ACIC Cork & Closures in proud to offer top quality Natural Cork to meet your needs. Below are our standard sizes and washes. Feel free to contact us if you have any questions.

Wine corks should be kept in sealed bags placed in sealed boxes which will provide the best protection from contamination. We recommend that leftover or opened bags be rolled up and taped or zipped tied closed. Boxes of corks should be kept in a cool, dry area, to avoid temperature fluctuations and exposure to light. Corks should be used within a 5 month period from the production date on the box. ACIC offers free re-conditioning of our corks with a few limitations.
