Wine and Spirits Under Halakhic Investing: Diageo, Constellation Brands

Wine gets a strange treatment in Jewish law. It's holy enough to bless on Shabbat and at every Jewish wedding, yet it carries a unique prohibition that doesn't apply to any other food: wine touched or handled by a non-Jew becomes forbidden. So how does that interact with owning stock in a giant wine company like Constellation Brands?

Let's work it out.

Two Categories: Yayin Nesech and Stam Yeinam

The Talmud distinguishes between two kinds of non-Jewish wine.

Yayin nesech is wine actually used in idol worship. The Torah forbids it explicitly in Deuteronomy 32:38, where idols are mocked with the line, "Who ate the fat of their sacrifices and drank the wine of their drink offering." The rabbis categorized yayin nesech under the strictest prohibition: a Jew cannot drink it, derive benefit from it, or own it. It's issur hana'ah.

Stam yeinam is regular wine made or touched by non-Jews but not specifically used for idol worship. The Talmud in Avodah Zarah 29b-31a extends the prohibition to stam yeinam as well, but at a lower level. Stam yeinam is forbidden to drink but permitted for benefit in some contexts. The debate between Rishonim (medieval authorities) about the exact scope of benefit permission is extensive.

The Shulchan Arukh Yoreh Deah 123 rules that stam yeinam is forbidden to drink but permitted for benefit outside of idol worship contexts. This is a critical ruling for modern investing.

What Makes Wine Kosher

Kosher wine has to be produced entirely by Sabbath-observant Jews from start to finish. The grapes can be handled by non-Jews, but once they're crushed and the juice becomes wine (halakhically, this happens when fermentation begins), only Jewish hands can touch it.

This creates a small industry of mashgichim (kosher supervisors) who watch wine production and handle every step of the process. Kosher wine producers like Manischewitz, Bartenura, Carmel, Yarden (from Israel), Herzog, Royal Wine, and Baron Herzog all operate under strict OU, Kof-K, or OK supervision.

Mevushal wine is a special category: wine that has been heated (traditionally to boiling, now usually flash-pasteurized) to a specific temperature. Once mevushal, the wine can be handled by non-Jews without becoming forbidden. This is why mevushal wine is common at weddings and events where non-Jewish waiters might pour it.

None of the major publicly traded wine producers are fully kosher. Constellation, Diageo, Pernod Ricard, Treasury Wine Estates , none of them operate under Jewish supervision.

Can You Own Non-Kosher Wine Stocks?

Here's where stam yeinam vs yayin nesech matters for investing. Since the mainstream ruling treats stam yeinam as forbidden to drink but permitted to benefit from, owning shares in a non-kosher wine company falls into the benefit category, not the drinking category.

Rav Moshe Feinstein (Igrot Moshe Yoreh Deah 1:72 and 2:57) addresses this question indirectly in his rulings on passive ownership of non-kosher food businesses. The corporate-veil logic applies the same way to wine companies: shareholders are not personally producing, handling, or drinking the wine. They own corporate equity and collect dividends from corporate profit.

Under Feinstein's ruling, owning Constellation Brands (STZ), Diageo (DEO), Brown-Forman (BF.B), or similar is permitted even though the wine they produce is stam yeinam.

The Chazon Ish, again, takes a stricter view. Some Chasidic authorities go further and prohibit investment in any wine company on the grounds that wine is a uniquely sensitive substance in Jewish law and investors shouldn't benefit from its non-kosher production even through passive ownership.

Revenue Mix Matters

Wine companies aren't all alike. Let me walk through the big publicly traded names.

Constellation Brands (STZ): Total revenue of roughly $10.2 billion in fiscal 2024. The business mix is heavily tilted toward beer, not wine. Modelo, Corona, Pacifico, and Victoria are the crown jewels , beer revenue is about $8.4 billion (82% of total). Wine and spirits together are only about $1.8 billion (18%). If you're thinking "Constellation = wine," you're thinking about the company that existed 10 years ago. Today STZ is effectively a beer company with a wine sleeve.

Diageo (DEO): Total revenue of roughly $20 billion. Diageo is the world's largest spirits company, owning Johnnie Walker, Smirnoff, Tanqueray, Crown Royal, Guinness, Baileys, Captain Morgan, Don Julio, and many more. Wine is a relatively small part of the portfolio. Spirits are about 80% of revenue, beer (mostly Guinness) is about 15%, wine is under 5%.

Brown-Forman (BF.B): Total revenue of roughly $4 billion. Famous for Jack Daniel's, which is about 50% of the business. Other spirits (Woodford Reserve, Gentleman Jack, Finlandia) make up most of the rest. Wine is essentially nothing.

Pernod Ricard (RI.PA, also PDRDY ADR): Total revenue of roughly €12 billion. Owns Absolut, Chivas Regal, Jameson, Beefeater, Martell, Perrier-Jouet, and more. Spirits are about 90% of revenue, champagne and wine about 10%.

