Hi Jeff:
If you ever get bored or have the initiative perhaps you could re-borrow a portion of the start you gave to your friend. Since she is close, perhaps one grown to its second (or third) stage and nearly ready for bread making (plus another mother). It would be interesting to see if you get tangy bread from it following your normal recipe. Moreover, how long the new mother continues to be so after coming home with you. {I have heard that cultures can drift, too. In contrast, I have heard that they are stable and do not change -- many are hundreds and some purported to be thousands of years old. Finally, I have heard that there is a small probability that the indigenous microbiology is heartier in certain conditions than that in some cultures and thus can get a foothold. I have read mention of evolution where the culture adapts to its food source and environmental conditions. I don't know what is true. Yet, I have also heard (and believe) that the techniques of the baker and the environmental variables, temperature, humidity, proofing times, etc. are hugely responsible.} Ray ----- Original Message ----- From: "Jeff Miller" > To: "'A ported usenet news group'" > Sent: Monday, September 11, 2006 10:42 PM Subject: yeast/bacteria balance > My understanding has always been that no matter where the culutre came > from, > within a couple of months, your local microflora will take over in your > starter.

Here's my two cents. Cultures stored in the refrigerator tend to be milder. I suspect this is so because the yeast side of the population mix is more tolerant of lower temperatures and also its growth rate is stronger below 85 F than LBs. So when you refresh the culture from cold storage... what grows first? Yeasts. When you return the room temp. culture to the refrigerator what stops growing first? LBs. It is logical that over time, with repeated cycles, the yeast side will dominate the stater. My answer to this has been to store starter as a small dough ball. And I keep it in the cellar, not the refrigerator. The dis-advantage to dough ball storage is that at refreshment time, you have to break the ball up into little pieces and rehydrate. OTOH... nothing (especially the water) is starting off at 38 F. so there is less opportunity for the yeasts to get a head start. When I put the culture away, a spoonful is kneaded with flour back into a dough-ball. This dehydrates the culture (but does not dry it) and drastically slows the subsequent growth rate. My starters are maintained on freshly ground white wheat berries... but red wheat or rye works equally well. And they make either sour or mild bread depending on the inoculation ratio and the temperature employed for dough building. An aside... if your bread is milder than you like... try adding a small amount, like 80 grams, of cooked barley or oat mush to the sponge stage. I specify oats or barley since the outer seed hulls are removed before sale, and the remaining inner ones are soft. Moreover... after cooking this remaining hull is largely reduced to mucilage. It will not interfere with your rise or crumb. What you are doing is boosting maltose (Google saccarification). This enhances the souring possibilities. |

If you do it like I do it, namely by totally refreshing a small amount
of starter for each bake, and allowing plenty of time for the rise, approximately the same balance will be achieved for each bread batch. It matters very little what was started with, as long as it had the right living organisms in it. You can futz around with the starter culture as much as you like, and unless you are baking it directly, or eating it raw, it changes nothing. -- Dicky |

Maybe I'm not understanding your intention. But Since being inspired by your methods I've been able to make much better bread, by changing the way I feed the starter and then the dough. Are you talking about (futz around) where you store and how you store the starter? Jim |

Dick is not always terribly straightforward. Dick seems to feel that many people obsess over the starter. He calls it "startermuckery." People who collect dozens of cultures - but use them so infrequently that they can't tell the difference between them, or really know how this culture should be handled. In the end, unless you are a microbiologist, it's not about the starter, it's about the bread. The starter is just the way you get there. Are starters different? Sure. Does it really matter? Usually, no. Spending too much time messing with the starter is usually a waste of time. Instead, you would be better served by making bread Mike |

