Ron Cartavio XO is the top of the line for this Peruvian rum maker. It is now noted as being an 18 year old rum – it is no longer labelled as a Solera system rum. I reviewed their 12 “Year” Solera rum a while back and found it to be pretty average. Other than that my own experience of Peruvian rum has been with the frankly abominable Ron Millonario XO.
