"Hammerling Wines is among a handful of natural winemakers occupying a stretch of Fifth Street near Gilman in North Berkeley. Hammerling spearheaded the return of the popular First Friday Gilman Wine Block Party, where they and nearby wineries Donkey & Goat, Broc Cellars, and others bring pop-ups to the area and visitors are encouraged to sample different wines on the first Friday of every month. Otherwise, Hammerling is open on the weekends or by appointment." - Dianne de Guzman
