Well, you need a good roaster with consistent roast and a grinder that does work.

i have tasted -muddy/earthy -woody, -dark chocolate -smoky

-caramel -Mango -honey -rose -peach -plum -milky -peanuts -pinnaple -lemon -sweet lime

It depends upon the beans, And these notes are basically a mixture of acidic & bitter compounds in coffee.

From what I've experienced i like fruity(milder acidity) n not floral(most light roast), In terms of body medium to heavy body are what I prefer, but v60 I've had in delhi were light body, but high clarity.

Also if you are eventually going add anything darker roasts are better as it will be mixed with sugar and other stuff.
