SAN FRANCISCO

WITH its brass-trimmed halogen heating elements, glass globes and bamboo paddles, the new contraption that is to begin making coffee this week at the Blue Bottle Café here looks like a machine from a Jules Verne novel, a 19th-century vision of the future.

Called a siphon bar, it was imported from Japan at a total cost of more than $20,000. The cafe has the only halogen-powered model in the United States, and getting it here required years of elliptical discussions with its importer, Jay Egami of the Ueshima Coffee Company.

“If you just want equipment you’re not ready,” Mr. Egami said in an interview. But, he added, James Freeman, the owner of the cafe, is different: “He’s invested time. He’s invested interest. He is ready.”

Professionals have long been willing to pay prices in the five figures for the perfect espresso machine, but the siphon bar does not make espresso. It makes brewed coffee, as does another high-end coffee maker, the $11,000 Clover, which makes one cup at a time. Together, they signal the resurgence of brewing among the most obsessive coffee enthusiasts.
