Yin Sourdough is our partner supplier for their healthy breads. Their breads are naturally fermented and made from unbleached GMO flour and no added commercial yeast. No addictive, improver, softener, preservatives or any chemical in the process of baking. You can always visit their outlets not only for sourdough bread, but also their roasted coffee and homemade jam. We are lucky to be their chosen one to distribute their products.
