About the Crisp Grape Boom
HEYTEA sells the Crisp Grape Boom at $9.49 for a regular cup, and that cup carries 210 calories. Green grapes go in crushed rather than juiced, so pulp stays suspended through a jasmine green tea base. You end up chewing your fruit tea slightly, and that is the whole point of the Boom naming.
Three things are doing the work in your cup. The jasmine green tea underneath is floral and light rather than tannic, so it sits behind the fruit instead of fighting it. The grape pulp carries most of the sweetness, and it drifts toward the bottom as the ice melts, which is why your last few sips taste stronger than your first. Ice fills the rest, so asking for less of it gets you more drink for the same $9.49.
To me this lands much closer to a fresh grape than to grape candy. There is a green, faintly tart edge off the skins that survives the shaking, and the finish stays clean instead of turning syrupy. Sugar level changes the drink completely across its range. At around half sugar the jasmine comes through properly, and that is how I would order it. At full sugar the grape flattens into one note and the tea stops registering at all.
The large runs $10.99 at 290 calories. That is $1.50 more money for 80 extra calories, which makes the large better value per ounce. I would still take the regular. 290 calories puts the large cup above most of the milk teas on this board, and you are unlikely to notice the extra volume as much as you notice the number.
Order this if milk tea feels too heavy to you but you still want something with body. It also works well in hot weather, since there is no dairy in the base at all. The one group I would steer away from it is anyone expecting a dessert. No foam cap, no pearls, no cream anywhere in the standard build, and it tastes noticeably drier than the cloud drinks sitting beside it.
For pairing, Cloud Crisp Grape is the same grape tea with a salted cheese cloud on top, which turns the tart finish creamy and adds a little over a hundred calories. In the other direction, Kale Boost Tea keeps the green apple and jasmine profile but drops to 180 calories. That is the one I reach for when the grape version starts feeling too sweet.

Best toppings for the Crisp Grape Boom
The Crisp Grape Boom starts at $9.49 and every topping is charged on top of that. Matcha Jelly is the cheapest of the three at $0.98, and all three together would take the Crisp Grape Boom to $14.93 and 460 calories.
| Topping | Add on | Cal | Cup total | Why it works here |
|---|---|---|---|---|
| Coconut Milk Jelly | +$1.58 | +70 | $11.07 280 cal | Soft cubes that suit a fruit tea far better than chewy tapioca, and the coconut reads as sweetness without adding sugar to the base. |
| Matcha Jelly | +$0.98 | +60 | $10.47 270 cal | The cheapest way to add chew at $9.49 plus a little under a dollar, and the green tea flavour matches the jasmine underneath. |
| Cheese Cloud | +$2.88 | +120 | $12.37 330 cal | Adds the salted foam cap, which rebuilds the drink into Cloud Crisp Grape for slightly less than ordering that cup outright. |
These three suit the Crisp Grape Boom in particular, and the remaining 4 options sit in the full toppings table with what each one does to a mid board cup.
How to make a Crisp Grape Boom at home
You pay $9.49 for this in store, so a home batch covers itself in the first round. The part I would tell you to get right is the pulp. A blender turns the grapes to juice and you lose everything that makes this drink interesting, so muddle them by hand instead.
Ingredients
Jasmine tea base
Grape layer
To serve
Method
All steps done. Your Crisp Grape Boom is ready to pour.
Tips that actually change the result
- Four jasmine tea bags stand in for the loose leaf if that is what you have. Pull them at 3 minutes the same way.
- Cold grapes matter. Room temperature fruit turns the whole drink lukewarm before you finish building it.
- Taste the tea on its own before you add anything. A bitter base cannot be fixed later with sugar.
- Halve the syrup on the first attempt. The shop version at full sugar is sweeter than most people expect once they make it themselves.
Ways to change it
- Whip 60g cream cheese with 40ml cream and a pinch of salt, then float it on top to build the cloud version.
- Swap half the grapes for green apple to move the drink toward the Kale Boost profile.
- Use a longjing green tea base instead of jasmine for a rounder, more roasted finish.
How the Crisp Grape Boom compares
All three sit on the same jasmine green tea base. What separates them for me is the fruit load, the cheese cloud, and roughly forty calories.

Crisp Grape Boom questions
How much is the HEYTEA Crisp Grape Boom?
The regular cup is $9.49 and the large is $10.99 at US locations. Prices move a little between cities, and mall stores tend to sit at the top of the range. Toppings are charged separately, starting at $0.98.
How many calories are in a Crisp Grape Boom?
The regular cup lists 210 calories and the large lists 290. Those figures are for the standard build at default sweetness. A lower sugar level reduces the count, and brown sugar bobo puts another 100 calories on top.
Does the Crisp Grape Boom contain dairy?
The standard build has no dairy in it. The base is jasmine green tea with crushed grapes and ice. A cheese cloud topping does add dairy, and so does a switch to Cloud Crisp Grape, which comes with the foam cap as standard.
Does it have caffeine?
Yes. The drink is built on jasmine green tea, so it carries the caffeine that comes with a brewed green tea base. HEYTEA does not publish a milligram figure per cup in the United States, so we do not quote one here.
Is the large cup worth the extra money?
On price per ounce it is the better buy, since $1.50 adds a meaningful amount of drink. On calories it is a real jump to 290, which is higher than most milk teas on the board. Order the regular if the calorie number matters to you.
