About the Mango Grapefruit Boom
A regular Mango Grapefruit Boom is $9.99 and 210 calories, and the large takes you to $11.49 and 280. Mango pulp and grapefruit segments go into a jasmine green tea base together, and the two fruits are doing opposite jobs. That tension is the drink, and it is why reactions split so cleanly.
Grapefruit carries a bitterness in the pith and membrane that most fruit drinks work hard to remove. This one leaves it in. Against mango, about as straightforwardly sweet as fruit gets, the result swings between the two on every sip. If you like an Aperol spritz or marmalade you will recognise the appeal immediately. If you find grapefruit unpleasant you will find this unpleasant, and no amount of sugar adjustment fixes that.
The jasmine base is almost inaudible here, which is unusual for the Boom range. With two loud fruits in the cup there is no room for a floral note, and the tea works mainly as liquid and a little tannin. That is not a criticism, it is simply how this is built. If you came to taste the tea you have picked the wrong cup, and Green Grape Boom is the one that does that job.
The size step deserves a closer look than usual. The large runs $1.50 more for 70 extra calories, the largest price step among the two size drinks here. Grapefruit also gets more bitter as ice melts, because dilution hits the mango faster than the citrus. Drink a large slowly and it finishes sharper than it started.
Order this if you like bitterness in a drink, if you find most bubble tea too sweet, or if you want something that changes as you drink it. Skip it if you want a straightforward fruit tea. Cloud Mango is the sweet mango drink, Coconut Mango Boom is the creamy one, and Grapefruit Boom is for anyone who wants the citrus with no mango softening it.
A grapefruit pulp topping at {PRICE:grapefruit-pulp} pushes this further toward the bitter end, which is the direction its regulars take it. A coconut milk jelly does the opposite, and that is the better call if you find it slightly too much.

Best toppings for the Mango Grapefruit Boom
The Mango Grapefruit Boom starts at $9.99 and every topping is charged on top of that. Sago is the cheapest of the three at $0.98, and all three together would take the Mango Grapefruit Boom to $14.13 and 400 calories.
| Topping | Add on | Cal | Cup total | Why it works here |
|---|---|---|---|---|
| Coconut Milk Jelly | +$1.58 | +70 | $11.57 280 cal | Softens the citrus edge without adding sugar, and it is the standard fix for anyone who finds the drink slightly too sharp. |
| Grapefruit Pulp | +$1.58 | +40 | $11.57 250 cal | Pushes it further in the direction it already goes, at 40 calories. The pick for people who order this drink on purpose. |
| Sago | +$0.98 | +80 | $10.97 290 cal | Neutral chew that gives the cup some weight at the bottom without interfering with either fruit. |
These three suit the Mango Grapefruit 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 Mango Grapefruit Boom at home
Your home version lives or dies on how you handle the grapefruit. Cut properly, away from the membrane, it gives you a clean bitterness. Juiced whole, it gives you a harsh one that dominates everything else in the cup. In store this is $9.99.

All steps done. Your Mango Grapefruit Boom is ready to pour.
Tips that actually change the result
- Pink grapefruit rather than white. White grapefruit is considerably more bitter and the balance tips too far.
- Salt the mango, not the grapefruit. Salt on citrus emphasises the bitterness rather than softening it.
- Build it and drink it. This is not a drink to make an hour ahead, since the grapefruit sharpens as it sits.
Ways to change it
- Leave the mango out entirely for a Grapefruit Boom style cup.
- Swap the grapefruit for pomelo, which is sweeter and much less bitter.
- Add a spoon of honey to the mango for a rounder, less acidic finish.
How the Mango Grapefruit Boom compares
Four mango and citrus builds. This is the only one that keeps real bitterness in the cup, and that is the single thing I would decide on.

Mango Grapefruit Boom questions
How much is the HEYTEA Mango Grapefruit Boom?
A regular runs $9.99 and the large goes to $11.49. That $1.50 step is the largest size upgrade cost on the US board.
How many calories are in a Mango Grapefruit Boom?
Count 210 calories in the regular and 280 in the large. The mango accounts for most of the sugar, so a reduced sweetness level pushes the drink further toward the bitter side.
Is the Mango Grapefruit Boom bitter?
Yes, deliberately. Real grapefruit segments go in and the bitterness is part of the design rather than a fault. Anyone who dislikes grapefruit should order Cloud Mango or Coconut Mango Boom instead.
Does it contain dairy?
No. The standard build is jasmine green tea with mango and grapefruit, so there is no dairy in it. A cheese cloud topping would change that.
Which is more bitter, this or the Grapefruit Boom?
Grapefruit Boom at $9.49 is the sharper of the two, since there is no mango in it to balance the citrus. This drink is the gentler introduction to the grapefruit side of the menu.
