MANILA -- Serenitea is celebrating its 15th anniversary by releasing a pair of holiday drinks in collaboration with Pan De Manila.

The milk tea chain took the bakery's yema and ube to create two new beverages. Yema Mais Con Yelo mixes green tea with sweet corn, syrup, and ice, with a topping of yema and cheese shavings.

Ube Pandan Green Tea, on the other hand, blends ube-halaya with green tea, pandan, and coconut strips.

The two drinks are now available in all Serenitea branches nationwide, and can also be ordered via third-party delivery apps such as GrabFood and Foodpanda.

Meanwhile, Serenitea is also holding the Jumbo Cup promo from December 14 to 16, allowing customers who order select large drinks to get a free 1-liter jumbo upsize for free.

Participating drinks for this year include Pearl Milk Tea, Okinawa Milk tea, Hokkaido Milk Tea, Wintermelon Milk Tea, Summer Breeze, Winter Frost, Fruitea Green Apple, Fruitea Lychee, Fruitea Cranberry, Brown Sugar Regular Fresh Milk, Taro Lover and Creme Brulee Milk Tea.
