Take the guess work out of resealing open bottles of white or red wine. Using a built-in indicator on the stopper and a multipoint airtight seal, the Bartender Sure-Seal Wine Saver Set precisely removes the exact amount of oxygen required without damaging the preserved wine of its natural flavours and aroma, reducing oxidization and prolonging a wine's lifespan. To use, push stopper into bottle, line up vacuum pump with stopper and pump until the indicator disappears. Airtight seal allows bottles to be laid horizontally. If the indicator reappears, it's time to drink your wine, or repressurise. Set includes: 1 x Vacuum pump. 2 x Sure-Seal wine saver stoppers. 3 Piece set. Suitable for white or red wine. Includes vacuum pump. Stoppers include built-in oxygen indicator multi-point airtight seal. Wipe vacuum pump clean with damp cloth, stoppers handwash only.
