I found the Don Papa 7yr two years ago in NY, and it was the best rum I've ever had. I bought four bottles on the spot. It was probably a year later before I found out there was a 10 year version as well, so the hunt began. Eventually I stumbled upon Chips Liquor, where I was able to order the 10 year and have it delivered directly to my home. The 10 year did not let me down. It is still a fantastic sipping rum, just as the 7 is, but it has a slightly more refined, grown up taste, with ever so slightly more alcohol bite (slightly higher alcohol content), and a more pronounced barrel flavor which cuts back some of the sweetness of the 7 year. This bottle (and my remaining 7 year bottles) will be stored separately from my other rums so unwitting guests don't pour a glassful to waste it in a mixed drink, as this really deserves to stand on its own, maybe on the rocks.
As for Chips Liquor, I can not speak more highly of their speed of delivery and care in packaging the three bottles that they shipped to me across the country. I would not (and will not) hesitate to order from them again.
