The Yuzu Brown Sugar Oolong Kit is a two-piece Taiwanese drink set: four bottles of Real Leaf cold-brew Jin Xuan oolong — the milky, floral cultivar Taiwan is known for, with no added sugar — and a 308 g box of YOU YI CUN's yuzu peel brown sugar cubes. You sweeten to taste, and the sweetener itself carries Madou yuzu peel oil, so the tea picks up citrus aroma rather than just sugar.
What's in this bundle?
-
Real Leaf Cold Brew Jin Xuan Oolong Tea — 450 ml × 4 bottles (Taiwan). Cold-brewed Jin Xuan oolong, no added sugar. Smooth and floral with the cultivar's signature creamy note.

2 items. Ice, milk and tapioca pearls not included.
How do you make iced yuzu brown sugar oolong?
The one rule: dissolve the cube in hot water first. It will not dissolve in cold tea.
- Drop one yuzu brown sugar cube into 30–40 ml of hot water and stir until completely dissolved. This is your syrup.
- Optional: streak the syrup down the inside of a tall glass for the brown-sugar-boba look.
- Fill the glass with ice.
- Top with about 250 ml of chilled Jin Xuan oolong — roughly half a bottle.
- Stir from the bottom up. Add a second cube if you want it dessert-sweet.
Hot version: dissolve one cube in 250–300 ml hot water and top with warmed oolong.
Milk tea version: add 60 ml of oat or whole milk and cooked tapioca pearls for a yuzu brown sugar milk tea.
Frequently asked questions
Is this Japanese yuzu?
Not quite. The sugar cubes are infused with peel oil from Madou pomelo (文旦柚) grown in Tainan, Taiwan — a citrus in the same family as Japanese yuzu (Citrus junos) and used the same way. In a drink, Taiwanese yuzu peel reads more floral and rounded, closer to grapefruit zest, with less of Japanese yuzu's sharp acidity.
Is Jin Xuan a black tea?
No. Jin Xuan (金萱, Taiwan Tea No. 12) is a lightly oxidised oolong, not a black tea. It is known for a naturally creamy, milky aroma even with no dairy added.
How sweet is one cube?
That is deliberately up to you — the base tea is unsweetened, which is the whole point of the pairing. Start with one cube per glass and add a second if you want it closer to a dessert drink.
What else can I use the brown sugar cubes for?
Syrup for tangyuan or douhua, sweetening coffee, baking, pancakes, or dissolved into hot water on its own as a Taiwanese-style hot brown sugar drink.
