With this handy tool, you can drink your wine and save it, too. Designed to preserve wine's unique flavor, our easy-to-use vacuum pump slows oxidation by quickly extracting air from opened bottles. Just cap your bottle with one of the stoppers, then use the stainless-steel pump to create an airtight seal. When you hear a clicking sound, you'll know the bottle has been securely vacuum sealed. Extracts air from opened wine bottles, then creates a vacuum seal to preserve the wine's distinctive flavor and bouquet. Pump and stoppers work with most standard wine bottles. Includes two reusable rubber stoppers. Set of three replacement stoppers also available. A Williams-Sonoma exclusive.
