Why is it permitted to drink wine on Passover when it is fermented with yeast?

Before refrigeration there would be no question on this subject. Passover is in the spring there’s no way to have fresh grape juice in spring. Grapes are harvested in the fall, at passover time your gonna have one of two things alcoholic wine or vinegar. There’s no other way about it. Reply

Another interesting spin on justifying ourselves before God. Good luck with that! Reply

But doesn't the Torah say, "No leaven shall be seen of yours, and no leavening shall be seen of yours throughout all of your borders."

--speaking of the leavening agents themselves? Am I missing something here? Reply

Is this still a working site? If so I would like to know if fermented vegetables like krout is kosher for Passover? I made it with salt water and probiotic capsules to jump start fermentation. Thank you!! Lois M. Reply

Yeast or leavened dough was that which had to be taken from the house, not just simply things that leaven, which would include the air. It was bread specific. Besides wine is generally fermented, which means it has stopped fermenting, which makes it wine. Bread itself didn't have to be removed, but rather dough that had the ability to ferment in it. As per who know leavened dough is kept from becoming bread and is used to infect other dough, which is made into bread. Each time bread is made dough from the bread to be made is kept apart as leavening for the future bread making. Reply

"Of the hundreds of species of yeast, the Passover prohibition only applies to yeast which is a product of one of the following five grains." As I understand it yeast is not the product of the grains, but rather the grains in their risen state are the product of the yeast. The yeast are microbial organisms that have contaminated the grain. These are the same organisms that cause wine sugars to ferment and grains to swell. So, if the prohibition is against leaven, then wine should be included. But, if the prohibition is against unleavened "bread" then act accordingly. However, I believe the real message is to show us how difficult or impossible it is to remain uncontaminated from the influence of sin. Reply

We do not focus on the bread If only we would focus on the bread. Instead we are distracted by hundreds of other foods that are not even mentioned in the Torah--beans, rice, seeds, corn syrup, etc. This is the key quote: "Then Moses told the people, "Remember this day on which you came out of Egypt, from the house of bondage, because the L-rd brought you out from this place with a strong show of force. Moreover, nothing leavened is to be eaten." Nothing leavened. G-od was very clear about what He wanted us to eat and not eat. But some men decided that they knew better and "reinterpreted" G-od's words to fit with their own ideals, and suddenly we can eat Passover cakes and rolls leavened with eggs and baking soda but we can't eat green beans or peas.

Non-grain yeast Bread risen with non-grain yeast is still chametz because it is bread made from grain.
The Pesach story was about bread rising which shows ego, bread that has not risen shows humility. In this instance, in the story of Pesach it was about the bread, so that is how we commemorate it. Not using any food that rises is an interesting point, but I think it is the bread we are focusing on. Reply

Non-Grain Yeast is Permitted? Sorry, but that makes zero sense. If non-grain yeast is permitted, then bread risen with non-grain yeast would also be permitted.

Forget the yeast--the emphasis should be on avoiding risen foods. Period. Nothing risen should be permitted, and it shouldn't matter if the food has risen due to yeast, eggs or baking soda. The entire point of the Exodus story is that there was not enough time to allow for the bread to rise before baking it due to the need to flee Egypt as soon as possible. That bread had yeast in it, but it was unrisen bread. So avoiding risen foods would be much more in keeping with the spirit of Passover than simply avoiding yeast. Reply

Nothing to do with yeast It has nothing to with yeast, it has to do with grain, if the yeast comes from grain then it is chametz, if the yeast comes from the grape then it is not. Chametz is about grain not yeast. Reply

drinking Wine Why do people take issue when someone drinks a glass or two of wine during the Passover Reply

Yeast is in the air naturally. Who determined that the yeast that ferments grape juice is not chametz? I do not see that in torah. What Torah verse is this ruling from? Reply

Actually, the answer to the original question is this all yeast is burned up during the fermentation process. The dregs fall to the bottom of the vat and are removed. There is no yeast in wine after it has been fermented. The rabbi is also wrong. No yeast is to be found in the house on Passover. Reply

Yeast is not a product of any grain. Yeasts are eukaryotic microorganisms that can live in a variety of environments, mostly as a commensal parasites. Reply

How is yeast a "product" of something else? It's the same yeast involved for beer fermentation as in wine so why is beer not kosher and wine is? Makes no sense. Reply

Things we didn't know in the past. Eh... there is no yeast difference. You mean fermentation products. The yeast in bread is still yeast as is the yeast in wine. So fermented grapes are okay, but fermented bread not and also no beer because these are both grain products.

Basically the people that made up the rules didn't know how yeast works and didn't even know microbial life was the reason things fermented. That's why they excluded bread and beer, because they are made from fermented grains, but ignored fermented grapes, despite the same yeast being in the product. (I think it's even the same species)

You're free to believe whatever you want to believe about the validity of your holy books, but understand there's a big (I say 100%) human element to it and this means that often there's not a good reason for why things are done other than tradition. Reply

This is ridiculous! Ashkenazi jews will out law rice beans and salt yet not wine? Wine is hametz regardless how you look at it even more so then rice. Alcohol is a by product of yeast! Reply

Yeast with tendrils? This is hilarious. Yeast is a fungus, a unicellular organism. As others have pointed out, yeast has nothing to do with this conversation. If so, we wouldn't be able to take showers or breathe the air; yeast is everywhere! Reply
