Costco Tropical Fields Boba Milk Tea Mochi Review

Have you ever tried mochi? Mochi is kind of hard to describe if you haven’t had it before – it’s a rice cake with a very unique texture. Wikipedia does a better idea of describing it than I probably would! Anyway, I’m reviewing the Costco Boba Milk Tea Mochi today. I’ve had mochi before, but I’ve never tried boba mochi. I really like boba in beverage form, but I haven’t loved mochi when I’ve tried it before. I’m curious if these Boba Milk Tea Mochi are good!

Similar products from Costco are the Costco Boba Bam Instant Boba Pack, Costco Brown Sugar Boba Bars and the Costco Formosa Mochi Dessert Assortment.

Location in Store

These are located in the snack section at Costco, near the granola bars, protein bars and candy. The item number is 1571731.

So fun to try these Tropical Fields Boba Milk Tea Mochi from Costco!


The Costco Boba Milk Tea Mochi are pillowy soft! The texture is extremely squishy, chewy and almost gelatinous. The flavor of the boba mochi is very sweet, borderline too sweet. There’s a slight hint of brown sugar flavor coming from the center but not much other flavor other than sweetness and I didn’t get any tapioca pearl flavor.

Ready to enjoy!

The boba milk tea mochi are very fresh tasting from being individually packaged and the outside is slightly powdery. When enjoyed frozen, they are much firmer but not hard and still chewy. The texture of them frozen reminds me of a tapioca pearl from a bubble tea. I actually prefer them frozen.

So squishy and chewy!

The package shows these having a tapioca pearl on the inside and milk tea flavor surrounding the tapioca pearl, they’re too soft and squishy to notice a discernable tapioca pearl.

The 900 gram bag of 60 individually package Tropical Fields Boba Milk Tea Mochi costs $9.99 Canadian at Costco which isn’t really unreasonable for a unique food product like this!

I love the individual packaging! Makes it easy to pop a few in your purse!


Each Costco boba milk tea mochi is individually wrapped which keeps them very fresh tasting! The bag recommends storing them in the freezer or keeping them in a cool, dry place.

They definitely are soft, chewy and like a cloud!

The best before date is a year and two months from the date we purchased them. I think these make a good snack or dessert. I probably can’t eat more than one or two because they’re so sweet.

Best to store the mochi in a cool, dry place! You can even try freezing them for a cool treat.



Two pieces of Costco Boba Milk Tea Mochi is 110 calories, two grams of fat, 22 grams of carbohydrates, zero grams of fibre, six grams of sugar, zero grams of protein and 10 mg of sodium. I’m surprised there are only six grams of sugar because I find these taste so sweet!

Costco Tropical Fields Boba Milk Tea Mochi nutrition facts.
Surprising to see only six grams of sugar.


This is a long list of ingredients with a lot of things on it that I don’t recognize or know what they are. Such as trehalose? Isomalto-oligosaccharides? The mochi contains milk and soy and may contain egg, wheat, gluten, sesame, peanuts and tree nuts. I can tell you that you get zero nutrition from the Costco Tropical Fields Boba Milk Tea Mochi, these are definitely a treat and something I personally would try not to eat a ton of.

Give it a try!

I’m not a big mochi person, to be honest, but these aren’t bad. One or two are pretty tasty, but after that, I find them too sweet. If you’re someone who wouldn’t like the gelatinous, squishy texture, you’ll probably want to pass on these as that’s probably the main thing you’ll notice when you’re eating them!

  1. Tropical Fields boba milk tea mochi is horrible. Dry flakey powdery and tastes bad,
    I bought two bags and they are going back!

  2. They are horrible unlike the first batch costco sold. They are hard powdery and flakey. I bought two packages from another costco store after the one I normally go to ran out. They’re going back!

  3. I love boba tea mochi but there is none in the warehouse , one bad thing about Costco is , bringing certain food or some other items that we like but next time is not there. There was a shrimp with pasta with the saucer , great dinner , I loved it, I have been looking for a year , never came back . So are you bringing boba tea mochi and shrimp ? I hope so

    • I agree like the Chimichangas they are the best but no where do I find them. This was staple item for many ppls dinners. Why dear God why must you get your customers worked up when you get something good in, then you turn around & discontinue the product? Yes. I get it you try too keep customers guessing like wondering whats new this week at costco? Just to luer them back in hoping they see other stuff to buy! Well not all ppl work that way, its a total let down. & discouraging & this makes people stop going to Costco. having a card doesnt stop them from going elsewhere. This im sure affects revinue & business is affected.. just saying. PLEASE RETURN THE CHIMICHANGA’S PLEASE 🙏 🙏 🙏 🙏🙏 🙏 🙏 🙏
