Proper No. Twelve Irish Whiskey was founded by Conor McGregor in 2018. The traditional triple distillation method is used to create the ultra smooth blend of fine grain and single malt with notes of vanilla, toasted wood and honey. Mr.Notorious launched his Proper No. Twelve Irish Whiskey brand prior to his fight with Khabib Nurmagomedov, and, although he lost that battle, he has won the war with his phenomenally successful whiskey.
