A few months ago I decided to begin maintaining a starter. To that point I’d avoided it, partly because I didn’t want Another Living Thing to maintain, partly because the idea of throwing away starter seemed wasteful, and partly because it just felt like it was going to be a messy and unnecessary hassle.

The flip side of maintaining a starter would be that it would allow for more interesting things to try with breadmaking. It would also add another “color” to my available “palette”. The end product could be better tasting, better for us, and keep longer before spoilage. Ultimately I read enough intriguing starter-based recipes that I decided to give maintaining a starter a try so I took the leap.
I wanted a starter recipe that wouldn’t consume or waste much flour. I also wanted a starter recipe I could mostly ignore after it was finished. I settled on Ken Forkish’s Levain recipe from Evolutions In Bread. The entire process requires one week and 550 grams of flour.
Creating the starter is pretty simple really. Weigh the container and write that number down. Every 24 hours some amount (by weight) of the contents of the jar will be discarded and then the container will be fed a small amount of fresh water and flour. I made the decision ahead of time to mill all of the whole wheat flour I was going to need, 250 grams total. That way I wasn’t getting the mill out for the first few days when it was time to discard and feed. The process felt very easy and pretty bulletproof — I think that fresh milled whole wheat contains enough nutrients and enough bacteria/enzymes/assorted microbes and whatnot that kicking off the new tiny ecosystem basically took care of itself.
The recipe it calls for 250 grams of starter as the end product. I “shorted” the final feeding and I didn’t see any adverse effect. I did that because I wanted to be able to pull a smaller amount out of the jar each week and still keep things fresh and lively with smaller feedings. If I want to build up a large quantity of starter it takes a little longer but I’m fine with that.
I maintain 150 grams of starter in a 393 gram jar (weighed with no lid). Each week I take a small spatula and scrape/pour out 100 grams for bread baking. I then add 50 grams of bottled water and 50 grams of bread flour to the container, scrape down the sides, and stir it up. I put the lid back on and let it sit on the counter for 1-2 hours, until it starts to show some signs of life. Then it goes into the back corner of the refrigerator for another week. I store yeast in a tupperware-type container on top of the starter. Everything is in one place and ideally staying fairly cold.
As for the container – it became clear pretty quickly that straight sides are a good thing and a threaded jar is a bad thing. Straight sides because it’s much easier to get into and scrape down the jar when there’s no “neck”. Threads just gather crud and rapidly clog. I purchased a 6-pack of the Weck 743 jars and split it with a friend who was also making a new starter. (At the time the total cost was ~$6.50 per jar for six.) I use them without the gasket. They’re nice somewhat heavy jars made of thick glass. The lid just sits on top and it’s plenty secure.
Final thought: Evolutions in Bread is a great book. Highly recommended.
