Nomacorc Synthetic Corks / Bag of 1000 / No 9 x 1-1/2: Quality Wine and Ale Supply and Nomacorc have joined forces to offer you the #1 synthetic cork on the market! ''Whats so special about these corks?'' you ask. The answer is the manufacturing process. Other types of synthetic corks are injection molded which is a batch process that produces corks with variations in density and cell structure size resulting in inconsistent protection of your wine. Nomacorcs are made by a unique, patented, co-extrusion process that binds the interior and exterior sections of the cork by heat adhesion. Extrusion molding is a continuous process that provides a very consistent quality, and every cork is exactly the same. Nomacorc is simply a better closure because its uniform, small, closed cell structure creates a better barrier from oxygen and preserves the quality of your wine. They have made for us a 9 x 1½ cork, printed with the Nomacorc logo. Weve tested the corks and they work best with floor corkers but can be used with hand corkers too. These corks seal instantly and the bottle can be inverted for storage directly after corking. You can also use any common corkscrew to open your wine bottles. This is modern technology that preserves your wine and we are pleased to be able to offer it to you. Recommended for use with all floor corkers and also for twin lever corkers. These corks will provide at least 5 years of wine protection during aging.
