Why do most frac packs contain less coffee than they should?
A coffee Frac Pack
The standard recommendation is for 10g per 6oz cup. K-Cups follow this rule, optionally.
When researching frack packs for my office Bunn 12 cup brewer, I find that all I can find are packs that range from 1.5oz to 2.75oz. All suggest this is for 12-6oz cups. Using the 10g rule, 12 cups would take 4.25oz of coffee. This is more than just a "slight" difference.
That’s a great point. As you have said, the weight of coffee in frac packs varies a great deal, and always seems to be on the low side.
Unfortunately, I have very little experience with frac packs. The only time I have used them is in hotels. Yes, the coffee was awful. But I never knew whether the problem lay with the frac packs or the low quality of the brewer itself.
Anyway, in spite of not having an answer for you, I wanted to publish your question because other readers may have more experience with this than I do.
