The leaf under everything.
Winter melon (wax gourd / ash gourd)
冬瓜 dōngguāA large, pale, waxy-skinned gourd with mild, faintly sweet, almost neutral flesh. In desserts and drinks it is not eaten raw for flavor but slow-simmered with sugar (usually brown/rock sugar or caramel) for hours until it breaks down into a fragrant amber syrup; the reduced syrup is the base for winter melon tea and is also boiled down further into solid winter melon sugar blocks (candy). Also used in savory soups.
also: wax gourd, ash gourd, white gourd
Health: TRADITIONAL/TCM: classed as cooling (寒/涼), diuretic, and used to 'clear heat', reduce phlegm/dampness and quench thirst in hot weather. Nutritionally the raw gourd is very low in calories and high in water; it contains some vitamin C and fiber. Caveat: as consumed in boba form it is dissolved into heavily sweetened syrup, so the drink is high in added sugar despite the vegetable's own low-calorie profile.
sourceWinter melon tea
冬瓜茶 dōngguā cháA classic Taiwanese sweet drink (technically caffeine-free unless blended with tea). Winter melon is peeled, seeded and boiled for several hours with brown sugar/caramel until it renders a dark, molasses-scented, honey-sweet syrup; the syrup is strained, then diluted with water or ice. Vendors add lemon, oolong or black tea, tapioca pearls, nata de coco or grass jelly. Flavor is caramel-y, mellow and refreshing.
also: winter melon punch, wintermelon drink
Health: Mostly a treat: it is essentially winter-melon-flavored sugar syrup, so it is high in added sugar. Sugar-reduced/sugar-free versions exist (marketed partly for people watching blood sugar or kidney disease). Any 'cooling' benefit is the traditional attribution of winter melon itself; the sweetness offsets health value.
sourceCheese tea
芝士奶蓋茶 zhīshì nǎigài cháTea (often green, black, or oolong, sometimes fruit tea) topped with a thick, salty-sweet foam 'cap' made from cream cheese, whipping cream, milk, and a pinch of salt. Originating in Taiwan/China street stalls and popularized by chains like HeyTea, it is meant to be sipped without a straw so the savory-creamy foam mixes with the tea on each sip. The salted-cheese cap contrasts the tea's bitterness.
also: cheese foam tea, milk cap tea, nai gai
Health: The tea base has some antioxidants/caffeine, but the cheese cap adds cream, cheese, and sugar — treat it as a dessert drink.
sourceBlack tea
紅茶 hóngchá (lit. 'red tea')Fully oxidized tea leaves that brew a dark amber-red liquor with a bold, malty, slightly astringent flavor. It is the classic backbone of Taiwanese milk tea because its strength stands up to milk, creamer and sugar without being washed out. Most 'original milk tea' or 'pearl milk tea' uses a black tea base.
also: red tea; the default 'milk tea' base
Health: Highest-caffeine of the common bases, roughly 40-70 mg per typical 16-20 oz milk tea depending on brew strength. Contains theaflavins/antioxidants, but the sugar and creamer usually dominate the health profile of the finished drink.
sourceAssam black tea
阿薩姆紅茶 āsàmǔ hóngcháA specific single-origin black tea from the Assam region of India, prized in boba for its thick body, deep reddish-brown color and strong malty note. Many shops market their standard milk tea specifically as 'Assam milk tea' because the robust leaf holds flavor against dairy and ice better than lighter blends.
also: Assam milk tea
Health: Caffeine content is on the higher end like other black teas (~40-70 mg per serving). Naturally rich in tannins; nutritionally similar to generic black tea before add-ins.
sourceGreen tea
綠茶 lǜcháUnoxidized tea with a light green-yellow liquor and a fresh, grassy, sometimes vegetal or floral taste. Used as a lighter, more delicate base for milk teas and especially for fruit teas, where its subtle flavor lets fruit shine. Common in green milk tea and many fruit-green blends.
also: green milk tea base
Health: Lower caffeine than black tea, roughly 20-45 mg per serving. Rich in catechins (notably EGCG) and antioxidants; still, added sugar in a boba drink offsets much of the 'healthy tea' benefit.
sourceOolong tea
烏龍茶 wūlóng chá (lit. 'black dragon')A partially oxidized tea sitting between green and black, with a wide flavor range from floral and creamy to toasty and roasted depending on oxidation and roast. In boba it gives a fragrant, smooth base for milk tea and is popular on its own with just a splash of milk or as an unsweetened tea.
also: wulong
Health: Moderate caffeine, roughly 30-50 mg per serving (between green and black). Contains polyphenols and antioxidants; often chosen by people wanting flavor with less astringency than black tea.
sourceJasmine tea
茉莉花茶 / 茉莉綠茶 mòlì huā chá / mòlì lǜcháUsually a green tea (sometimes a light oolong) that has been scented by layering the leaves with fresh jasmine blossoms, giving a sweet, perfumed, floral aroma. A very common boba base, especially for jasmine milk tea and fruit teas, valued for its fragrance more than body.
also: jasmine green tea
Health: Caffeine tracks its base leaf, typically green-tea range (~20-45 mg). The jasmine adds aroma, not caffeine. Same antioxidant profile as the underlying green tea.
