How Many Gallons of Tea for 100 People? (The Easy Answer)

Catering tea for 100 guests? Here's exactly how many gallons of sweet tea, unsweet tea, and iced tea to plan — plus a guest-count cheat sheet from Atlanta's lemonade caterer.

The Short Answer

For 100 people at a 2–3 hour event, plan on 8–10 gallons of iced tea total. That covers roughly 1.5 cups per guest, which is the standard catering rule for any non-alcoholic beverage at a meal-anchored event.

If your event runs longer than 3 hours, is outdoors in summer heat, or doesn't have other drink options, bump it to 12 gallons for 100 people.

Here's the breakdown:

  • 1 gallon of tea = roughly 16 standard 8-oz cups
  • 100 guests × 1.5 cups each = 150 cups needed
  • 150 cups ÷ 16 cups per gallon = ~9.4 gallons

Round up to 10 gallons so you don't run out at hour two.

Sweet Tea vs. Unsweet — How to Split

In the South, the standard split for 100 guests is 70% sweet, 30% unsweet. Outside the South, flip it: 40% sweet, 60% unsweet. So for 10 gallons total at an Atlanta event:

  • 7 gallons of sweet tea
  • 3 gallons of unsweet tea (with a lemon wedge garnish — guests can sweeten themselves)

If you're serving both sweet and unsweet, label the dispensers clearly. Mislabeling sweet tea as unsweet is the #1 caterer complaint we hear at Atlanta receptions.

How Much Ice Do You Need?

Ice gets forgotten until it's gone. Plan 1 lb of ice per guest for an iced-tea station — so 100 guests = 100 lbs of ice. That sounds like a lot, but ice melts faster than guests drink at outdoor events. A 10 lb bag covers about 10 guests.

Brewing 10 Gallons of Tea — The Quick Math

If you're brewing yourself rather than buying pre-made:

  • Loose tea: 1 oz of loose-leaf black tea per gallon → 10 oz for 10 gallons
  • Family-size tea bags: 1 bag per gallon → 10 bags for 10 gallons
  • Regular tea bags: 6–8 bags per gallon → 60–80 bags for 10 gallons
  • Sugar for sweet tea: 1 cup per gallon (Southern-style) → 7 cups for 7 gallons of sweet

Brew with hot water, steep 5 minutes, dilute with cold water and ice. Don't over-steep — bitter tea ruins the day.

When You're Better Off Hiring a Caterer

For 100+ guests, brewing 10 gallons of tea takes about 3 hours of active work — plus you need 4–5 large dispensers, 100 lbs of ice, cups, lemons, a sweetener station, and someone to refill it all during the event. By the time you've bought the equipment and prepped the tea, you've spent the morning of your own party in the kitchen.

Most Atlanta hosts running a 100-person reunion, wedding, or corporate event hire a beverage caterer for $400–$800 total. That covers tea, ice, dispensers, cups, lemon, setup, and breakdown — and the host gets to actually enjoy the event.

What About Lemonade Instead?

The same 1.5 cups-per-guest math works for any non-alcoholic drink. Pairs especially well at family reunions, weddings, and corporate events where you want a drink station that doubles as decor.

TL;DR

For 100 people, plan on 10 gallons of iced tea (7 sweet + 3 unsweet), 100 lbs of ice, and a couple of lemon wedges per dispenser. Bump everything 20% for hot outdoor events or anything running past 3 hours. And if running a tea station yourself sounds like a part-time job — it kind of is.