There is a small minority here that automatically assumes that everyone else is utterly ignorant. Ignorant at a fundamental level about how things are not just some of the time but all of the time. The irony is that they have thrown the baby out with the bath water and hold the exact same view only in reverse, the other side of that exact same coin, as it were. In refuting the permanent and inherent they have become equally ignorant nihilists. I realise that these days there's a growing majority that think that all things are inherent and yet by contradiction think they are created by some being a few thousand years ago. But not everyone thinks in these terms and not all that follow a 'religion' think in these terms. Moreover there are many so called intellectuals who at a deep level think in these terms but profess otherwise. The important thing to remember though is you cannot assume just because someone hasn't been making sourdough for fifty years that they are utterly and fundamentally ignorant about how things exist. Does having countless starters, experimenting with your starters, mean you are stupid or curious? How is one, new to sourdough, supposed to know what is truth and what is 'old husband tales' if one doesn't check out a few things for oneself? Checking things out is quite smart in my book. I can fully appreciate Dicky's frustration when he has gone to so much effort to share information with people to have it thrown back in his face or just thrown aside along with the rubbish. But If one is really interested in sharing good information one has to be consistent. One has to be respected by many. I remember having a discusion with Samartha he seemed only intent on 'winning' the discussion taking it so far that he contradicted what he'd said earlier. A new person writes off that so called teacher straight away as untrustworthy. You say 'would be better served by making bread'. Isn't treating your starter properly not part of the process of making bread? And with all the crap about how else is someone new to sourdough supposed to get to who is telling the truth without some personal investigation? When you don't know anyone at all in the 'community' who do you ask to get the answers you can rely on. Who can you ask 'who is a good person to ask'. The majority of people these days prefer to put their trust in charm rather than reason. I respect Dicky for cocking a snook at this. But he goes too far. We aren't born with total knowledge of all things. We have to learn. Some do want to learn. Despite whatever I might say, I always have an open mind and love to be proved wrong. How else does one learn new things? You know, if people just came here and followed exactly what , say, you suggest Mike, they would be equally guilty of all the things that Dicky seems to be having a pop at. It's only by testing and investigation of the 'teacher' that you can then say, 'well, I don't understand why, but he says it's right so I'll do what he says and then perhaps I'll come to understand later'. It's taken me a few years to cut through all, or at least some of the crap and know what matters and who else knows what matters. I know Dicky is one of these few that knows, and there's a few others. But since it's this ignorance that annoys Dicky, wouldn't getting rid of the ignorance by not giving so many contradictory replies serve this better. If you see Dicky's 'confounding of newbies' as being without some error on Dicky's part then surely that, with all respect, makes him no more than a troll as some profess. I come here with the motivation to help, to learn and hopefully to dispel some of that deep seated ignorance. It's the ignorance about how things are that is the real problem not enquiry or holding some bad information. Jim |

Thinner, thicker; warmer, cooler; longer, shorter; English, not-English, glass, ceramic; capped, not capped, stirred, shook, sat, etc. Etc., etc., ... Not to say that some day, some resourceful starter diddler, will not succeed to reinvent this particular wheel in some small and possibly interesting way. However, a good sourdough fermentation will always start with the amplification of yeast activity, and end by waiting for the flavors and acidity to develop. Or I will eat my oven mitt. That's not to mention rye sourdough. There one must be respectful, though remaining always suspicious, of the extensively-reported procedural complexities. (Heck, if anybody could make real rye sourdough bread, what would we do with all of these picturesque old-world bakers?) -- Dicky |

You're not saying that you can take an old unfed starter out of the fridge and make great bread with it are you? Because that would be the same kind of thinking that says an English starter is better than an American. If the qualities of the bread are inherent to the starter then it doesn't matter what you do to it, it will always be good. If the qualities are not inherent, and nothing can have inherent qualities, then it does matter what you do to it. Which bits matter most or not at all is the only thing worth considering. I know from your methods in your instructions doc that you think what you do to the starter as far as feeding goes matters. Otherwise why would you suggest a feeding regime. My experience tells me that feeding matters. I agree with you that folks going on about their crock, and their 'active' starter they just got in the post is annoying. Because it is the kind of thinking that posits inherent qualities on some or all parts of the starter process. It's just ignorance. But you can't chuck the whole thing out and say nothing matters at all, that's just the other side of exactly the same coin. Jim |

