How much sourdough to keep on hand?

Toast

I'm a pretty casual bread baker, 2 or three times a month, 1 loaf at a time. I'll be storing in the frig. So for someone like myself whats a good amount to keep on hand?

 

Your frequency of baking is about the same as mine, and storing the starter in the fridge works very well for me.

I adapt the quantity I keep according to my recipe. In general that means keeping roughly a ninth of the amount of levain called for. That way, I can take it out of the fridge the day before I want to bake and feed it 1:1:1 (no discard) to wake it up. Then 8 hrs or so before I want to actually use it, do a further 1:1:1 (again, no discard) which gives me precisely the amount of levain I need. Finally, just before I add the fully developed levain to the main dough I take out one ninth of it to be my next starter. Simples.

Andrew Whitley calls this a ‘total refreshment’ approach, because you effectively get a completely refreshed starter every time you bake.

In practice I increase the amount of levain ‘in the recipe’ by about 10% in order to compensate for the ninth I’m taking out - but it doesn’t make a great deal of difference to be honest.

That’s it, really... the only exception is that if I haven’t baked for more than 2 weeks I take it out of the fridge and to a 1:1:1 feed WITH a discard, then leave it out for a couple of hours to give it a chance to recover...

 

Take the time to save a couple of teaspoons of your discard, feed it and give it a two or three hours to develop, then freeze it as an emergency backup.

A 60% water stiff starter will keep longer between feedings. A half pint jar is plenty.
