Bubble tea shops in China typically offer fixed sweetness levels: 全糖 (100%), 七分糖 (70%), 五分糖/半糖 (50%), 三分糖 (30%), 微糖 (slightly), 无糖 (0%). 三分糖 is the standard health-conscious choice. Pair with 少冰 (less ice) or 去冰 (no ice) when ordering.
usage
Note 三分 here means 'three-tenths' (30%), not 'three points' — the 分 system divides the full amount into 10 parts. So 七分糖 = 70%, not 7 packets.
