Doc, Second that The Abelour A'Bundah or nearly cask strength is a fine sipping single malt.  A drop or two of clear glacial lake H2O opens it up so fine.  You only have to make sure it gets up there in an unbreakable container like saline bottles that I use for surgery.  Airtight seal with a silicone gasket, pour it in just before you hit the trail and your beverage is very safe. ;)
