The conclusion: Jamaican Blue Mountain, Wallenford Estate, peaberry

You may have noticed by now that we did a u-turn on the roast that we decided was optimum for this coffee when it came down to it.

This is a classic example of how a roast changes as it ages. Test roast 5 seemed to raw and harsh the first time we tried it, but some 13 days later it trumped the rest; with slight sooty notes rising in the darker roasts as they aged.

Test roast 5 is the profile we are running with. Just be sure to allow 10 days at a minimum before you open it.
