70-year-old grandmother's viral Bangkok roastery, from two stools to four locations.

Ploenpit Rianmek opened with two stools on Mahaphruttharam Road in February 2019 at age 70. The grandmother barista with three decades of experience went viral on Thai social media within weeks. Her son handles most brewing while Pa Pim works the ROK manual espresso makers, rotating unpredictably between locations.

Thai beans span Doi Saket, Doi Sam Muen, Mae Jun Tai, and Pangkhon from Chiang Mai and Chiang Rai. Imports reach from Panama Gesha Ninety Plus and Yemen Mokha Mattari to Honduras whisky barrel-aged and Kenya Kirinyaga Gesha. Six house blends include Hidden Whisky pairing Chiang Mai Mae Tang with Honduras Finca Moka, and Eclipse Melon adding Colombian melon barrel-aged.

At this shop

The shop fills the ground floor of a two-storey shophouse at Pratu Phi, with wood-framed glass doors and planters along the pavement. Inside, a steel-fronted bar runs across a high room of bare plaster walls and exposed beams, and red-and-white floor tiles lead to the glazed front, where seats face the street.
