How Much Loose Tea Per Gallon of Iced Tea? A Simple Ratio Guide
Making a big batch of iced tea and not sure how much loose leaf to use? The short answer: about ½ cup of loose tea per gallon of water. Below is the full ratio chart for every common pitcher size, plus how to adjust it for hot brewing, cold brewing, and your own taste.
The quick answer
The standard ratio is 1.5 teaspoons of loose leaf tea per 8 oz (1 cup) of water. Scale that up and you get:
- 1 quart (32 oz): ~2 tablespoons of loose tea
- Half gallon (64 oz): ~¼ cup of loose tea
- 1 gallon (128 oz): ~½ cup of loose tea
If you only measure in spoons, a gallon works out to roughly 24 teaspoons (8 tablespoons) of loose leaf.
Why loose leaf uses a different amount than tea bags
A standard tea bag holds about 1.5–2 grams of finely cut tea. Loose leaf is usually larger, whole-leaf pieces that need a little more room to unfurl, which is why recipes call for it by the teaspoon rather than “one bag per cup.” Fruit and herbal blends with big dried pieces are lighter by volume, so a heaping measure is perfectly fine — you really can’t overdo it with a tisane.
Hot brew vs cold brew: same ratio, different time
The amount of tea stays about the same; what changes is temperature and steep time:
- Hot brew, then ice: ½ cup of tea per gallon, ~208°F water, steep 5–7 minutes, strain, cool. (Tip: brew a strong concentrate in half the water, then top with cold water and ice so it doesn’t get watery.)
- Cold brew: ½ cup of tea per gallon of cold water, refrigerate 6–8 hours or overnight, then strain. Smoother and less bitter for big batches.
Adjusting to taste
Ratios are a starting point, not a rule:
- Too weak? Add more leaf next time before you add more steep time — long steeps add bitterness, more leaf adds flavor.
- Too strong? You brewed a concentrate — just dilute the glass with extra water or ice.
- Serving over lots of ice? Bump the tea up by about 25% so it isn’t watered down as the ice melts.
A gallon, made simple
For a fruit or herbal iced tea, ½ cup of loose leaf per gallon, steeped overnight in the fridge, is a reliable, crowd-pleasing batch. Our caffeine-free mango pineapple iced tea follows this exact ratio — an 8 oz pouch makes roughly 60 glasses, so a little goes a long way.
