Personally, I am of the opinion that the coffees roasted by Mr. Gardelli or Wendelboe deserve 6 stars.
Yes, it really is that good. No actually it's not acidic unless you dexterate it.
I can't say for 100% whether Gardelli or Wendelboe is better. But I can say that you will 100% not go wrong when you taste them.
As a bonus, their coffees are very easy to prepare (meaning, you can get what is in the description from those coffees without much effort, which is not always the case with all coffees).
Although Kenya Karinga only has two "flavors" specified, it is actually a coffee with a relatively rich spectrum of flavors. So don't be fooled by that. By the way, mine is excellent even almost a month after roasting, it doesn't affect the quality, the packaging is more than good enough.
It is expensive? Yeah it is.
But it's also adequately good.
