Certification is necessary for a number of reasons. It is important to realize that all whiskey produced in the United States is taxed by the government. The amount of tax levied is based on the amount of alcohol in the bottle. An eighty-proof bottle of whiskey, for example, will be taxed less than a one hundred-proof bottle. (Proof equals ½ percent. One hundred proof is 50 percent alcohol.) Currently, distilled spirits are the most heavily taxed consumer products in the United States. Indeed, federal, state and local governments receive more than $18 billion per year in tax revenue from the beverage alcohol industry. In fact, one manufacturer told me that he pays more in taxes than he pays for the bottle, the material and the processing combined! In light of the high taxes levied on these beverages, manufacturers are constantly looking for legal loopholes that would enable them to elevate the alcohol content without incurring additional tax.

To kosher consumers, the obvious question is, “What are blenders made of?” There are thousands of flavor chemicals, and any one of them can be used in a blender, as long as it has been deemed “GRAS,” that is, Generally Regarded As Safe, by both the government and the flavor industry. Of course, some of these ingredients are not kosher. (Common non-kosher ingredients used in blenders are listed later in this article.)

But even if we ascertain that the blender in the whiskey is kosher, there may still be a problem: Since wine is taxed at a much lower rate than whiskey, oftentimes whiskey not only contains blenders, it contains wine. Wine raises the alcohol content without incurring the tax reserved for liquor. All of these issues present Kashrut concerns. There are those in the kosher certification industry who maintain that blenders do not pose any kashrut problems. They base their belief on the following faulty reasoning: Since a blender is not drinkable at 14 percent, it is nifsal meachilat kelev—not suitable for a dog to consume—and therefore blended whiskey need not have certification.

This is not the position taken by the Orthodox Union. The term nifsal meachilat kelev applies to food that is inherently bad at any concentration. A dog, for instance, would probably not eat a few ounces of straight garlic powder, but that does not render garlic powder nifsal meachilat kelev. This is because as a spice, garlic powder is tasty. The Halachic principle of nifsal meachilat kelev applies to the inherent quality of the food, not how the food tastes in one concentration or another.

The position of the Orthodox Union is that blenders fall into the category of avidah leta’ama since they too impart a strong flavor. Thus, blenders cannot be batul and can therefore pose significant kashrut problems. Below are examples of non-kosher ingredients found in blenders:

1. Isoamyl alcohol—possibly derived from wine.

2. Glycerine—a percentage of which is derived from animal fat.

3. Fatty Acids and their derivatives, i.e., esters of fatty acids—some are animal derived. Others are produced on machinery used for products containing animal fat.

Obviously, alcoholic extracts require kosher certification since they can be made on non-kosher equipment

5. Cream—sometimes derived from non-kosher whey.

6. Butter acids and butter esters— sometimes derived from non-kosher whey.

Following is a brief explanation of various liquors and the position the Orthodox Union takes regarding their kosher status.

VODKA
In the United States, vodka is made by distilling grain-derived crude alcohol, which results in an almost pure alcohol. The alcohol is distilled to a purity of anywhere between 90 and 98 percent alcohol. Next, the alcohol is diluted down to anywhere between eighty and one hundred proof. This is accomplished by adding water. Since water in various parts of the country differs in taste, different brands of vodka taste different. In the United States, citric acid is the only blender that is permitted to be added to vodka. It is important to note that this law only applies to plain vodka. Flavored vodka contains all kinds of flavor chemical and additives and certainly requires kosher certification. Additionally, imported vodka is subject to the laws of the country in which it is produced.
Some imported vodkas contain glycerin, which, as noted above, may be derived from animals.

GIN
The traditional method of making gin was—and in some places still is—to add raw, dried botanicals to the still as the crude alcohol is being distilled. The heat and alcohol cause some of the flavor in the botanicals to penetrate into the alcohol. After diluting the mixture with water to the desired proof level, it becomes distilled gin. The botanical most commonly used is juniper berries; however, each distillery has its own closely guarded secrets as to the type and amount of botanicals used. Botanicals are generally kosher; however, some of them, such as citrus peels, may come from Israel and therefore may not be kosher due to issues surrounding terumot, ma’aserot and shmittah.

A newer and more common method of making distilled gin is to add already made extracts to the alcohol. This mixture is then called gin. Obviously, alcoholic extracts require kosher certification since they can be made on non-kosher equipment. Moreover, since they are made all over the world, it is difficult to track their place of origin and to be certain that wine alcohol or whey alcohol was not used in the production.

BOURBON
By law, Kentucky Bourbon must be made from a mixture of grains and contain at least 51 percent corn (maize). Rye, barley and wheat make up the rest of the mixture. The grains are fermented, distilled and aged in new oak casks that have been charred. By law, one cannot add blenders to Kentucky Bourbon.

RYE
Any whiskey that has 50 percent rye in the grain blend can be called rye whiskey. Such whiskey is likely to contain blenders.

TEQUILA
While tequila is produced from the agave plant, it often contains oak flavor and glycerin. These items are approved for use in tequila by the Mexican government. In addition, not all of the yeast in Mexico is kosher. Without kosher supervision, it is impossible to know whether the yeast used is kosher or not.

CANADIAN WHISKEY
Canadian law permits flavors and wine to be added to whiskey; these additives need not be declared on the label. It appears that many Canadian companies insert flavors and wine into their whiskey.

Rav Moshe felt that since in alcoholic beverages the ratio of non-kosher wine or other products to liquid is usually more than one to sixty, it is worthwhile to refrain from drinking alcoholic beverages that contain wine, glycerin or other non-kosher ingredients

There is a well-known dispute among the Poskim concerning the exact point at which non-kosher wine is batul. Some contend that in order for the non-kosher wine to be nullified, the non-kosher to kosher ratio must be one to six; others contend that it must be one to sixty. In Iggerot Moshe, Rav Moshe Feinstein takes the lenient position and rules that non-kosher wine is batul when the proportion is one to six. There is an additional halachic dispute whether the one to six ratio of nullification applies to water or to other liquids such as fruit juice and whiskey. In other words, does the principle of batul apply only when the non-kosher item is mixed with water or does it apply when mixed with other substances as well? Rav Moshe takes the lenient position there too and rules that it applies to all liquids. However, in his respons concerning both disputes, he adds that even though he rules leniently on these issues, it is worthwhile to be stringent. Rav Moshe felt that since in alcoholic beverages the ratio of non-kosher wine or other products to liquid is usually more than one to sixty, it is worthwhile to refrain from drinking alcoholic beverages that contain wine, glycerin or other non-kosher ingredients.¹ He writes that he only drank such beverages if someone was making a lechaim and would have been insulted if he did not partake.

In light of the various issues raised, it is worthwhile for the kosher consumer to demand only kosher-certified alcoholic beverages.
