Kosher wine

Kosher wine is a science topic covered in the lgStudy science library. This page brings together a partial reference excerpt, illustrations, worked examples, real-world applications and a short study plan, so you can understand Kosher wine rather than just read about it. In short: Kosher wine (Hebrew: יין כשר, romanized: yáyin kashér) is wine that is produced in accordance with halakha, and more specifically kashrut, such that Jews will be permitted to pronounce blessings over and drink it. Wine has great significance in Judaism, since wine is used in several Jewish ceremonies, especially those of Kiddush.

Key takeaways

  • Kosher wine belongs to science; place it in that map before memorising details.
  • Learn the definition first, then one example that makes the definition concrete.
  • Connect Kosher wine to a quantity you can measure, compute or draw — that is where exam questions come from.
  • Reproduce the core statement of Kosher wine from memory before moving on to harder problems.

Reference excerpt

Kosher wine (Hebrew: יין כשר, romanized: yáyin kashér) is wine that is produced in accordance with halakha, and more specifically kashrut, such that Jews will be permitted to pronounce blessings over and drink it. Wine has great significance in Judaism, since wine is used in several Jewish ceremonies, especially those of Kiddush. To be considered kosher, Sabbath-observant Jews must supervise the entire winemaking process and handle much of it in person, from the time the grapes are loaded into the crusher until the finished wine product is bottled and sealed. Additionally, any ingredients used, including finings, must be kosher. Wine that is described as "kosher for Passover" must have been kept free from contact with leavened or fermented grain products, a category that includes many industrial additives and agents. When kosher wine is produced, marketed, and sold commercially, it would normally have a hechsher (kosher certification mark) issued by a kosher certification agency, or by an authoritative rabbi who is respected and known to be learned in Jewish law, or by the Kashruth Committee working under a beth din (rabbinical court of Judaism). In recent times, there has been an increased demand for kosher wines, and a number of wine-producing countries now produce a wide variety of sophisticated kosher wines under strict rabbinical supervision, particularly in Israel, the United States, France, Germany, Italy, South Africa, Chile, and Australia. Two of the world's largest producers and importers of kosher wines—Kedem and Manischewitz—are both based in the American Northeast.

History

The use of wine has a long history in Judaism, dating back to biblical times. Archeological evidence shows that wine was produced throughout ancient Israel. The traditional and religious use of wine continued within the Jewish diaspora community. In the United States, kosher wines came to be associated with sweet Concord wines produced by wineries founded by Jewish immigrants to New York. Beginning in the 1980s, a trend towards producing dry, premium-quality kosher wines began with the revival of the Israeli wine industry. Today kosher wine is produced not only in Israel but throughout the world, including premium wine areas like Napa Valley and the Saint-Émilion region of Bordeaux.

Role of wine in Jewish holidays and rituals It has been one of history's cruel ironies that the blood libel---accusations against Jews using the blood of murdered non-Jewish children for the making of wine and matzot---became the false pretext for numerous pogroms. And due to the danger, those who live in a place where blood libels occur are halachically exempted from using [kosher] red wine, lest it be seized as "evidence" against them. Almost all Jewish holidays, especially the Passover Seder where all present drink four cups of wine, on Purim for the festive meal, and on the Shabbat require obligatory blessings (Kiddush) over filled cups of kosher wine that are then drunk. Grape juice is also suitable on these occasions. If no wine or grape juice is present on Shabbat, the blessing over challah suffices for kiddush on Friday night; for Kiddush on Shabbat morning as well as Havdalah, if there is no wine one would use "Chamar ha-medinah", literally the "drink of the country".

At Jewish marriages, circumcisions, and at redemptions of first-born ceremonies, the obligatory blessing of Borei Pri HaGafen ("Blessed are you O Lord, Who created the fruit of the vine") is almost always recited over kosher wine (or grape juice). According to the teachings of the Midrash, the forbidden fruit that Eve ate and which she gave to Adam was the grape from which wine is derived, though others contest this and say that it was in fact a fig. The capacity of wine to cause drunkenness with its consequent loosening of inhibitions is described by the ancient rabbis in Hebrew as nichnas yayin, yatza sod ("wine enters, [and one's personal] secret[s] exit"), similar to the Latin "in vino veritas". Another similarly evocative expression relating to wine is: Ein Simcha Ela BeBasar Veyayin—"There is no joy except through meat and wine".)

Requirements for being kosher

Because of wine's special role in many non-Jewish religions, the kashrut laws specify that wine cannot be considered kosher if it might have been used for idolatry. These laws include prohibitions on Yayin Nesekh (יין נסך – "poured wine"), wine that has been poured to an idol, and Stam Yeynam (סתם יֵינָם), wine that has been touched by someone who believes in idolatry or produced by non-Jews. When kosher wine is yayin mevushal (יין מבושל – "cooked" or "boiled"), it becomes unfit for idolatrous use and will keep the status of kosher wine even if subsequently touched by an idolater. While none of the ingredients that make up wine (alcohol, sugars, acids and phenols) is considered non-kosher, the kashrut laws involving wine are concerned more with who handles the wine and what they use to make it. For wine to be considered kosher, only Sabbath-observant Jews may handle it, from the first time in the process when a liquid portion is separated from solid waste, until the wine is pasteurized or bottles are sealed or even sold from kosher supermarkets. Wine that is described as "kosher for Passover" must have been kept free from contact with chametz and kitnios. This would include grain, bread, and dough as well as legumes and corn derivatives.

Worked examples

Example 1 — a first encounter with Kosher wine

Start with the simplest possible case. Write down what Kosher wine claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In science, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to Kosher wine before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about Kosher wine ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of Kosher wine

In research
Kosher wine appears in science research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry
Engineering practice reuses Kosher wine in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom
Kosher wine is common in secondary-school and first-year university syllabi. It links to neighbouring topics Jewish ceremonial food and drink, Judaism and alcohol, Kosher wine, so understanding it makes those chapters shorter.
In everyday life
Look for Kosher wine outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.

Why does Kosher wine matter?

Because it connects several science ideas at once: it gives you a definition you can apply, a quantity you can calculate, and a way to check whether a result is plausible.

How should I study Kosher wine?

Read the excerpt, restate it from memory, then work through the examples and applications listed on this page. The five-step study plan above takes about twenty minutes.
