When he and his wife Gabriele immigrated to Kaslo, B.C., from a small Bavarian town in the summer of 1979, Silvio Lettrari craved the sourdough bread he grew up eating. He began baking and selling his own loaves as a summer project in 1991. Locals raved and demand grew, so the couple launched Kaslo Sourdough in 1993 and marketed their bread across the West Kootenays.
