I'm expecting 'our man at Starbucks' will contribute eventually.
Drinks, hot or cold have long been used to mask unpleasant tasting water.In fact, that other beverage mentioned above, beer, was invented in modern day Iraq because even then water could be dangerous to drink. We've been experimenting ever since, from pine needle tea to something called 'smart water' apparently favoured by cyclists. At $5 a bottle locally, the Lance Armstrong wannabees don't SEEM any smarter. At least judging by the near misses by our 12 speed cavaliers vs SUVs mutually ignoring the local STOP acronyms.

The sad reality is virtually the entire planetary water supply is compromised in some way. It will be a worldwide geopolitical issue in coming decades long after the renewable fuel issue is a historical paragraph.

And these drinks all have a rich social history from buttered tea served by tibetan lamas to Buckingham Palace, even 'on the trail' or in a basecamp.SAKS have a corkscrew, but those can openers probably open as many cans of coffee.

Here is a quizz. What german scientist discovered caffeine( not the peoples who first gave us coffee, just it's chemical properties) and what other vital compound found in another famous drink?

My favourite knife for opening coffeecans is the p 38.
