I am not sure if you mean by "mixed" after 12 hours that you fed it again. It's not clear how you fed it after the second step - 1 - 24 hours: reduce and double 2 - 12 hours: activity, reduce and double again 3 - 12 hours: no more activity - not clear if you fed again 4 - 24 hours: no more activity - not clear if you fed again What's somewhat strange is the separation/floating you describe after step 2. If you have sour smell and nothing or little putrid/disgusting/strange smell, you are in business and need to keep nursing. In your case, that would have been after 36 hours. Somewhat correlating with: http://samartha.net/SD/MakeStarter01-5.html The tricky part is to recognize oversouring and take countermeasures i. e. stronger dilution. If it's happening and you don't keep going, it gets quiet. It could be that the LB's are not doing much gassing, but are active and kill everything else off and then shut down themselves. It's often not clear if it's undernourishment or oversouring and the way out of it is to go both ways - split it, use one part with strong dilution - 1 : 10, the other part go on as before. Also, stirring helps moving the nutrients around, get some air in (the critters like it) and get a control on gas production. It could well be that your quiet mixture comes up again, when you do a strong dilution and continue feeding. Growth rates are geometric in the area of doubling maybe every 1 1/2 - 2 1/2 hours, so going at full blast, you can have like a 64-fold increase in 12 hours and a 4096-fold increase in 24 hours if no hindering factors (souring, nutrient depletion) come into play which happen Maybe it gives you some ideas what could be going on. In any way - congratulations to trying this. Can be a rewarding experience. As for the other responses: Kenneth: flour sterilized? - Hardly because it was active and smelled sour. Mac: suspected virus - Nice idea. Souring by LB's is pretty established in our biosphere. Maybe DA can tell you more about this. He claimed to be unable to keep a starter going for a longer time and need to get regular updates - all to be taken with grains of salt from that corner.

If the culture environment is dryer, as in dough-like, you can avoid most, if not all, of the opportunistic growth from undesireable bacteria. The appropriate microbial culture comes with fresh grain. It is the basis of a symbiotic ecology which makes makes sprouting efficient. Your gut carries bacterial for the same purpose: to make energy conversion efficient. Too much water is not a natural state for sourdough culture(s). Samartha has mentioned on several occassions that stirring to oxygenate is important. Why might this be? Too much water? All of the comments about hooch indicate bad culture practices, wastes are inbalancing the culture process. There is nothing in the grain-to-mature-plant cycle that works under water. Grain rots in a flooded field. So does flour under water. Will |

First, though the yeasts do, indeed, come "with fresh grain" it is my understanding that the lactobacilli do not. It is my understanding that they seem to come from the baker. Also, when you say of the "culture" that "It is the basis of a symbiotic ecology which makes sprouting efficient." I don't get the connection between sprouting, and generating a sourdough culture (even leaving aside the issue of the absence of LB on the grain.) Similarly when you say "There is nothing in the grain-to-mature-plant cycle that works under water." That would certainly seem to be true, but how might that fact be connected to the growth of a viable culture for baking? It seems rather like suggesting that we cannot make rubber from latex because there is nothing in the cycle of the life of the Hevea tree that involves the shedding of the sap... And finally, in response to Samartha's suggesting stirring, you ask "Why might this be? Too much water?" but, again, I don't get the connection. Why would stirring be related to the amount of water? I certainly agree with your comment that "the comments about hooch indicate bad culture practices" but don't see any (direct) connection to the issue of the amount of water in the starter.

Without the water layer, the starter would outgas cleanly. My argument isn't that water is bad. My argument is that too much water is fundamentally inefficient. When I start a culture with a moistened ball of dough, I do not have to worry about competing "bad" organisms fooling me for a couple of days. And I don't deal with hooch or watch the bubbles moving through it. The smell of a ripened piece of dough has very little in common with the smell of submerged starter. That should tell us something. ----- Will |

