This has been discussed before on other forums; I remember a fairly good statistical analysis of it ... if I can find it, Ill post a link. *In a nutshell and from memory, the maths works out that theres a heckuva lot of variation for any blend component thats less than something like 25 or 30%. *The implication for blending is that keeping it simple is probably going to keep the flavour more consistent. *

Another level of complexity is that different beans are of different sizes and weights; presumably there is some separation because of it in the bag and in the hopper. *For example, if you make a blend of 50% maragogype (screen size = 20+) and 50% mokka (screen size <10), how will the blend turn out when you tip it into the grinder? *Will the mokka tend to settle into the bottom of the bag and, so, end up in the top of the grinder when you tip it out?

Cheers,
