To start and activate a sourdough starter follow the directions below.

Place starter in a vessel.
Add 45 g each of all-purpose flour and room-temperature water.
When the starter has roughly doubled in volume, it's likely ready to go.
If it doesn't float after 24 hours, add more flour and water (equal parts), stir again, and wait.

Simply put: a sourdough starter is a live fermented culture of fresh flour and water.

Once combined, the culture begins to ferment cultivating the natural yeasts found in our environment.

A small portion is added to your bread dough to make it rise.

Commercial yeast IS NOT required.

Using too much sourdough starter will cause it to consume the nutrients and sugars in the dough mixture too fast.

And when this happens there will be a lack of bubbles that should be there due to fermentation.

The best flour for sourdough starter is rye flour.

Although any flours will do such as spelt, einkorn, rye, and wheat.

You can mix different flours with sourdough starters since the sourdough starter needs the starch and any flour will contain the starch the sourdough starter needs.

You can revive a dead sourdough starter.

To revive a dead sourdough starter follow the below directions.

Feed 1/4 cup (2 ounces) starter with 1/2 cup (2 1/2 ounces) all-purpose flour and 1/4 cup (2 ounces) water twice daily (approximately every 12 hours) and let it sit, covered with plastic wrap, at room temperature.

If you don't feed your sourdough starter the sourdough starter starts to smell like alcohol and you will also find that the starter loses its vibrancy and doesn't get too bubbly and active after a feeding.

Don't worry, you can always get the sourdough starter to recover.

You can leave your sourdough starter on the counter at room temperature as long as you continue to feed the sourdough starter.

The sourdough starter can either be kept at room temperature or in the fridge.

A sourdough starter that is stored in the fridge will only require feeding once a week to maintain it.

If you use your sourdough starter every day, keep it at room temperature.

Follow the feeding instructions and then leave it at room temperature.

Every morning or every night, discard half of your starter.
Feed it and let it sit while it eats the flour.
Bake with it when it has doubled in size.

As always, how long this takes will depend on the vigor of your starter and the warmth of your room.

Sourdough starter does improve with age overtime and the longer you keep the sourdough starter the better the flavor gets.

However after about 10 years the sourdough doesn't get much better with age and there won't be much of a difference between 50 or 100 year old sourdough starter and the 10 year old starter.

Sourdough starter can be kept for many years without going bad and if you keep the sourdough starter for up to 10 years then the flavor improves.

But after the 10 years there's not much improvement in the flavor or much improvement in the sourdough starter itself.

But you can use very old sourdough starter and still get great results.

Most people use the sourdough starter well before 10 years but I've heard of some people keeping it for over 50 years.
