Flywheel owner Aquiles Guerrero has coffee in his blood. He was born on a coffee farm in Nicaragua and grew up picking coffee. His family owned Martha and Bros. coffee shop, and he became a barista at age 12 and a roaster at age 18. (He even met his wife, Marissa, at Capuchino High School in San Bruno.) Guerrero’s spacious Haight cafe is purposefully designed to avoid a corporate feel, outfitted with reclaimed wood and minimalist pendant lighting. The coffee is sourced from Ethiopia, Costa Rica, and Kenya and overseen by Flywheel’s master roaster Stephen Beebout.
