Dear Dr. Vinny,

I'm using the Coravin wine system. What's the best way to pour an older bottle of wine without stirring up the sediment? Is there a good way to filter out the sediment without hurting the wine?

—Jonah, Redondo Beach, Calif.

Dear Jonah,

Great questions. For readers who haven't heard of it, a Coravin is a device that allows you to pour wine from a bottle without removing the cork. It uses a hollow needle and pressurized argon, an inert gas that protects the wine from oxidation.

No matter how you serve an older bottle of wine, the key is to disturb the sediment as little as possible. Typically, it’s advised to take a bottle out of the cellar’s rack and let it stand upright for a day or two to allow the loose sediment slide to the bottom of the bottle before opening it.

Coravin actually sells a special needle for older bottles; it works the same, but the pour is slower. Using short pulses—as you would normally—is still advised. If there’s any sediment swirling around in the wine, it should pass through the needle, so keep that in mind while handling it.
