This specialty shop uses the Blue Bottle Kyoto-style cold-brewing system, a fancy-looking and somewhat costly setup comprised of tall, fragile glass drip towers, traditionally called an Oji machine in Japan. Drip by drip — 48 drips per minute, to be exact — the Oji produces a six-cup batch after around seven hours. If this sounds highly specialized, that’s because it is. Small batches with extremely high caffeine content means the drink is typically prepared by pouring four ounces over ice for an exceptionally deep, smoky, and light-bodied coffee experience. A regular-sized cup (16 ounces) costs $3.82; a large (20 ounces), $4.35.Read the full story on Harold's Coffee in West Palm Beach and other iced coffees in South Florida.
