I have the entire LS collection and they are exceptional. As a rum man I agree with you about the complexity available in aged rums -- and even the early trial versions of Lost Spirits that predate the full-fledged Colonial example are outstanding from a "mouth feel" standpoint. I have routinely trotted them out to put in front of my Scotch-drinking betters, and while a Scotch snob is an impossible conversion target, it's rare to have one not express surprise at what they've tasted. They are all overproof but extremely drinkable. Even the 151-proof "Cuban Inspired" can be sipped, and its texture sensed, which is pretty unbelievable for its alcohol content (notwithstanding its age). Anyway, all this to say this is less fake than other techniques, e.g. sugaring wine. If you're in the Bay Area K&L and Beltramos carry various versions, all $40 or under. Worth a shot!
