What you’re doing is the best. Tasting by the pot method.

Based upon your comments, which are quite good, about the Panamanian coffee, I would suggest that the next time you go to the Good Company, have them roast you some additional Panamanian with a lighter roast. This should reduce the bitter taste somewhat.

Also, I would suggest that when you have left enough of this batch of Panamanian for a couple of pots, take these beans and put them in an air-tight continer and save them until you obtain some Panamanian that have been roasted with a lighter roast.

This way you will be able to compare your tastings of the different type of roasting. The burnt marshmallow taste also suggests a to heavy of a roasting of these beans.

Keep it up and please keep sharing your thoughts. Keep in mind that the weather can also play a part in the tasting of the ful cup of coffee.

Also, do you make your coffee with tap water or do you use bottled water. The water can also effect the taste of the resulting cup of coffee.

For your blog, continue to make your coffee in the same way that you always do and in your own words state your results. Keep it up.
