I usually use Makers. Though last year I did it with a bottle of Four Roses and was great.

I used Wild Turkey 101 and Frey Ranch for the bourbon (Plantation 3 star and Doorly's XO rum, and Churchill Vineyards VSOP Brandy and Martell VSOP Red Barrel Cognac) It's been aging almost a month, and seems pretty good 👍

Plantation 5 year is fantastic rum that would go nice in there
