Organic Sourdough Starter Kit


What is sourdough bread?

Sourdough bread is well known for its tangy flavor, crusty crusts, and chewy texture. It is far healthier than store-bought bread as the process of fermentation breaks down the gluten, making it far easier for our bodies to digest. 

What is a sourdough starter?

Sourdough is a naturally leavened or fermented bread that does not contain any additives or use any yeast to rise. Instead sourdough uses a starter culture which makes it rise and gives it a sour taste. 

A sourdough starter is a wild ferment of water and flour which contains yeast and good bacteria. 

Sourdough starters can be used for much more than just bread. Some of our favorites are scones, waffles, crumpets and crackers! Check out our blog for sourdough uses and recipes!

Our sourdough starters take well to lots of different flours. In house they are fed mostly organic stone ground flour and organic spelt flour but you can titrate this starter onto a flour of your choice.

We love this sourdough starter

Amazing purchase, we are very happy.
I decided to use a scale instead of a cup.
I use everyday around 250 grams for baking and I keep 150 in the jar.
150 sourdough + 150 water + 150 symbiota organic flour.
Thanks @ Symbiota team!

Super pleased

My starter dough arrived virtually overnight. I became the learner of making sourdough bread then and there!
My first loaf turned out fantastically - I surprised myself but with the instructions being very clear and with following them to the letter, it all came together and I continue to turn out fabulous loaves!
I’m about to make buns with the discard!

Already made my first Loaf. Instructions were a bit confusing but the symbiota team were very helpful over the phone.

Glad to hear you have made your first loaf. Enjoy! If you have any further questions, please feel free to reach out.
