We sampled four versions of store-bought lemonade to find the tastiest. Here's how they ranked.

1. Frozen Concentrate
Testers chose frozen concentrate as the all-around best, calling it "fresh" and "authentic." One said, "It makes me feel like a kid again!"

RS pick: Minute Maid Premium Lemonade frozen concentrate.

Cost (per 8-ounce serving): about 22 cents.

2. Dry Mix
This was an easy second. Testers enjoyed its "even consistency."

RS pick: Country Time Lemonade Flavor Drink Mix.

Cost: about 13 cents.

3. Shelf-Stable Ready-to-Drink
This low-maintenance version did not fare well. Testers called it "artificial" and said it "left a bad aftertaste."

Cost: about 82 cents.

4. Refrigerated Ready-to-Drink

This ranked last — "syrupy," "thick," and "too sweet."

Cost: about 31 cents.
