I have...let's see here:
Doorly's XO - 6 to 12 years, aged in used Oloroso sherry casks! Beautiful rum!
Dos Maderas px 5+5 - aged 5 years in oak barrels in Guyana and/or Barbados, later shipped to Spain to be aged in a two part aging process; 3 years in barrels formerly containing "Dos Cartados" Palo Cortado sherry. and 2 years in barrels formerly containing "Don Guido" Pedro Ximénez sherry. One of the nicest rums I've had!
Ron Matusalem Reserva Solera 15 Year - Aged in the solera method; where the still is only half emptied and the new batch is combined with the old batch and the aging process continues. Never is the still empty! Most optimistic of them!
El Dorado 15 Year - Totally worth the trip and the money! PERIOD! That's all you need to know!
Mount Gay Eclipse Silver (Blanco Rum) - I've only had this in a mojito and a margarita. I'll taste it neat and let you know!
