The wine saver is perfect as there is no need to drink the whole bottle through fear of oxidization, the wine saver will keep multiple bottles fresh with its spare stoppers and your favourite white wine can be stored in the fridge. The new CellarDine wine saver is made of ABS with a stainless steel body and comes pre packed with two unique silicone stoppers that work exclusively for this set. The spare stoppers come with a easy to use internal button that once pressed side ways can be removed effortlessly from the bottle.
