Coffee for a Crowd takes more planning than brewing one cup. Use the right equipment, fresh beans, and consistent ratios.

This guide explains Coffee for a Crowd for gatherings of 5 to 100 people. Learn the best methods, ratios, and serving tips.

How Much Coffee Do You Need?

Plan on one or two 6-ounce cups per guest. Use these amounts as a starting point.

  • 5 people: 30 to 60 ounces. Use 2 to 4 ounces (55 to 110 grams) of coffee.
  • 10 people: 60 to 120 ounces. Use 4 to 8 ounces (110 to 225 grams).
  • 20 people: 120 to 240 ounces. Use 8 to 16 ounces (225 to 450 grams). One 12-ounce bag serves about 20 cups.
  • 50 people: 300 to 600 ounces. A bulk coffee collection bag works well.
  • 100 people: 600 to 1,200 ounces. Plan on two or three five-pound bags.

Start with a 1:16 coffee-to-water ratio. Adjust stronger or lighter to match your guests' preferences.

Small Gatherings (5 to 10 People)

Coffee for a Crowd starts with the right brewer. A large French press or 10-cup drip machine works well.

A 34-ounce French press brews about five cups. Two batches serve up to 10 guests.

For detailed instructions, read our French press brewing method guide.

A Chemex or large pour-over carafe also works well for smaller gatherings.

One 12-ounce bag from our premium coffee collection is usually enough. Grind fresh whenever possible.

Medium Gatherings (10 to 30 People)

Coffee for a Crowd is easier with a large drip brewer and thermal carafes.

Brew in batches and transfer coffee to pre-heated thermal carafes. They keep coffee hot without overcooking it.

Prepare two or three batches before guests arrive. Brew more as needed during the event.

Use one or two 12-ounce bags, or choose our bulk coffee collection for larger groups.

Offer cold brew alongside hot coffee for extra variety. It is a popular option for iced coffee drinkers.

See our cold brew how-to guide for step-by-step instructions.

Large Gatherings (30 to 100 People)

Coffee for a Crowd is easiest with a coffee urn or commercial brewer. These brewers handle large batches efficiently.

Clean the urn before every use. Use a coarse grind and measure coffee by weight.

Turn off the heat after brewing if possible. Remove the grounds immediately to reduce bitterness.

A five-pound bag serves about 50 guests. Plan on two or three bags for 100 people.

Single serve pods work well as a secondary station. They are less practical for large groups.

Browse our single serve coffee pods for quick, individual servings.
