Conor McGregor's whiskey company, Proper No.12, doesn't appear to be a hit with famous actor Jean-Claude Van Damme.Van Damme recently launched his own whiskey company called Old Oak, and upon its release, the actor shared his review of the Irishman's liquor.According to an article written by The Sun, Jean-Claude Van Damme said this:"Proper No 12 was heavy on my throat when I tried it. It’s not like my Old Oak Irish Whiskey because that is more, what’s the word... smooth. I like it better that way. I don’t know about the quality, I can’t say. I’ve tried them all. Every whiskey is like every woman or man, they all make love differently."Conor McGregor launched Proper No. 12 Irish Whiskey in 2018, and 'The Notorious' is a co-founder of the company.Proper No. 12 is owned by Eire Born Spirits, a company owned by McGregor alongside his manager Audie Attar and Ken Austin.The brand has continued to grow from strength to strength, and signed a deal to become the official whiskey partner of surging MMA promotion, the Professional Fighters League (PFL), earlier this year.As well as signing with the PFL, Conor McGregor's company has launched the Proper No. 12 Irish Apple, an apple-infused Irish whiskey.
