What Is Kosher Wine?

When it comes to wine, there’s more than just taste, aroma, and pairing to consider—especially for those who follow Jewish dietary laws.

Kosher wine holds a special place in Jewish tradition and is deeply intertwined with religious customs and ceremonies.

But what exactly makes wine “kosher,” and how does it differ from non-kosher wine? Let’s explore.

Understanding Kosher Wine

The word “kosher” stems from Jewish dietary law, known as kashrut, and it refers to food and drink that complies with these strict regulations.

When it comes to wine, being kosher is not just about the ingredients used but also about the entire process of production—from grape harvesting to bottling.

For wine to be considered kosher, it must adhere to specific religious guidelines, and certain rules must be followed during its creation.

Only observant Jews who strictly follow Jewish law are allowed to be involved in the production and handling process, including fermenting and bottling the wine.

Furthermore, no animal products like gelatin or casein (used in some non-kosher wines as clarifying agents) are permitted in kosher wine production.

What Makes Wine Kosher?

Wine plays a sacred role in many Jewish rituals—from Sabbath meals to Passover Seders, weddings, and other religious ceremonies. Because of this sanctity, the standards for kosher wine are especially strict.

To qualify as kosher, wine must meet several specific requirements:

1. Only Sabbath-Observant Jews Can Handle the Wine

From the time the grapes are crushed until the wine is sealed in the bottle, only observant Jews (who keep the Sabbath and kosher laws) are allowed to touch the wine and equipment. If anyone else handles it, the wine is no longer kosher.

2. Kosher Ingredients Only

Every element, from the yeast used in fermentation to any fining agents, must be kosher. Many winemakers use fining agents like gelatin or casein (milk protein), but for kosher wine, these must come from kosher-certified sources.

3. Dedicated or Koshered Equipment

All equipment, including tanks, barrels, and bottling lines, must be kosher or properly cleaned and sterilized under rabbinical supervision.

Types of Kosher Wine

Kosher wine isn’t a separate grape variety or style—it’s a category based on how the wine is made. You’ll find all the same types of wine in kosher versions, including:

Red wines like Merlot, Cabernet Sauvignon, and Shiraz
White wines like Chardonnay and Sauvignon Blanc
Rosé and Sparkling wines
Dessert and fortified wines (such as kosher Port or Muscat)

Kosher wines are produced in many wine-growing regions, including:

Israel – with well-known vineyards in the Galilee and Golan Heights
United States – especially in California’s Napa Valley
France, Italy, Spain, and Argentina

Popular kosher wine brands include Barkan, Yarden, Covenant, Herzog, and Tishbi.

The Role of Mevushal (Boiled) Wine

One unique category within kosher wine is Mevushal wine. Mevushal, meaning “cooked” in Hebrew, refers to wine that has been flash pasteurized—heated quickly to a high temperature and then cooled.

Why is this done?

In Jewish law, if a non-Jew handles kosher wine, it can lose its kosher status. But once wine is mevushal, it can be handled and served by anyone—even those who are not Jewish or not observant—and it remains kosher.

This is especially useful at weddings, restaurants, and large events where non-Jewish waitstaff or guests may be pouring or serving the wine.

Does it affect the taste?

Yes, it can. High-end wineries use advanced flash pasteurization to minimize changes, but wine connoisseurs sometimes prefer non-mevushal kosher wines for their more refined and unaltered taste profiles.

How to Identify Kosher Wine

When shopping for kosher wine, here’s what to look for on the label:

A kosher certification symbol (such as OU, OK, Star-K, Kof-K)
The word “Kosher” or “Kosher for Passover”
The term “Mevushal” (if applicable)

Be cautious—just because a wine comes from Israel or has Hebrew on the label doesn’t necessarily mean it’s kosher. Always check for certification.

Kosher Wine vs. Non-Kosher Wine

At first glance, kosher and non-kosher wines may seem identical, especially since they can both be made from the same types of grapes and in the same regions. However, there are distinct differences that set kosher wine apart:

Religious Supervision: A key factor is that kosher wine is overseen by a rabbi to ensure it adheres to Jewish law.
Production Rules: Kosher wine must be handled only by observant Jews during production, and no non-kosher ingredients are allowed.
Equipment Use: The equipment used in making kosher wine must be cleaned according to religious standards and cannot have been used to produce non-kosher wine without being properly koshered.

Kosher for Passover vs. Regular Kosher Wine

Not all kosher wines are automatically suitable for Passover, when the restrictions are even stricter. During this holiday:

Wine must be free from chametz (leavened grain products) and kitniyot (certain legumes, depending on tradition)
Even the yeast must be Passover-approved

Look for the label “Kosher for Passover” to be sure.

Is Kosher Wine Only for Jews?

Absolutely not. Many people choose kosher wine for a variety of reasons:

Purity and strict quality control
Vegetarian- or vegan-friendly options
Curiosity about different wine styles
Ethical and clean winemaking practices

Kosher wines can appeal to anyone looking for a high-quality, trustworthy product—regardless of religious background.
