Another installment in SF’s series of “espresso bars in strange places,” this one — open since 2009 — is located in a sort of gift shop. It’s a very small space identified by its bright green exterior, and there are a couple of small chairs for sidewalk seating. Inside there are mirrors, planters, birdcages, bath oils, glassware, candle holders, and other odd home gifts — with two small tables in front and an espresso bar in back.

Here they use a two-group La Marzocco Linea to pull shots of Ritual Roasters coffee. They were pulling shots of Ritual’s anniversary Five Candles blend when we visited — recently replacing months of their Evil Twin seasonal blend. The barista identified their Evil Twin blend as being much more forgiving than the two-second extraction range that the Five Candles could tolerate. And they do time their shots here: she sank (as in sink shot) a 17-second shot before letting a 24-second shot pass.

The espresso had a mottled medium and darker brown crema, poured rather short in white Nuova Point cups. It was bright, fruity (sour green apple fruity), and a touch thin – likely reflecting the new espresso blend more than anything else. Regarding the fruity descriptor, Ritual even uses the phrase “golden apple” – though it was more green apple. And that kind of sourness just doesn’t have a place in the flavor profile of espresso shots we like very much. Perhaps others will find it interesting.

Hollow is generally known for making some of the best espresso in the Inner Sunset, but the Five Candles blend didn’t let them shine. This is a case where a coffee bean roaster/supplier changes up their blends with the growing seasons and sometimes gets too clever — producing underwhelming results for the retail café.

Coincidentally, this afternoon we were looking for a decent espresso in Yountville following the fantastic release party of a winemaker friend of ours. Walking up to the nearby Yountville Coffee Caboose, we asked what Ritual blend they used for their espresso pulls. When they answered “Five Candles,” we instead walked over to Bardessono.

The woman working the Caboose’s register may have been surprised at our reaction, but the Five Candles blend really is that disappointing. It carries many of the signature problems we’ve created when we’ve overweighted more lightly roasted Central American beans in our own home-roasted espresso blends.
