The website, in terms of site age, is less than 2 years but this supplier does accept PayPal and credit cards. If you choose to purchase from this supplier, make sure you use the aforementioned payment methods to ensure a safe business transaction.
We do have suppliers here on SaleHoo that offer wine making supplies, but they only accept wholesale orders. The first 2 suppliers are based in the UK and the last one is based in Belgium.

These 2 dropshippers are the only suitable ones I found. Once again, please use safe payment methods when purchasing from suppliers especially for the first few orders.
All the best!
