The moment you open a bottle of wine, exposure to air begins to change the wine's flavor, color and aroma. Pek Preservino products use Argon gas to Lock in Freshness. Our new Champagne products are the first in the world to protect the Bubbles and Flavor of your fine sparking wines. Open a bottle today and revel in the same delicious taste many days later without spoilage. Preservino allows you to open your fine wines more often, knowing that you'll enjoy every drop.