sourceEarl Grey tea
伯爵茶 bójué chá (伯爵 = 'earl/count')A black tea flavored with oil of bergamot (a citrus), giving a distinctive fragrant, citrusy-floral aroma over a black-tea backbone. In boba it makes a popular aromatic milk tea (often called 'Earl Grey milk tea' or, with cheese foam, a signature shop drink).
also: bergamot black tea
Health: Black-tea caffeine level (~40-70 mg). Bergamot is flavoring only. Note: in very large habitual quantities bergamot has rare interactions, but boba serving levels are not a practical concern.
sourceThai tea
泰式奶茶 tài shì nǎichá ('Thai-style milk tea')A strongly brewed black tea (traditionally spiced and often colored bright orange with added coloring) sweetened heavily and mixed with condensed and/or evaporated milk. It has a rich, sweet, creamy, almost vanilla-caramel taste and a signature orange hue. Extremely popular as a boba flavor.
also: Thai iced tea, cha yen
Health: One of the sweeter, higher-calorie boba options because it is built on condensed milk and lots of sugar. Black-tea caffeine (~40-70 mg). The orange color is typically artificial food coloring.
sourceMatcha
抹茶 mǒcháFinely stone-ground powder of shade-grown green tea leaves. Because you drink the whole leaf as suspended powder, it has an intense, creamy, vegetal, slightly bitter flavor and vivid green color. In boba it is whisked into milk for matcha latte / matcha milk tea, and sometimes layered with other bases.
also: stone-ground green tea powder
Health: Since you consume the whole leaf, matcha delivers more caffeine per gram than steeped green tea (a boba matcha drink can run ~40-70 mg). Also higher in catechins and contains L-theanine, which many describe as giving a calmer, steadier energy. Watch for pre-sweetened matcha powders high in added sugar.
sourceHojicha (roasted green tea)
焙茶 / 烘焙茶 Japanese: hōjicha; Mandarin 焙茶 bèichá / 烘焙茶 hōngbèi cháA Japanese green tea that is roasted over high heat, turning the leaves reddish-brown and producing a warm, toasty, nutty, caramel-like flavor with almost no bitterness or grassiness. In boba it makes a distinctive amber-brown roasted milk tea / hojicha latte.
also: houjicha, roasted tea
Health: Notably low caffeine — roasting drives off much of it, so hojicha is often the go-to base for a lighter-caffeine or evening boba drink. Low in astringency and easy on the stomach.
sourcePu-erh tea
普洱茶 pǔ'ěr cháA fermented/aged dark tea from Yunnan, China, with a deep earthy, woody, sometimes mellow-sweet flavor and a very dark liquor. Less common in mainstream chains but used in specialty milk teas (e.g., pu-erh milk tea) for its smooth, rich, distinctive earthiness that pairs well with milk.
also: pu'er, fermented dark tea
Health: Moderate to fairly high caffeine (varies with brew, roughly 30-70 mg). Traditionally associated in Chinese culture with digestion after fatty meals, though clinical evidence is limited. Aged/microbially fermented, so quality of sourcing matters.
sourceMilk tea vs. fruit tea (the split)
奶茶 vs 水果茶 nǎichá vs shuǐguǒ cháThe two main families of boba drinks. Milk tea (奶茶) is a tea base blended with milk or creamer (and usually sugar) for a creamy, dessert-like drink. Fruit tea (水果茶) is a tea base — usually green, jasmine or light oolong — mixed with fruit, fruit purée/juice or syrup and no dairy, giving a lighter, brighter, more refreshing tart-sweet drink often served with fruit bits or popping boba.
also: milk tea 奶茶 / fruit tea 水果茶 (also called 水果冰茶 fruit iced tea)
Health: Fruit tea is typically lower in fat and calories than milk tea (no dairy/creamer) and can taste 'lighter,' but it is not automatically healthy — many fruit teas rely on sugar syrup or sweetened purée, so a full-sugar fruit tea can rival a milk tea in sugar. Milk tea adds dairy/creamer fat and, with brown sugar or condensed milk, the highest sugar loads. Choosing dairy vs. no-dairy is separate from choosing sugar level.
sourceSweetness levels & ice culture
甜度與冰塊 (半糖 / 微糖 / 少冰 / 去冰) tiándù yǔ bīngkuài; bàntáng / wēitáng / shǎobīng / qùbīngA defining part of Taiwanese boba ordering: you customize sweetness and ice. Common sugar tiers are 正常糖/全糖 (100%, full), 少糖 shǎotáng (~70%), 半糖 bàntáng (~50%, 'half sugar'), 微糖 wēitáng (~30%, 'slight sugar') and 無糖 wútáng (0%). Ice tiers run 正常冰/多冰 (regular/extra), 少冰 shǎobīng (less ice), 去冰 qùbīng (no ice) and 常溫/溫 (room temp/warm). Ordering 'half sugar, less ice' (半糖少冰) is the classic move for a balanced, less-diluted drink.
also: sugar level, ice level; 正常糖 full sugar, 少糖 less sugar, 半糖 half, 微糖 slight, 無糖 none
Health: This is the single most effective lever for making boba healthier: dialing sugar to half, slight or none can dramatically cut the added-sugar and calorie load of a drink. Note that 'less ice' means less dilution, so the same syrup is concentrated in less liquid — some regulars pair less ice with a lower sugar level. Pearls themselves also add ~100-150+ calories of starch and sugar regardless of the sugar setting.
