Update From the Star-K Regarding Beer Distributor


It has come to our attention that much of the beer sold in New York and surrounding counties is distributed by a Jewish owned company, creating a potential Chometz She’avar Alav haPesach issue for our communities. The following is a brief explanation of the issue.

What exactly is Chometz?

The Torah[1] forbids eating any chometz – leavened grain products during Pesach. Simply defined, leavening is dough or batter that has increased in volume either through yeasts or chemical means. The process of how this happens is the following.

A chemical leaven such as sodium bicarbonate (baking soda) react with compounds naturally present in the dough to produce carbon dioxide. The carbon dioxide (CO2) released from this reaction becomes trapped inside the dough, thereby causing the dough to expand – and rise.

Another way to cause dough to rise is through a process called fermentation. Yeast, a fungus naturally present in grains (or commonly added to assist this process to occur more quickly), becomes activated when it comes into contact with warm water. This activated yeast converts sugars that are naturally present in the dough into alcohol and CO2[2]. This CO2 is what causes the bread to rise. If the dough is allowed to ferment for a long time, it will become concentrated with enzymes and, since much of the sugars were broken down, will taste sour, referred to in the Torah as se’or – sourdough.

The only grains that will leaven are grains that contain starch and have the requisite components to react with yeast thereby causing CO2 to be released. This process is only found in the five grains, wheat, oats, barley, rye and spelt. Other “grains” (e.g. rice, millet, corn, quinoa etc.) will not rise or ferment naturally when water is added; they will begin to decompose and emit a foul odor[3], and, as such, are not chometz[4].

With this understanding, we can now look at the beer production process.

The Beer Production Process:

The basic steps in production of beer are malting, mashing, lautering, boiling, and fermentation. Here is a quick review of the process.

Malting is when barley is mixed with water and allowed to soak until the barley sprouts, thereby activating the natural enzymes in the grain. These enzymes convert starches in the barley into sugar. Next comes mashing, when hot water is added to the malt to further allow all the starches to turn into sugar. This is followed by lautering, where the liquid is drained off from the barley solids. This liquid is known as wart. If the process would stop here, we would have a drink that is quite sweet, so the wart is put into a tank to boil together with a flower called hops which contribute a bitter taste. Sometimes, a clarifying agent is added to the tank to help remove any undesirable protein solids that may be left over.

The final stage is fermentation. The boiled liquid is cooled and placed in a fermentation tank; yeast is added and the sugars are converted into alcohol, releasing CO2 along the way and…you have beer!

If you followed this process, you can understand quite well how the fermentation of barley into beer is exactly the process that the Torah calls chometz. This makes beer unquestionably chometz gamur[5].

Chometz She’avar Alav haPesach

Besides the prohibition of consuming chometz, a Jew is also not even allowed to own chometz on Pesach and one who did violates the prohibition of ba’al yiraeh uba’al yimatzeh[6]However, that’s as far as it goes midiOraysoChazal, however, enacted a prohibition of chometz she’avar alav haPesach as a knas (punishment) for violating ba’al yira’eh uba’al yimatzeh.[7] They felt that if chometz she’avar lav haPesach was allowed, people wouldn’t get rid of all their chometz. They instituted that chometz she’avar alav haPesach remains prohibited – forever and on everyone, not just for the violator.

Therefore, beer that was owned by a Jew during Pesach remains prohibited forever[8].

New York Beer Distribution

In the state of New York, beer distribution companies have exclusive rights to the brands that they distribute in areas that they are licensed to sell. One of the largest distributors in New York is  known to be Jewish owned. Longstanding Star-K policy has always been not to rely on a mechira in these circumstances. Therefore, while it has become known that a mechira was arranged with the distributor, Star-K certified establishments and caterers should only use items that are free from any concern. Individuals should consult their own Rov. Please check our website after May 15th for an update on how long this issue will be in effect.

The STAR-K beer alert lists all the affected beers as well as a partial listing of popular beers that we have been able to determine present no issue of chometz she’avar alav haPesach.