Hi Will:
Thank you for a helpful and informative reply. Unfortunately, in Florida we seldom have cellars <g>. Yet, within your reply I am interested in the growth rates of the yeast and LB's. I have perused some of the information on the growth curves including the Michael G. Gänzle, Michaela Ehmann, and Walter P. Hammes' study (http://www.pubmedcentral.gov/article...i?artid=106434 -- not that I would pretend to understand most of it but I get the drift that 85F is a good compromise temperature to encourage growth for both the LB's and yeast.). Coincidently, I have been looking at the Detmold 3-Stage Process discussed on Samartha's site (http://samartha.net/SD/procedures/DM3/index.html ). I note that (if I am reading it correctly) his starter hydration varies from 140 in Stage 1 down to 66 at stage 2, then back to 90 at Stage 3. While the Detmold 3-Stage Process is for use with rye breads, does hydration have any affect on either LB or yeast growth rates in wheat breads? That is, is there any difference in LB/ yeast growth rates in a 150% or 200% hydration culture versus a 50% to 60% hydration culture, or even less at the same ambient temperature? Are you storing your cultures in dough balls simply as an effort to level the growth rate playing field between the LB's and yeast, or is the extremely low hydration a factor? I have read anecdotally that bread made with a chef (meaning a lump of old dough, in case I am using the terminology wrong) are more ______ {choose one or mo sour, complex, assertive, tangy, etc.}. I have never tried it, but it seems that is close to what you are doing. So far, I did not find, except perhaps an indirect reference by Dick A in a post, where varying hydration during starter development has been discussed. I inferred from that post (Dick A's) that normal sourdough hydration percentages did not have any significant effect on growth rates. However, there was no mention of hydrations in the 150% to 200% range nor in extremely low hydration rates. Again, thanks to you and everyone else for some very helpful information. Regards, Ray |

I did note a prevalence of wine coolers though. That will work.

The Ganzle material takes some time. There's a lot there. Different pieces become clearer as various baking issues present themselves. You might also look at the Ganzle/Wing discussion that Samartha has copied as well. It covers a lot of the same ground... but is less dense. > While the Detmold 3-Stage Process is for use with rye breads, does > hydration have any affect on either LB or yeast growth rates in wheat > breads?

In general the more water, the quicker the fermentation. The Detmold process is also managing ionic balance. This affects pH and acid loads. > Are you storing your cultures in dough balls simply as an effort to level > the growth rate playing field between the LB's and yeast, or is the > extremely low hydration a factor?

I have never tried it, but it seems that is close to what you are > doing. I started the dough-balls because I was tired of hooch. It simply seemed like a cleaner way to go. And I kept them in the refrigerator. At the time I was running 5 starters, using two a week. So the down time for any particular starter was 2.5 weeks. By moving to dough-balls I eliminated the water trap effect. I was also building and discarding starters frequently and noticed that they would start "sharp" when new but become mild over time. I knew that big bakeries like Acme in S.F. did not refrigerate starter, they used it 24/7 and they maintained it in expensive bio-reactor style fermenters. Since it seemed logical to move from the refrigerator, I moved the dough-balls to the cellar. The senescence stopped. They stayed sharp. It is not exactly like the old dough technique. If you are interested in that, Jeffrey Hamelman uses preferments extensively throughout his book. My starter dough balls are very small, no bigger than a ping pong ball. Dick Adams alluded to starter build size earlier in the thread. Staying very small, 20--40 grams, and building each time is key to healthy starter and balanced microbe populations. > So far, I did not find, except perhaps an indirect reference by Dick A in a > post, where varying hydration during starter development has been discussed. > I inferred from that post (Dick A's) that normal sourdough hydration > percentages did not have any significant effect on growth rates.

I think the most important single variable however is inoculation percentage. That is an art. My practice now is to build small, thick sponges from very small amounts of starter. So I'm using about half my total water for the sponge. I complete the balance when I build the dough. That way the acid never gets away from me, it's well buffered in the sponge and it's well diluted going into the dough. |
