- QUESTION: My wife insists that there is a chemical in wine that can produce a
- cancer, that everybody knows about this, even the FDA, but that no one is
- doing anything to protect us. Could you please look into this and let us know
- where we stand? I am sure you can find out the truth.

- ANSWER: It wasn't hard to discover the answer to your question for a great
- many people do know about it and a great deal is being done. To start with,
- the chemical in question is called "urethane," a natural product of the
- fermentation process by which yeast turns fruit juice into wine. It is also
- known as ethyl carbamate and it is not a product of any new technology, with
- some amounts present in many alcoholic beverages, differing significantly in
- quantity from one alcoholic product to another, and even between bottles of
- the same variety or brand. Both the FDA and the Bureau of Alcohol, Tobacco
- and Firearms (I'll bet you didn't know there was one) have sampled some of the
- products on the market. Imported fruit brandies had the highest levels about
- 1,200 parts per billion (ppb), sake next with about 300 ppb, then bourbon with
- 150 ppb. Ordinary grape table wines only have about 13 ppb, but dessert wines
- can contain up to 115 ppb. The problem is that no one knows just how much
- risk these amounts present, for the studies, being conducted at the FDA's
- request by the National Toxicology Program, are not yet completed.
- However, no one is waiting around, and the industry, lead by The
- Distilled Spirits Council of the United States, the American Association of
- Vintners, and the Wine Institute are all pursuing strategies which are
- calculated to lower the quantities of urethane in all alcoholic beverages.
- These include changes in wine growing (lowering the amount of fertilizers
- used), using a new type of yeast in the fermentation process, and making
- modifications in their manufacturing plants and processes. Recent testings
- have shown marked reductions in the urethane contained in recently processed
- alcoholic beverages. For now, there seems little for the moderate consumer of
- spirits to be concerned about, but prudence would seem to dictate limiting the
- consumption of products containing high levels of urethane, such as fruit
- brandies. In general domestic products contain less urethane than imported
- brands.
