How big of a keg should you get for 12 person party if people will be having more then 3 drinks?

Assumptions:

* Average Drink Size: Let's assume people drink 12oz (standard beer) per serving.

* Drinks Per Person: You mentioned more than 3 drinks per person. Let's go with an average of 4 drinks each.

Calculations:

1. Total Drinks: 12 people x 4 drinks/person = 48 drinks

2. Total Ounces: 48 drinks x 12 oz/drink = 576 ounces

3. Keg Size (Gallons): 576 ounces / 128 ounces/gallon = 4.5 gallons

Keg Recommendation:

Based on these calculations, a 4.5-gallon keg would be a good size for your 12-person party, assuming everyone drinks around 4 beers.

Important Notes:

* Drink Preferences: If you know your guests prefer different drinks (ciders, stouts, etc.), consider that some might drink more or less than others.

* Party Length: A longer party might mean more drinks per person.

* Keg Sizes: Kegs come in standard sizes (half barrels, quarter barrels, etc.) so you might need to go up to the next closest size (5 gallons) to find a keg that fits your needs.

* Leftovers: It's always better to have a bit extra than to run out!

For a more accurate estimate, consider:

* Your guests' drinking habits: Do they tend to drink a lot or a little?

* The party atmosphere: Will it be a casual hangout or a more energetic event?

Remember, these are just estimates. It's better to be prepared with a little extra than to run out of beer!
