Should you subscribe, note that Davids' point system runs at least 7-9 points higher than SCA scoring system, IMHO. Others may disagree. http://www.coffeereview.com/interpret-coffee/
<Edit: see Dan's post below>I have never been able to ascertain if growers pay to have Davids review and publicize their coffees. I assume so but don't know that factually.
Ken's scoring system has mutated over the years, much like a famous Australian wine judge, James Halliday, www.winecompanion.com.au
. I've yet to taste a coffee or a wine from either one that I haven't marked down by at least 5 points, and in some cases by more than 10 points.
One factor to consider is that we're all getting old (in Halliday's case ancient) and our palates simply don't work as well as they did when we were at our peaks in our 40's and 50's. I do a lot of reference cupping, and I know
that there are flavour nuances I can no longer detect. Getting old sucks, except for the alternative. Basing your buying decisions on ancient guys with buggered tastebuds is also likely to lead to suckage.
