BPA-Free Materials + 304 lids: Built around clear glass jars, BPA-free silicone accessories, and 304 stainless steel lids for daily sourdough care. The metal lids help avoid rusty-lid worries in fridge storage; wipe them dry after washing to keep the finish looking clean.

Two-Jar Feeding System: Sourdough feeding is easier when one jar can stay clean and ready. Rotate between two 34 oz jars as you discard, feed, swap, and wash, helping keep your starter routine cleaner and more consistent.

Extra-Wide Mouth design: The 3.3 inches mouth opening gives you more room for spatula stirring, scraping, pouring, and hand cleaning. The straight glass body helps reduce dough trapped around hard-to-clean areas.

Ready-to-Start Accessory Set: Includes 2 glass jars, 304 stainless steel lids, silicone spatula, feeding band, thermometer sticker, breathable cloth cover, and instructions. Designed for maintaining starter; live starter culture, flour, and baking ingredients are not included.

Clear 1L glass for daily baking: The 34 oz / 1L soda-lime glass jar gives starter room to rise while staying easy to observe on the counter or in the fridge. Great for tracking daily feeding, maintaining white and whole wheat starters, and preparing for bread baking days.
