I have been using closures from diam-closures.com for a while now and I must say that I am very impressed with their quality. The closures are sturdy and easy to use. I have had no issues with leakage or spoilage of my wine. The customer service has been excellent as well. I would definitely recommend diam-closures.com to all wine producers.
