Coffee Stain
Owner-operated espresso bar · 1 location · Brooklyn: Williamsburg
A Williamsburg espresso bar that opened in July 2026 with no website and a three-word Instagram bio. Its two owners are the named contacts on their own state filings, and no investor turns up anywhere. This early, that is most of what is known.
The Big Picture
Coffee Stain is a single Williamsburg café, opened in July 2026 by two named owners, with no investor, parent company or franchising on record. It is too new to have much of a labor or environmental record, though its coffee comes from a named Long Island roaster. It answers to its two owners and nobody else.
