After reading the comments about mold in primary fermentation stage; we
started 4 gallons of apple cider but the temp was bad and we had green mold on top of the cider (just apple juice let to ferment by itself, no yeast or other additives). We ended up throwing it down the drain, but could we have saved the juice by adding yeast??? Any comments/help would be appreciated. We're new at all this stuff! Cathy |

Mold usually takes several days to take hold, if you would have used one packet of wine yeast the juice would begin fermenting sooner and would have made the environment less hospitable to mold.

Kathy,
Bacterial spoilage can be corrected by adding sugar and re-fermenting. I got this advice from a reputable winemaker. If wine has bacterial spoilage either add it to next years batch or add sugar and referment. Obviously the re-fermented batch will be stronger but it will be drinkable. Use Champagne yeast if alcohol is already present. The first time I used this advice was a couple days ago and it worked great.

Why is it not good advice? I'm not saying she shouldn't add yeast to
ferment. I'm saying that spoiled wine can be fixed. What is the worst that can happen, pouring it down the drain anyway? Bob On Oct 25, 8:05 pm, "Paul E.

The two Paul's in this thread would make good Republican Presidential
candidates. Instilling IRRATIONAL FEAR into anyone who ever came across mold or a bad smelling wine. On the contrary, there are no known pathogens that exist in wine. It's the reason the Board of Health exempts wineries from reqiurements of section 20C. Has anyone on this board heard of anyone getting sick from bad wine? Anyone? Frederick mentioned the push down of the cap. Both Pauls have pushed those "toxins" down into the wine hundreds of times and didn't even know it. Those toxins are always there. Even SO2 doesn't kill them. SO2 puts them in suspended animation until the SO2 levels drop. Bleach would kill them but then there really would be "toxins" in the wine. How many "toxins" have people drunk in this world when the SO2 levels of the wine they are drinking become low?? Just because you can't see them doesn't mean they are not there and it's ironic that the cap keeps getting pushed into the fermenting must to kill them. Maybe the fermentation does do something. Imagine that.

It depends on how advanced the mold is. If you catch it fairly quickly and it's only on top, you can rack the must out from under the mold (leaving behind a couple of inches to make sure you don't carry the mold into the new fermenter) and pitch yeast. If it's been growing for a while toss it, as the mold produces toxins that will have spread throughout the must and cannot be easily removed. -- I just forgot my whole philosophy of life!!! |

I forgot to mention the crush. Grapes are never washed before the
crush. Do you realize how much bird shit is on those grapes? How much echoli bacteria is in the musts before the fermentaion? How do the two Pauls deal with that? Oh, that's right, they pitch the yeast. Bob On Oct 26, 9:08 am, wrote: The two Paul's in this thread would make good Republican Presidential candidates.

Surface mold grows on the surface film for a reason. That is where
it finds the "living conditions" it requires. Relatively stable, relatively dry, and abundant oxygen. Had you stirred the juice/must 2 or 3 times a day, you would have disrupted these "living conditions" long enough for the yeast to get started. Even when the yeast gets going, you need to keep stiring once or twice a day so long as there remains any solids or foam on the surface that might dry out enough to let the mold get reestablished. When you see advice about things like stiring, pump over, punch down, etc., take heed. There are always reasons for the things we do.

Cents everyone has 2 pennies of advice, here is mine. :*) (yes, I know I
spelled it wrong) Adding yeast would have helped. Possibly adding sugar, but it depends on the S.G. With yeast so inexpensive, I would never let fruit or grapes ferment on their own, though I realize that's the way they did it 2000 years ago, they also didn't have $.99 yeast packets available. Some of the best grapes and fruit for making wine is over ripe, meaning all kinds of mold and stuff is happening to them. I also agree with several comments above about catching it quickly (not 4 months later) and racking out the top mold. IMHO. My apple cider wine was made two years ago and will be in the bottle another year before it's close to ready. But it is promising! I do appreciate learning from everyone's 2 cents - I got a pocket full of change now a-days.

If you want to drink bad smelling "wine", be my

You can never have enough info. If she makes a decision based on the
limited info presented here, I will guarantee it will be an ill- informed decision. Bob On Oct 30, 11:56 am, "Paul E. Lehmann" wrote: wrote: If you want to drink bad smelling "wine", be my guest.

Sadly there seems to be a degree of derision on this thread as well as
the useful opinions and information. The information is useful, the derision is not. I am not sure myself as to whether all byproducts of bacterial spoilage are neutralised when the alcohol levels rise high enough to kill the infection. I couldn't find much online about it and I don't know whether many of these byproducts are poisonous either. Information and opinion given by long-term winemakers on this thread is interesting though and does help to form a strategy as well as opinion. I'd be interesting to hear more on this subject. Perhaps the lack of testimony from people quoting a negative experience shows that there is rarely a problem with procedures suggested. Perhaps it just shows that they haven't read this thread yet.
