Thanks so much, everyone! Sandra, I did get your response (thanks twice!); but after reading through the answers here, I think that I might have the industrial strength. I didn't think about that before, but the stuff I have is REALLY strong. Too strong. I'm going to buy some of the lesser strength kind tomorrow - that hadn't even dawned on me. Thanks again, everyone!
As for the coffee packets, I am going to make some of these as well as cocoa - maybe even some together and they can be mocha. I think they'd make really cute, practical stocking stuffers; and I'll probably charge $3.00 or 2/$5 for them. We'll see how they go.