Treasury Wine Estates (TWE.AX, or TSRYY ADR): This is an actual pure-play wine company. Australian-listed, owns Penfolds, Beringer, Sterling, Beaulieu Vineyard, and many others. Total revenue around $3 billion. Wine is essentially 100% of the business.

The Beer Question

Beer has no equivalent to yayin nesech. It's not governed by the same wine-specific prohibitions. Beer is halakhically similar to any other food: if it's kosher, you can drink it; if it's not, you can't. But for passive investment, the corporate-veil logic applies with very little controversy.

Modern beer is generally considered kosher by default as long as it doesn't contain problematic additives. Most mass-market beers (Budweiser, Coors, Miller, Modelo, Corona, Guinness) have kosher certification for standard product lines. This means Constellation Brands, whose revenue is 82% beer, is actually producing primarily kosher-certified products.

The implication: if your halakhic screen is set to exclude wine companies but your screen misses that STZ is mostly a beer company, you'd wrongly exclude it. A smarter screen looks at revenue breakdown rather than company name or category label.

Screening Thresholds in Practice

If you apply a 5% threshold for non-kosher wine revenue, you get:
- STZ: passes easily (wine is under 18% of revenue, mevushal certification would shrink this further)
- DEO: passes (wine under 5%)
- BF.B: passes (essentially no wine)
- Pernod Ricard: borderline, fails at 5% strict
- Treasury Wine Estates: fails badly (100% wine)

If you apply a 25% threshold:
- All of the above pass except Treasury Wine Estates

If you screen out all companies that produce any stam yeinam wine at all:
- Only pure-play wine companies get hit, and those are rare in US public markets. Treasury Wine is the main name.

The Alcohol Question Separate From Wine

Some halakhic investors extend screening to cover all alcohol, not just wine. This is more of a pious or community-standard choice than a strict legal requirement. The Torah never prohibited alcohol consumption; the laws of the nazir (Numbers 6:1-21) created a voluntary vow to abstain from wine and wine-derived products for a period, but nezirut was always optional and it was explicitly temporary.

The Talmud in Berachot 40a and Bava Batra 12b speaks favorably about wine's ability to "gladden the heart of man" (quoting Psalms 104:15). Kiddush, Havdalah, weddings, bris, and Passover all require wine. So wine isn't intrinsically problematic in Jewish law, which is why screening out all wine and alcohol companies isn't the mainstream halakhic approach.

If you nevertheless want a full alcohol exclusion for personal or community reasons, you'd exclude:
- STZ (despite the beer-heavy mix)
- DEO
- BF.B
- Pernod Ricard
- Treasury Wine Estates
- Boston Beer (SAM)
- Molson Coors (TAP)
- Anheuser-Busch InBev (BUD)

Thinking About Passover

One edge case worth mentioning: on Passover, the prohibition on chametz extends beyond wine to cover anything containing leavened grain products. Beer is specifically problematic because it's made from fermented grain (typically barley), and most beer has chametz status during Pesach.

Some strict halakhic investors sell their shares of beer companies before Passover each year, using a mechirat chametz procedure to transfer ownership to a non-Jew for the duration of the holiday. This is the same legal structure used to sell household chametz before Pesach.

Most modern Orthodox financial advisors don't require this for passive stock ownership because the shareholder doesn't physically possess the beer. The Star-K and other kosher certification agencies have issued opinions that passive stock ownership of beer or whiskey companies doesn't trigger the chametz prohibition in the way that direct ownership of physical inventory would.

If you want to be stringent, some Orthodox brokerages offer automatic pre-Passover chametz sale for your holdings. Ask your financial advisor if they work with a rabbinic authority who provides this service.

Building a Wine-Aware Portfolio

Practical approach for someone building a halakhic portfolio in 2026:

1. Apply a 5% or 10% threshold for non-kosher wine revenue. This cleanly excludes Treasury Wine Estates while permitting Constellation, Diageo, and Brown-Forman.
2. Treat beer and spirits as separate categories. Unless you have a personal reason to exclude all alcohol, beer and spirits companies can be held under the corporate-veil logic.
3. If you're keeping chametz-strictness on Passover, arrange a mechirat chametz for your brewing-company stocks with a competent rabbi before each Pesach.
4. For portfolio exposure to kosher-friendly food and beverages without the wine question, look at Coca-Cola (KO), PepsiCo (PEP), Monster Beverage (MNST), and Keurig Dr Pepper (KDP). All four have substantial kosher-certified product lines and no wine exposure.

Bottom Line

Wine is a unique category in Jewish law, but the uniqueness mostly shows up in how it's produced and consumed, not in how it's owned as a financial asset. The mainstream halakhic ruling, rooted in Rav Moshe Feinstein's work and the Shulchan Arukh's distinction between yayin nesech and stam yeinam, permits passive investment in non-kosher wine producers under the corporate-veil framework.

A thoughtful halakhic portfolio can hold Constellation, Diageo, and similar names without controversy. Strict investors can exclude them on pious grounds, and pure-play wine companies like Treasury Wine Estates can reasonably be excluded under even lenient thresholds. What matters more than any single name is having a consistent framework you've thought through and can defend to yourself.
