Tapioca pearls slow-simmered with brown sugar until they sit in a thick, dark caramel, then smeared in tiger-stripe streaks up the inside of a clear cup and topped with cold fresh milk — no tea. The drink is meant to be seen before it is drunk: amber streaks bleeding down through white milk. It rode a viral wave from Taichung in the late 2010s.
Brown-sugar boba is a modern Taichung drink that exploded in the late 2010s. Tiger Sugar opened its first stall on Taichung's Yizhong Street in November 2017, selling little but brown-sugar drinks, and its 'tiger-stripe' cup became a craze that spread to Hong Kong and beyond within a year. In July 2018 the brand admitted its syrup was not the hand-stirred brown sugar its marketing claimed but a concentrate containing caramel colouring — a reminder that the wave was built as much on image as on craft. Countless shops have since sold their own versions.
First the eye: dark syrup clinging in streaks to the glass, milk going from white to tea-brown as you stir. Then the mouth — cold fresh milk, rich and barely sweet, suddenly meeting the warm chewy pearls drenched in molasses-deep brown sugar. The contrast of cold milk and warm caramel pearls is the whole point; the bottom sip is the sweetest, almost a dessert.
The look and taste come from caramelisation. Simmered long and slow, the brown sugar's sucrose breaks down and browns into hundreds of aroma compounds — the smoky, bittersweet 'burnt-sugar' note and dark colour — while reducing to a syrup thick enough to cling to glass instead of sliding off, which is what holds the tiger stripes. The pearls, boiled then steeped in this syrup, drink it in and stay glossy. Served warm against cold milk, the two never fully mix, so each stir paints a new pattern.
Variations
Most often served with fresh milk, but also with milk tea, fresh-milk plus a cheese-foam cap, or over ice cream. Some shops use the larger boba pearls; reduced-sugar is harder here since the sugar is the drink. Hot versions exist for winter. Quality hinges on whether the brown sugar is genuinely cooked down or faked with syrup and colouring.

- 120 min
Boil the tapioca pearls in plenty of water until floating and translucent through, then drain.
- 212 min
Return the drained pearls to a pan with brown sugar and a little water and simmer low, stirring, until a thick dark caramel coats them.
Watch outSimmer the sugar and pearls until the syrup goes thick and dark enough to cling to the glass — thin syrup slides down and won't hold the tiger stripes.
- 33 min
Spoon the syruped pearls and some of the caramel into a clear glass, swirling streaks up the sides.
- 43 min
Pour cold fresh milk slowly over the pearls so it layers above the dark syrup.
Watch outPour the cold milk slowly over the warm syrup so the two layer instead of mixing — that's what paints the stripes down the glass.

Serve at once with a fat straw, to be stirred just before drinking.
