SAN JOSE, CALIF. — Custom beverage startup Frazy has developed a line of shelf-stable boba tea.

The direct-to-door product builds off the company’s Frazy Bottles coffee format and comes with a 2.5-oz aluminum bottle of tea concentrate, a vacuum-sealed packet of boba tapioca pearls and milk powder. After softening the tapioca pearls in the microwave for three seconds, the ingredients combine with hot or cold water to create an 8-oz beverage.

Consumers can personalize their drinks on Frazy’s website by selecting their preferred tea variety, sweetness level and type of milk, such as whole, oat, soy and non-fat milk or non-dairy creamer. Flavors at launch include brown sugar milk tea, milk black tea, almond black milk tea, peach black tea, mango black tea and honey milk black tea.

“Our new boba teas mark the next step in the evolution of Frazy Bottles,” said Balaji Krishnan, founder and chief executive officer of Frazy. “Our wide variety of options enables people to try different customized boba teas they wouldn’t have a chance to order otherwise, and also allows consumers who live in markets that don’t have boba to enjoy their favorite boba tea at home, work or on the go.”

 The boba is now available, in packs of 6 or 12, exclusively through the company’s website. Frazy’s latest product line looks to capitalize on the growing boba tea market among Gen Z consumers, which is estimated to reach $4.4 billion in revenue by 2027, according to Allie Market Research.

The company also has added 12 new flavors of its Frazy Bottles coffee concentrate, including red velvet latte, tiramisu latte, hazelnut mocha and holiday varieties like pumpkin pie spice latte and gingerbread latte.
