First time poster here! I (23M) want to buy my father (59M) a vintage, the year he is born, 1967, bottle of cognac for his birthday. I haven’t the faintest idea where to start. I have a little bit of money now and would love recommendations on 1. Trustworthy sites for vintages, and 2. What to buy.

Edit: I’m just looking for recommendations, I’m NOT asking to buy alcohol, as i know it is prohibited.

Thank you for taking your time to help out!
