How to Make Lemonade for a Crowd: Batch Ratios, Sugar and Scaling Math

Lemonade for fifty people is not the same job as lemonade for four. The recipe barely changes; what changes is how you measure, how you dissolve the sugar and how you keep two hundred cups tasting identical from the first pour to the last. This is the version used on a service line, with the math done for you.

The ratio

The neutral starting point is 4 parts water to 1 part lemon juice to 1 part sugar. The Takeout puts that at "10 cups of water, 2 ½ cups of sugar, and 2 ½ cups of lemon juice," and notes that recipes range from a lighter 6-1-1 to a sharper 3-1-1. For service, pick one ratio and write it on the wall. Consistency sells more than perfection.

How much to make

Plan by the cup, not the gallon. One gallon is roughly ten 12 oz cups once ice takes up space. At a summer event, most planners work on one to two cups per guest, leaning high in heat or when lemonade is the only non-alcoholic option.

Those figures use the standard 4-1-1 ratio, count 1.5 cups per guest, and assume sugar at roughly 1.6 cups per pound. Round up: leftover concentrate keeps, and running out at 2 p.m. does not.

Scaled method

1. Weigh, don't scoop. Above about five gallons, measure sugar by weight and juice by volume. Scooping sugar into a bucket is where batches drift apart.
2. Dissolve the sugar in the juice first. Stir superfine sugar straight into room-temperature juice until the grit is gone. No heat, no simple syrup pot.
3. Add cold water last. Adding water first makes the sugar take twice as long to go in.
4. Taste at full dilution. Concentrate always tastes right; the finished cup is what matters.
5. Chill the batch, then ice the cup. Ice in the urn melts and waters down the last third of the day.
6. Hold and label. Keep batches cold and dated, and stir before each refill.

Which base to build from

Frozen purée. Boiron lemon purée thaws into a base with the same acidity every time, which is the main reason cafés and caterers use it instead of fresh lemons. Thaw in the cooler overnight, never at room temperature.

Bottled juice. Squeez-eez lemon juice pours fast on a line and needs no prep. Best for stands doing volume.

Juice powder. Lemon juice powder premixes dry with sugar, so a festival booth can carry the whole drink in one sack and add water on site.

All three are in the Lemonade & Beverage Station collection, along with sugars and garnish.

Flavored variations that sell

Because the purées carry their own sweetness, cut the sugar slightly when you flavor a batch, then taste. For a bar or café that wants flavor without thawing anything, cocktail syrups pour straight into the cup — mint, matcha lime and salted grapefruit all work over lemonade.

Finishing and serving

Rim the cup with sanding sugar for an event, skewer candied lemon cubes for a photo-worthy garnish, or drop in frozen citrus zest for aroma. Keep the garnish station separate from the pour station so the line keeps moving.

Batch-ahead and storage

Concentrate at 1-1-1 holds well in a cooler for several days and cuts your on-site work to adding water and ice. Finished lemonade is best the same day; acidity keeps it safe far longer than it keeps it tasting bright. Label every container with the batch time, and never top up an old batch with a fresh one — start clean so the flavor doesn't drift.
