FREQUENTLY ASKED QUESTIONS
Clos du Bois Wines
- How should I store my wine?
- Are your wines organic?
- Are your wines gluten-free?
- Why are you testing alternative closures?
- Why do crystals sometimes form in wine?
Store all wines in a cool, dark, slightly humid place free from dramatic temperature changes. Chill white wines 1-2 hours in the refrigerator or wine chiller; serve at around 55° F. Red wines should be served at about 62-65° F. Chill for 15-30 minutes before serving to achieve “cool room temperature.” All opened wine should be corked and stored in the refrigerator. Return reds to cool room temperature before serving.
Our wines are not certified organic, but we practice very eco-friendly practices. We’ve been awarded for our commitment to the environment and our sustainable and fish-friendly farming practices. Read more on our Sustainability page.
We do not test our products for gluten. However, to our knowledge our wines do not contain it. Where one’s health is a concern, we always recommend consulting with your physician.
We use both traditional wood corks and alternative closures. For a few years, Clos du Bois and several other super-premium wineries have been testing a variety of alternative closure products to attain an even higher standard of consistency and quality. Synthetic corks preserve the method of opening a bottle of wine with a corkscrew, while eliminating the spoilage that can occur from leakage, oxidation and cork taint (a microbial growth on natural cork that leaves the wine tasting like wet newspaper). Synthetic corks cost about the same as our standard wood corks and help to eliminate these adverse effects.
Crystals discovered at the bottom of a bottle or as deposits on the bottom of a cork are probably potassium bitartrate, commonly referred to in Europe as “wine diamonds.” The same ingredient as Cream of Tartar, tartrate crystals look very much like glass but are completely harmless and occur naturally in wines. Tartaric acid is the primary acid found in grapes. In wine, tartaric acid binds with potassium, also occurring naturally in grapes, and sometimes forms potassium bitartrate crystals. To ensure that the crystals are tartrates, take one of the crystals and dissolve it in hot water or crush it with the back of a spoon. If you find tartrates in your wine, simply stand the bottle upright, undisturbed, until the particles settle to the bottom of the bottle. Then pour the wine slowly into a decanter or wine glass.

Inspired by trips to France’s finest wine regions and his children’s French studies, founder Frank Woods decided the name Clos du Bois best expressed the French influence in his winemaking while incorporating his family name. Loosely translated from the French, the phrase means “vineyard of the woods.” “Clos” here pertains to “fenced or enclosed field; orchard; vineyard." “Bois” translates to “wood” or “woodland.”
