Gonna beat a dead horse. Keep ALL pipe tobacco out of the same humi as your priceless puros. Also, don't mix "natural" cigars with " flavored" ones (Acid's and such) because they WILL impart funkiness on your other cigars. I know it sounds impractical, but each of the three types must be separated. I keep my pipe tobacco in a mason jar as suggested by other folks on this thread. It's always worked for me.
