Roasters worth the detour.

The roaster most Alishan estates name first; buys small lots by the sack.

A small roastery across the river with a serious Taiwanese-bean programme.

One of the old guard, still roasting darker than most and doing it well.

A converted garage with a 5-kilo drum and no shop front; you buy at the door on Saturdays.

A two-person operation with a narrow, rotating list and no house blend.

Competition-proven lots, roasted in small batches and sold mostly through the café.
