Which type of starter will be most beneficial?

The question of stiff vs liquid starter has recently been bought up here on Yumarama and since it was discussed over on Mellow Bakers previously previously, I thought it wouldn’t hurt to carry that conversation across to the blog as well.

Someone recently asked what the point was between using stiff and liquid levain, specifically in Jeffery Hamelman’s book BREAD. I pondered and, in effect, could not come up with a solid answer for myself, primarily because I haven’t really dabbled with a stiff starter very much. But still, why DOES Jeffrey ask for a stiff starter here or a liquid (he prefers 125%) there? In other words, what are the benefits of each, in his view?

So I figured I’d go to the source and ask.

Hi Jeffrey,

Someone recently brought up a question I was a little confused about and figured I’d go to the source to see about an explanation.

In the book BREAD, you mention it is possible to switch one type of starter to the other easily enough – and it is. However, I’m unclear as to why one recipe calls for stiff starter and the other liquid and, more specifically, what you expect each to bring (or not bring) to the table. If it’s merely a matter of making a starter wetter or dryer just before using it, particularly since you start your levain with such minor amounts (for the home scale, at least) I am not understanding the reasoning for using or keeping two kinds of starter.

Perhaps in a bigger scaled bakery volume it makes more sense.

Can you please shed some light on this issue?
Do you keep both types of starter active at all times?
Do you think a home, weekend baker would see any advantage to keeping both types or is “turning” a starter at the last minute adequate?
What differences do you see a stiff and liquid starter bringing to a sourdough recipe?

Thanks so much for any insight you can share.

Hello Paul,

Thanks for writing and for asking your astute questions. Feel free to quote me on the answers.

I’ve maintained two starters for a number of years: a firm German-style rye culture (made the third week of August, 1980), and a liquid levain kept at 125% hydration (it’s about a dozen years old). We use the rye for all our rye breads, and the liquid is the base levain for all other breads. We convert this one to stiff or to whole grain as needed, but only for the build(s) that will then be used in a final dough mix, not in order to continue perpetuating stiff or whole grain starters. These methods are practical and not terribly labor intensive, and we use them successfully at the King Arthur Bakery every day. By the way, our starters get two meals a day, seven days a week. On Christmas, New Years, Easter, and other holidays when we are closed, they receive one meal, as a baker is in for a short time on the holidays in order to make preferments and do some other things to enable us to open again next day.

Certainly, for the baking of just a couple of loaves or so, there is no reason to keep more than one starter. While it’s good (and important in my opinion) for today’s ever more skilled bakers to know how to convert a liquid starter to stiff and vice versa, there’s no reason to necessarily do that, because as you pointed out, the amount of mother culture going into the builds is very small. Small adjustments in flour or water will compensate at the time of the build so that levain consistency is correct. And if one maintains just a liquid or a firm white culture, he or she can easily give a couple of meals of rye flour in advance of making rye bread–that will suffice; there’s no need for occasional rye bakers to perpetuate a rye culture.

Why do some bakers prefer to maintain a liquid levain culture and others a firm levain? On the face of it, I’d say it’s mostly about personal preference–some bakers prefer the ease of mixing a firm ball of dough, while others find mixing a batter consistency starter easier. As for all that science about acetic acid developing more favorably in firm environments and lactic acid in looser ones, that’s all good and true, but it’s ultimately up to the baker to determine the flavor of the bread. For instance, what if I kept only a liquid levain culture and wanted to make a bread on the acetic side, but didn’t want to convert to a firm levain? I could do a few things to encourage more sour flavor: I could preferment a higher proportion of the overall flour, I could extend the bulk fermentation somewhat, and of course the easiest way would be to retard the shaped loaves overnight. All of these would encourage more acidity in the final loaves. Treating things in the opposite manner would give milder results. Aren’t we lucky that after all we are the ones who determine the bread’s outcome by our cumulative series of engagements with the dough?

I hope this answers your questions adequately. And I hope you and your colleagues are continuing to enjoy both the learning and the resulting breads!

My best,
Jeffrey

Aside from the general info he expanded on here, it is good to see a bit of explanation on how to accent the bread’s acid content in several different ways in such a concise manner.
