I ordered two different kits to not only compare the methods, but roast profiles as well. To my taste, 19grams was comparatively the darker roast profile. It was fascinating to experience the trade-offs between the different methods. I'm also so glad 19 grams included their own decaf, which was the favorite and I'm curious to find out its method. I will think of it next time I'm looking to buy decaf. Delicious!!
