sip on their preferred beverages throughout the celebration.

According to Eventbrite’s beverage calculator recommendations from our important facts section, for 80 heavy drinkers at your wedding reception, you may want to aim for approximately 32 bottles of wine and 144 beers.

Wedding Bar Shopping Tips

Understanding the quantity of drinks in a bottle or case

Beer and wine are typically sold in varying quantities, so it’s important to understand how many drinks you can expect from a bottle or case. On average, a standard 750ml bottle of wine provides around five glasses of wine.

This means that for 100 guests, you would need approximately 70 bottles of wine (equivalent to 350 glasses). When it comes to beer, a case usually contains around 24 bottles or cans. With about four beers per person as the general guideline, for 100 guests you would need approximately seven cases of beer (168 individual bottles).

By understanding these quantities, you can accurately estimate the amount of alcohol needed to keep your guests happy throughout your event without overbuying or running out prematurely.

Determining where to buy alcohol

To ensure you have enough beer and wine for your 100 guests, it’s important to know where to buy alcohol. One option is to go directly to a local liquor store or supermarket that carries a wide variety of wines and beers.

This allows you to browse different options and compare prices. Another option is to consider purchasing alcohol online from specialized retailers or wholesalers. This can be convenient if you’re looking for specific brands or have a larger budget.

Additionally, some venues may offer the option of providing their own alcohol, but this may come with additional fees or restrictions. Regardless of where you choose to buy your alcohol, make sure to check for any special promotions or bulk discounts that can help you save money on your purchase.

Managing leftovers and considerations for hiring a bartender

Managing leftovers and considerations for hiring a bartender:

  1. Plan ahead: When estimating your alcohol quantities, it’s important to take into account the possibility of leftovers. Consider how many guests are likely to consume alcohol and adjust your quantities accordingly.
  2. Storage options: If you end up with extra beer and wine after the event, make sure you have proper storage options available. Keep in mind that wine can be stored for longer periods compared to beer, so consider investing in a wine refrigerator or cellar if you frequently host events.
  3. Donate or return: If you have unopened bottles of alcohol left over, consider donating them to local charities or returning them to the store (if possible). This way, you can minimize waste and support those in need.
  4. Repurpose: Leftover beer and wine can be used in various culinary preparations. Beer can be used for cooking stews or marinating meat, while wine can be used for sauces or even making sangria.
  5. Considerations for hiring a bartender: Hiring a professional bartender can help ensure that your guests are served properly and responsibly. A bartender can also assist with managing inventory throughout the event.
  6. Licensing requirements: Before hiring a bartender, make sure they have the necessary permits and licenses required by your state or country’s alcohol regulations.
  7. Experience and expertise: Look for bartenders who have experience working at events similar in size to yours. They should be familiar with different types of beer and wine and know how to serve them correctly.
  8. Communication is key: Clearly communicate your expectations regarding alcohol service with the bartender before the event. Discuss specific drink preferences, quantities needed, and any special instructions regarding serving sizes.
  9. Responsible service: Ensure that your hired bartender has been trained in responsible alcohol service techniques such as checking IDs, identifying intoxicated individuals, and cutting off service when necessary.
  10. Bartender-to-guest ratio: Depending on the size and complexity of your event, you may need to hire multiple bartenders. Consider the number of guests and the desired level of service when determining the appropriate ratio.


In conclusion, when planning for an event with 100 guests, it’s important to estimate the amount of beer and wine needed carefully.

By considering factors like duration, guest preferences, and other beverage options, you can create a customized alcohol list that suits your specific event.

Remember to analyze the guest profile and match the alcohol selection to the wedding style and venue type. With these tips in mind, you’ll be well-prepared to stock your bar and ensure everyone has a great time!
