Has anyone tried or heard of this?  An old timer was telling me he would brew a pot of coffee and then soak is worms in it.  He said you could also put the coffee into a spray bottle and use it throughout the day.  He said the scent of the coffee is an outstanding attractant for bass.  

Nah,I just spit on them

Well they do have those coffee tubes out now. But I don't think it's an attractant at all.

In my opinion it's more of a masking agent.

Drug dealers in columbia would hide there coke in crates of coffee because they couldn't be detected as well by dogs.

have not used it, but saw the show where they were using those tubes

I bought one pack of the new Coffee Tubes just to try it out.  I went back to buy some more at my local tackle shop and they were all sold out.  The tackle shop owner said it was the hottest new item they have stocked so far this year.  I have yet to hear of or see anyone catch a fish with them yet.  One things for sure I like the smell and Strike King has come up with some great colors.  They may have a winner on their hands.
