How to: Easily Make Your Own Sourdough Starter (with video!)

You can make your own sourdough starter at home, and we're here to help make it easy.

Here's all you need:

1 kitchen scale

1 glass jar - We use a Weck glass jar; it's the perfect size and its straight sides make it easy to access and stir your starter!

1 stir stick - A jar spatula works particularly well if you aren't going to use your finger :)

Flour stone-milled flour is best as it retains all of the good yeast and bacteria to cultivate in your starter :) This is a great cost-effective option for your starter.


We put together this video series just for you all. Here is the 1st video:

 Our favorite starter flour is TAM 105. Find it right here.

New Favorite Shirt

This is my new favorite shirt. They are very soft and comfortable, although they are a tad bit long for my taste. Not a big deal by any means - I've had it two weeks and already worn it 3 or 4 times.

Yecora Rojo

I bought the Yecora Red to make some artisan sourdough & it came out so delicious. It has a wonderful nuttiness with great complex flavors. Just love it. Can’t wait to try some of the “00” sifts.

Just what I wanted!

After having blue cornbread on a trip to Colorado, I looked everywhere for the cornmeal to make it after returning home to Boston. Luckily I found it through Barton Springs Mill, and it arrived a few days after ordering. I've already used it several times for several different recipes. It's awesome, and exactly the flavor and quality I was looking for. Highly recommend!!

What a taste

I baked already two sourdough loafs with the flour and the taste and smell is amazing.

Helped with colic from breast milk!

I have three kids and breast fed all of them and I always had to watch my wheat intake otherwise my babies were gassy. I thought for whatever reason it was the gluten but then I learned that it’s actually how the wheat is made and what pesticides were used that upsets the babies and the mamas through the breast milk. So this third time around I have been searching for an organic wheat flour that wouldn’t upset my 6 month old’s tummy through the breast milk and I say success! I have baked muffins and cakes with this flour and have no complaints! If you want a fluffy result I’d recommend sifting as I would with any flour. Very happy and will buy again
