Since 1909. Restaurant size. Tangy, flavorful taste. Great sandwiches start with great bread! Soft hearty slices - big hearty taste. Samuel Rosen always love bread - it was his passion. He was awarded his Master Baker's Certificate at the age of 12 and moved from Europe to America that same year, 1898. By 1902, he owned his very own bakery in New York City and by 1909 moved to larger facilities in Chicago. Samuel Rosen's pride in the taste and quality of his breads has been maintained now through three generations of Rosen's family, becoming something of a legend in Chicago and throughout the United States. Enjoy the tangy, robust flavor for this San Francisco Style Sourdough. Perfect for grilled sandwiches or any special sandwich. A truly delicious way to make your sandwich special. - Sam Rosen.
