Starter Questions

How do I increase the quantity of my starter to bake 12 -18 loaves of rye  over a two day period, every week, using 1/2 - 1  cup per loaf?

Is my math correct?  If I add 1/2 - 1 cup of 100% hydration starter to 80% hydration dough it shouldn't alter the dough's hydration.  Thanks in advance.

Quantity of 80% hydro dough?

weigh the 1/2 - 1 cup starter I can calculate the total/final hydration.

I must be missing something.  If a cup of 100% starter (equal parts water and flour) is added to dough, shouldn't the dough's hydration remain the same?

If I understand correctly your starter is 100% being equal weights of flour and water, yes? And the addition is 80% water to 100% flour, by weight, (water=417g & flour=521g) then there will be a difference in hydration. If you're using a 30% (I'm guessing here) of SD pre-ferment (by total flour weight) that equals 210g of flour and 210g water

Adding them up would equal 731g flour and 627g water at 86% hydration.

Got it!  Thanks.  I have to reduce the starter's hydration to 80% (210g flour to 168g water, using your estimate) to maintain 80% in the dough.  How about my other question about increasing the quantity?  It may be easier to use a separate starter for each baking day.  What do you think?  Thanks again.

either change starter hydro or add flour to final mix. It's a good idea to refresh the SD daily if using it daily. Remember to make enough starter to have enough leftover for the next batch.
