Mr. Haeger of texas coffee peeps coined this term 'virtual cupping groups.'
Take a few samples of different coffees, or even better different roast profiles, and then send them out to several friends to blind cup them. Since they won't know cup contents, it's like having a virtual cupping table where nobody can smirk or grimace to influence the rest. The charm is that you get honest unbiased feedback from several sources at once on what you may have thought was an amazing cup or a severely defective one.
Sure it's a fun idea, but I do miss comments like the other night when a cohort smelled a green coffee sample and alarmedly said 'This smells like guinea pig's bedroom!'
