But note, Rossco, you underfed it significantly - so it probably peaked in only four or five hours. It will need to be fed sooner now or it will begin to decline.

Hang in there.

Part of why I am pounding on this is that it seems to be important to get the starter really healthy at some point so it can truly take over and push out all the bad stuff. So feeding reliabliy and consistently until it is robust is important. Once that is accomplished the bad stuff has a hard time getting back in and you don't have to be so careful. As I indicated mine gets tired - no problem. Just give it an extra feeding to perk it back up.

I don't know about you guys, but I find wittnessing the birth of a new sourdough starter really cool. Kind of like seeing a dome close in, its one of those special moments....

Good luck Rossco, may your starter live long and prosper!

Thanks for the positive words Frances..

Jay - have scaled the starter down to 100 grams and added 50 grams of flour and 50 grams of water and all looks good.

Will feed again tomorrow morning.

Will that have to be 100 grams water and 100 grams flour to match the 200 grams that the starter currently is?

Right, Rossco. If you don't scale it back by removing 100 grams of starter, you should add 100 grams flour and 100 grams water. (Since you have 200, if you toss 100 of starter you can use 50 and 50.)

You gain nothing by not tossing unless you like using sourdough starter in pancakes and stuff like that for you can grow it back up in a couple of feedings. Like I said earlier, there are people who only keep 10 grams or so of starter and feed that. (That's too laboratory like in size for me! I want something I can see!)

Excellent Jay - much appreciated. I will cut it back in the morning then and will continue to keep it at 100 grams in future. It definitely seems a manageable amount.

I will check back for your recipe but what is the general amount that is needed when baking a couple of sourdough loaves??

Part of why I keep 200 grams is I start my bread batches with 100 grams. When the house is in the mid 70s I do a 4X expansion (100 grams plus 400 grams (200 flour and 200 water) so I then have 500 grams) around dinner time and leave it out all night. It will take about 12 to 13 hours to have peak activity. Then I do another 4X expansion (about 1250 flour and 750 water, i.e. add 2000 grams to 500 = 4X). And 45 grams of salt (some would say 30 is right but I like a little extra). I do all the mixing by hand. I sent pretty complete details a page or so back.

The recipe above makes 2.5 kilos or about 5 pounds of bread. A simple way to reduce the final amount is to reduce the final expansion to 3X and add 1000 grams flour and 500 water which will give you about 4 pounds. If you want less, I would drop the beginning starter amount to 50 to 80 grams and simply ratio down the additions. I would NOT reduce the first expansion ratio of 4 because the yeast activity will peak too soon and the preferment will be a bit lethargic the next morning. Going less than about a 3X final expansion doesn't give the yeast enough to do and is a bit weird.

And finally, if the kitchen temp is in the high 60s the first expansion can be 3X because at that temp it will just about peak in 12 to 13 hours and be ready to go the next morning.

Note: All the above is based on MY yeast and sourdough but most sourdoughs are pretty similar in activity level and temperature response so the guidelines should be about right. Also, the above is for OPTIMAL results. Until you have been doing this a while you probably won't notice much impact from having the first expansion peak a bit early or late. So I would say base the expansion ratios on your kitchen temp (more or less), adjust the starter amount to how much bread you want (25 grams or so for one 1 1/4 lb. loaf, 50 for two, 100 for 4) and go for it!

Good Luck!
Jay

OK sounds good ... will feed again shortly and then get things ready for a bake tomorrow...

This process is certainly a science, making the results that much more rewarding as Frances suggests!

Think of your starter as a pet that will return your love and attention with great bread!
