Grass jelly is a soft black herbal jelly used in bubble tea, shaved ice, soy milk drinks, and Asian desserts. In boba, it adds a smooth, lightly bitter bite instead of the chewiness of tapioca pearls. It works best with milk tea, roasted tea, coffee milk tea, and lower-sugar fruit tea.
Grass Jelly in Bubble Tea: Calories, Nutrition & Taste Nutrition Facts
Per 8 oz (240ml) serving
What is grass jelly?
Grass jelly is made from mesona, a plant in the mint family. The leaves and stalks are cooked, strained, and set into a dark jelly that can be cut into cubes or strips. You may also see it called black grass jelly, herbal jelly, leaf jelly, cincau, or xian cao.
In bubble tea shops, grass jelly is usually served chilled from a tub or scoop pan. The jelly itself is not very sweet. Most of the sweetness comes from syrup, brown sugar, creamer, or the drink base around it.
Grass jelly calories
The nutrition table on this page lists grass jelly at 60 calories per 8-ounce serving in the Bubble Teas ingredient dataset. A real boba topping scoop is often smaller than that, closer to 1-2 ounces, but shops vary.
| Serving style | Calorie note |
|---|---|
| Small scoop of plain grass jelly | Usually a lighter topping than tapioca pearls or pudding |
| Extra grass jelly in syrup | Can add more sugar than the jelly itself suggests |
| Grass jelly milk tea | The milk, creamer, and drink sugar do most of the calorie work |
| Grass jelly plus brown sugar | More of a dessert drink than a light tea order |
If calories matter, start with the drink sweetness level. Asking for 25-50% sugar usually changes the cup more than swapping one jelly topping for another.
Grass jelly nutrition
Grass jelly is mostly water and carbohydrate, with small amounts of protein and minerals in some nutrition databases. It is usually fat-free and caffeine-free on its own. That does not make it a high-nutrition food, but it can be a lighter topping if the shop is not storing it in heavy syrup.
| Nutrient question | Practical answer |
|---|---|
| Is grass jelly high in calories? | Plain grass jelly is usually modest in calories, but syrup and milk tea can raise the total quickly. |
| Does grass jelly have caffeine? | The jelly does not. Tea or coffee in the drink base can still add caffeine. |
| Is grass jelly high in sugar? | Plain jelly is mild, but packaged and shop versions may sit in sweet syrup. |
| Is grass jelly filling? | It adds volume and texture, but it is not a meaningful protein or fiber source. |
The safest nutrition check is the packaged label or the shop’s nutrition page. If neither is available, treat grass jelly as a sweet topping and adjust the drink sugar.
Is grass jelly healthy?
Grass jelly is fine as an occasional bubble tea topping, especially if you like herbal flavors and want something softer than tapioca pearls. It is not a cure-all food. Traditional cooling claims are part of how grass jelly is discussed in several Asian food cultures, but a boba order still depends on sugar, serving size, and the drink base.
For a lighter order, pair grass jelly with unsweetened black tea, roasted oolong, jasmine tea, or soy milk at reduced sugar. For a richer order, use it with milk tea or coffee milk tea and keep the topping count low.
What does grass jelly taste like?
Grass jelly tastes mildly herbal, earthy, and a little bitter. The texture is smooth and slippery, closer to soft jelly than chewy boba. Some people like it because it makes sweet milk tea taste less flat. Others find the herbal edge too strong in fruit drinks.
It is a better match for roasted, creamy, or coffee-like drinks than for bright citrus drinks.
Best drinks with grass jelly
| Drink | Why it works |
|---|---|
| Black milk tea | Classic pairing. The creamy tea softens the herbal note. |
| Roasted oolong milk tea | Roasty flavor makes grass jelly taste intentional instead of bitter. |
| Coffee milk tea | The jelly reads almost like a soft coffee dessert topping. |
| Soy milk tea | Smooth, mild, and good if you want a dairy-free base. |
| Brown sugar milk tea | Rich and dessert-like, but best with less added sugar. |
| Winter melon tea | Sweet, herbal, and refreshing if ordered at lower sugar. |
For fruit tea, choose gentle bases such as peach oolong or honey green tea. Lemon-heavy drinks can make grass jelly taste sharper.
Grass jelly vs other boba toppings
| Topping | Texture | Best use |
|---|---|---|
| Grass jelly | Soft, slippery cubes or strips | Milk tea, roasted tea, coffee milk tea, soy milk |
| Tapioca pearls | Chewy starch pearls | Classic milk tea and brown sugar drinks |
| Lychee jelly | Fruity soft jelly | Jasmine tea, green tea, and lighter fruit teas |
| Coconut jelly | Firmer jelly chew | Tropical fruit tea and canned bubble tea |
| Pudding | Custardy and soft | Milk tea and dessert drinks |
Choose grass jelly when you want a softer topping with an herbal edge. Choose lychee or coconut jelly when you want a sweeter fruit note.
