[pct-l] Sawyer filters and Coffee

[Town Food]

Has anybody tried running coffee through a Sawyer filter?  Does it taste 
different, or remove caffeine or the like?  I'm also curious about other 
drinks, like Gatorade or tea.  Does it clog the filter faster?

It seems like it would be nice to be able to have cold instant coffee in 
my first water bottle of the day, but I drink straight through the 
filter and don't carry any clean bottles.
