Chris,
There should some extreme punishment for handling such a wonderful cup of coffee so cavalierly! If you are going to re-heat coffee in the microwave 5 times before completing it don't bother with such quality to start with. Might I recommend the much cheaper freeze dried taster's chioce. After the third reheat in the microwave you won't notice the difference between starbucks with frothed milk and taster's chioce and evaporated milk from an unrefrigerated can. <img src="images/graemlins/wink.gif" alt="" />

If you can't atleast stop trail side and enjoy the few moments it takes to drink a good brew-up then just keep hiking and drink water - your'e working too hard to afford the dehydrating effects of coffee (or tea, or soda, or beer) anyway.
