Rubies + Diamonds Pairs the Classic With Cutting Edge in Los Angeles
The company is very guarded about its green coffee sources given the intensely competitive market they call home. Much of it they say is directly sourced from growers, although — in another old-vs-new move, harkening back to an out-of-favor bean making a comeback only in the most forward-thinking circles — they do offer a single-origin Robusta from India that they procure by way of the Portland-based Sustainable Harvest import company. Served either as batch or BKON brew, R&D’s straight Robusta takes the top rating in the shop’s trademarked CAF — Caffeine Amplitude Formula — rating system, by which patrons can choose drinks based on the stimulant boost it provides. Decaf is CAF0; the Robusta is CAF4, and everything else falls somewhere in between.