Absolutely untrue IMO - yeasts and LB's need moisture and if it's just moisture, many other organisms can grow in moist flour - anaerobic, molds, fungi, bacteria, bacilli - you have it. I have a research article where the interaction of sourdough specific organisms with flour specific organisms is being looked into. It's from 1988 and may not be fully up to date any more but for sure holds still some water. They looked at 13 flour specific critters and 10 LB's. Best in retarding growth of bacteria and bacilli was LB leichmannii and LB SF was second worst - apparently doesn't need it any more when making home in sourdoughs. Interesting, the organism from that bunch which is most tolerant against lactic and acetic acid is a streptococcus faecalis. You can guess by the name where it is coming from. Not really plant specific I would say but it's regular home may not be abundant with water either - most of the time. Escherichia coli is in that collection as well. (googled: Escherichia coli O157:H7 is an emerging cause of foodborne illness. An estimated 73,000 cases of infection and 61 deaths occur in the United States each year.... E. coli O157:H7 is one of hundreds of strains of the bacterium Escherichia coli. Although most strains are harmless and live in the intestines of healthy humans and animals, this strain produces a powerful toxin and can cause severe illness.) I think that feedlot cows can have it and sourdough kills it if it's in the flour. The main factor of inhibition they figured in that research project is the acidity and mature sourdough does not get affected by the new critters in the flour because of it. >The appropriate microbial culture comes with fresh grain. Doesn't necessarily need to be fresh - the organisms seem to hang around. >It >is the basis of a symbiotic ecology which makes makes sprouting >efficient. Your gut carries bacterial for the same purpose: to make >energy conversion efficient. Too much water is not a natural state for >sourdough culture(s). Says who? What would be a "natural state" of sourdough? Is there sourdough occurring in nature without human interference? Maybe in a dove crop - who knows? Doesn't really matter here. And what's "too much water"? Continuous SD starter productions or industrial SD dough production is run with high hydrations so it can be pumped. This would not work if the LB's and their mates were water shy. They work anaerobic and don't care how wet it is as long as there is food around and the temperature is right AFAIKS. > Samartha has mentioned on several occassions that >stirring to oxygenate is important. Maybe under some circumstances but surely not necessary. They get an extra kick but can do very well without it. Unless you are pursuing a particular goal, I would not call it "important" - helpful under circumstances, maybe. >Why might this be? Too much water? >All of the comments about hooch indicate bad culture practices, wastes >are inbalancing the culture process. Who makes a problem about hooch - it happens, so what. What's bad about it? In earlier days it was valued in situations. I see hooch as a protection layer. If the culture dries out, molds grow, hooch prevents this. That's definitely an issue with drier cultures stores over longer periods in a fridge. I'd say wetter is better. And who knows what taste effects a bread can get when it's made with a starter sitting in the fridge for two month under 1/2" of hooch. I think you are really depriving you of great adventures if you exclude hooch from your sourdough live. > There is nothing in the >grain-to-mature-plant cycle that works under water. Grain rots in a >flooded field. Doesn't this make you wonder why it doesn't rot, i. e. smell rotten in your moist starter? And rice isn't a grain because it grows in water - right? >So does flour under water. I think that it would get eaten when dropped into the water - fish or smaller living things may really enjoy it.

You may be fermenting something else - some kind of alcoholic beverage. Bubbles rising to the surface? You know, this volume measuring business is kind of vague. I measure a cup of flour with 137 g and the cup with water 227 g which gives a hydration of 166 % - that's high. If you go 1/2 cup water with 1 cup flour, you would have 83 % hydration with my measurements, that's better. With the smell - you'll know when it's right. If you do full grain starters, the smell sensations can be very entertaining. >OTOH, my first starter attempt, which was from a dough ball of unbleached >flour, had the aroma of cheese.

Initially, you have all kinds of crappy organisms growing, there is really no need to be anal about being very clean. Covering so flies don't get is is probably a good idea.

Well, the LB's stop when it get's too sour - the yeasts probably too. Everything stops if it gets too sour and eventually dies. Symptom: No activity. The other situation is low germ count, nothing or very little growing. Symptom: No activity. If you look at it, you don't know which situation you are in. The way out of it is to cover both. With the oversouring, the new addition in feeding needs to offset the sourness to bring it into a range where the organisms can grow again. Often doubling the flour is not enough. Tripling works most of the time. With established starters, and you kind of knowing what they are doing. When starting one and you don't know where you are, a stronger dilution can be helpful. >Based on your suggestion, I've divided the starter into three batches. >The first is a continuation of the original, using whole wheat flour.

Although your bubble water is a mystery. Also, you are using 1 cup feedings - that's over 100 g and you'll get a lot of material that way. I am sure you'll work it out. Enjoy!
