GWTQMJI Sourdough Starter Jar Kit 2-Pack — 50oz & 34oz Wide-Mouth Borosilicate Glass with Lids & Tools

Whether you’re building your first starter or keeping multiple cultures active, this complete kit supplies the core containers and accessories for reliable daily feedings and batch fermentation. The jars are made of heat-resistant borosilicate glass so they tolerate temperature swings from fridge to counter. Two lid types let you choose between slow, airtight chilling and a breathable cover for faster fermentation, while included trackers and a thermometer simplify routine maintenance.

How do these jars make feeding and stirring easier?

The extra-wide mouths create generous openings for stirring, scraping and transferring starter without spills or hard-to-clean corners. Wide rims accommodate the silicone scraper and spoon included in the kit, and the graduated marks on the glass help you measure volume during refreshments.

• Large 50oz and smaller 34oz mouths for easy access and pouring
• Graduated volume marks etched into the glass for precise feeding
• Silicone scraper and measuring spoon fit comfortably through the opening
• Borosilicate glass resists staining and odor retention for clean handling

Can I control fermentation speed and temperature?

You can switch between airtight slow fermentation using the bamboo lids and quicker, oxygen-friendly fermentation with the breathable cloth covers. The kit’s stick-on thermometer and elastic date band let you track ambient temperature and feeding times so you can keep your starter on a consistent schedule.

• Bamboo lids provide a seal for chilled or slow fermentations
• Breathable cloth covers allow gases to escape during active fermentation
• Included jar thermometer helps monitor temperature for predictable activity
• Elastic date-marking band records last feeding at a glance

What accessories are included and how do they help daily baking?

This all-in-one sourdough set comes with tools chosen to simplify starter maintenance and small-batch prepping. You’ll receive complementary utensils and stabilizing accessories that reduce mess and help you move from feeding to baking more efficiently.

• Two bamboo lids and two cloth covers for flexible fermentation options
• Two thermometers and two date bands to monitor separate starters
• Two silicone anti-slip mats to keep jars steady during mixing
• Silicone scraper, baking spoon and graduated measuring cup for accurate handling

How should I care for these jars and tools?

The borosilicate glass and most accessories are dishwasher-safe, though hand washing is recommended for the temperature sticker to preserve its accuracy. Keeping the bamboo lids dry and wiping silicone parts clean will extend the kit’s lifespan and maintain hygienic starter storage.

• Dishwasher safe for glass — hand wash the thermometer sticker area
• Wipe bamboo lids dry to prevent moisture damage
• Remove silicone pads for thorough cleaning under the jar base
• Store cloth covers dry between uses to avoid mildew
