Frequently asked questions

Lid loose or clipped on?
Loose (lid resting) while it's active; ring and clips only for sealed fridge storage or travel.
Why not just seal it airtight?
An active starter produces CO2, and sealing it can build pressure, so let it breathe.
What size jar do I need?
Around 580 to 850ml suits most home bakers, with room to double without climbing out.
Which lid and seal fit my jar?
Match the opening size: RR60 = 60mm, RR80 = 80mm, RR100 = 100mm. The jar's name tells you which.
Dishwasher safe?
The glass jar and lid, yes. The rubber rings last longer hand-washed.

Lids fit comfortably but loose enough to release gases.

I make sourdough starter. My lid slipped out of my hand and smashed on my kitchen tiles. (Totally my fault as I have a hand tremor). The jars and lids are sturdy and well made. I didn’t want to go without my sourdough bread so ordered x3 spare lids for each of my glass jars that I have.

Hi Vicky, thank you for your purchases. I hope you don't need the spares but glad you have them just in case. Happy baking Stacey @ Sourdough Supply

Love the jars I have bought from you and thankfully the second purchase was delivered without any issues (thanks for your help last time). Great company and very good prices.

Hi Laura, sorry for the initial mix-up we are pleased you are happy with your purchases. Thank you for your review. Happy baking!
