Frequently Asked Questions

Sourdough Supplies was born out of a passion for baking, cultivated during the pandemic when we dedicated time to creating delicious baked goods for our families. As our love for baking deepened, we realized a gap in the local market for high-quality baking tools and ingredients that met our standards.

Driven by this discovery, we set out on a mission: to empower home bakers, bakeries, and restaurants with premium baking equipment and specialty bakeware, enabling them to create better food, drinks, and moments.

Today, we proudly provide an extensive range of products—from Weck Jars to premium flours—helping bakers across Singapore elevate their craft and enjoy the art of baking to its fullest.

We do not have a physical store location, but we are based in Singapore and have two warehouses located at:

9 Loyang Way, #04-01 Krislite Building, Singapore 508722
