I think 2 weeks off roast is close enough to 'fresh' that the difference is going to be subtle. I'd love to see an experiment like this with 3-day old vs 2-months old. I'd guess most people could tell in that case. And maybe then bring that two months in and see where the cutoff is that people can/can't tell. I'll guess it would be 3-4 weeks or so for most subjects. I've never heard of a "triangle test" before but I like that format!
