Costco Bakery Blueberry Sourdough Bread is a freshly baked artisan-style loaf made with a sourdough base and studded with blueberries throughout. The sourdough fermentation process gives the bread a characteristic mild tanginess, while the blueberries add natural sweetness and bursts of fruit flavor in every slice.

This bakery bread is well-suited for breakfast toast, a side with brunch spreads, or enjoyed on its own. The sourdough process also contributes to a chewy crumb and a hearty crust, typical of Costco's in-store bakery offerings.
