Why we opened this bar
Thai flavour deserves to travel further
Every morning Thailand drinks millions of cups of coffee, yet few people know that some remarkable beans grow on our own mountains — ripened through cold winds, mountain mist and farmers who tend every tree.
Phirom Coffee Lab exists to take Thai ingredients further — into specialty-quality drinks — and to tell their story with every cup.

Peaberry in every cup
The single round bean found in only about 3–5% of coffee cherries, hand-sorted from farms above 1,200 m.
Know where it's from
Thai beans from Chiang Rai, Chiang Mai, Nan and Lampang — every bag names its farm, altitude and process.
Lab-style menu
Signature drinks developed in-house, found only here.
Easy to love, easy on the wallet
Specialty coffee for every day, from 65 baht a cup.
More than a coffee bar
A coffee bar inside a building that grows and extracts plants
Phirom Coffee Lab sits inside the Advanced Plant Factory with Artificial Lighting building, in the grounds of KAPI at Kasetsart University. This four-storey building holds everything from plant-growing rooms and a formulation lab to the extract and herbal-products facilities of our partner K‑API (K‑API Co., Ltd.). The people working around us study Thai plants every day.