Q: Why didn’t we know about this until now?

A: We only became aware of this issue in the last year.

Q: How can you know when the beer being distributed is from after Pesach?

A: We are in contact with people in the industry to figure out when the stock of beer will have turned-over. Also, beers have the date code on the bottle/can, which will indicate the production day.

Q: Why does it only affect some brands?

A: It depends where the distributers are licensed to sell.


[1] Shmos 12:15

[2] When the dough is baked, the alcohol evaporates.

[3] Reffered to in halacha as sirchon

[4] See Shulchan Aruch 453:1. Chazal still prohibited some of these “other” grains, known as kitniyos.

[5] The process of converting starches to sugars and then to alcohol which releases CO2 along the way (i.e. fermentation) precisely defines the leavening process. In dough, the CO2 is trapped and causes the dough to rise. With beer, it creates the carbonation, a defining characteristic of beer. See Shulchan Aruch O”C 442:5 and M”B there #24.

[6] Shmos 12:19, Devorim 16:4

[7] See Pesachim 29a.

[8] The Shaarei Teshuva in 442:3 brings a Noda B’Yehuda that talks about whiskey, which is, simply put, distilled beer. He entertains the idea that maybe whiskey is not chometz gamur and only considered zaiya b’alma/extracted juice. However, in the end, he does not conclude this way. Also see M”B 442:4. Either way, beer, which is not distilled, would NOT have this possible heter and is – according to EVERYONE – chometz gamur.


  1. The OK has put out a letter stating with no uncertainty that they sold all of the chametz for this distributor kehalacha.

    Why is the Star K making these claims and causing such confusion and issues?

  2. Ok, now I understand the Issur but what about the Shtar Mechira for those that do sell Chometz Gomur? Can we rely on that?

  3. Still doesn’t explain why the Star-K did not alert the general public, not just its certified establishments!
    Why did we have to first hear it from someone who “leaked “it?

    Something smells rotten!

  4. The Star-k (and OU) are skeptical about a lot of these multi-million dollar “mechiras” which look more like a show than a sale. Where the Jew still does business on Pesach receiving all profits from the business, even though it officially belongs to the non-Jew.

    That is why the Star-K book says not to purchase chometz from Target, Stop & Shop etc.. Their distributor is a Yid, even though a mechira is done. The mechira is questionable and Star-K (and OU) are not comfortable with it.

    There is nothing new here. It’s consistent with the Star-K policy and what was already printed in their book.

  5. The company is not shomer Torah uMitzvos and they continue to sell their products on Pesach. That makes the whole sale smell rotten.

  6. There are people who do not sell real chometz and hold that the sale is invalid for such items as it is only a haroma. yet they can purchase items from someone who followed their rov/posek/hechsher and sold the chometz, we would not put on the knas of chemetz sheover pesach if the person followed their posek. the fact that the star k does not agree to the mechanics of the ok’s sale does not remove the fact that there are poskim that allow such a sale. there were rabonim in that allowed a sale in a manufacturing plant that was making chometz on pesach by i think rabbi tietz z”l and as such there is no knas on someone who followed their rov. this feels like it has more to do with political posturing then it does halachah.
    The star K allows one to adjust the temperature on their oven on yom tov, i heard from a choshiva rov and posek that while he holds that it is asur to adjust the ovens, we do not say the food cooked in an oven after it was adjusted is asur because of the knas, because the person was following their rov (the star K) does this meen the star k hold i can not eat food cooked in a star k oven?

  7. Dave is 100% correct!
    If someone follows a psak of a Rov then EVEN IF THE ROV WAS WRONG there is NO KNAS and there is no chametz she’avar olov haPesach. It is 100% mutar to drink the beer even if you don’t hold of the mechira. Chazal did NOT make a knas in such a case.
    (BTW that’s why even people who don’t sell chametz gamur are allowed to eat at a kiddush after Pesach and don’t have to ask if any of the chametz was “sold” chametz.)
