The Sourhouse Starter Jars are designed to be the easiest-to-clean sourdough starter jars in the world.

You see, there are no threads where your starter can collect and gunk up.

The soft, silicone lid hugs the outside of the jar to keep contaminates out of our jar. It stays in place with just enough friction to be secure while still letting gases out. Dry starter flakes off the lid with a squeeze.

The jars have a flat bottom, so it gets great contact with Goldie's warming base for efficient warmth transfer. 

They are made of very clear, borosilicate glass so it is easy to see any bits of dry flour that need to get mixed up into your starter. And of course, this starter jar has straight sides so it is easy to mix, clean and track the rise of your starter. 

• On the sides of each PINT size jar are dots in 50ml and 100ml increments for judging when your starter has doubled (or tripled).
• Our QUART size jar has 100ml and 200ml dots for those of you who like to keep larger starters or to build a levain in advance of a bake.

Both the PINT and QUART jars leave enough clearance inside Goldie to use a Sourhouse Cooling Puck.

For size reference, all of the pictures of Goldie this site have a PINT jar inside.

Each jar comes with a gold silicone marking band too.
