Good to see someone else is trying them for a second opinion.. only it is only of value for comparison .. if you are a latte drinker? If you are, you could always put 100g away and pull them out in 2 months and see what you reckon? 100g so that you can play around to get it right. I'll have to go back and read my posts using them again.. to get the age after roasting, ratings & comments. I really need to put markings on the grinder so that I can repeat a grind that worked at the time with a particular bean. I suppose I should use some of the Guatemala in intervals, cause I need to know the earliest they come good .. and gauge their improvement right up to the 9 1/2 weeks, as for all I know, they may be past their peak. Golly, if they are past their peak .. I'm looking forward to trying them when they are at their best. Are you a shot .. latte drinker .. or both?
