Costco's Kirkland Olive‑Rosemary Bread Sparks Sour‑dough Labeling Debate
Costco introduced its Kirkland Signature olive and rosemary sourdough bread, making it available in warehouses across the United States. The product quickly became a flashpoint for consumers and sourdough purists who argue that authentic sourdough must rely solely on a live starter culture, without commercial yeast or additives. The Real Bread Campaign, whose coordinator Chris Young coined the term “sourfaux” in 2015, says the loaf contains commercial yeast, yeast extract and other ingredients that disqualify it from true sourdough status. Online discussion on Instagram, Reddit and other platforms reflects a split opinion: many shoppers praise the taste, while others urge people to support local micro‑bakeries and avoid what they view as misleading labeling. The controversy highlights the tension between large‑scale retail convenience and traditional baking standards.
The debate has drawn attention from food‑industry observers about labeling practices and consumer transparency in the bakery segment.
