"One of Gloucester Road's only in-house roasters, which already puts it ahead of most of the strip. The Vietnamese Robusta on the menu is the tell: someone here makes sourcing decisions on purpose."

Triple Co is a working roastery, not a café that happens to sell beans. Come in for a bag of Jumpstart and leave with a subscription you'll be renewing two years later.
Lost Horizon roasts its own beans on-site in Stokes Croft. Order the pour-over.
Wogan roasts on-site and serves those beans across the brew bar. Order from the tasting notes; take a bag home from whatever's fresh off the roaster.
