I know the general rule of thumb is two tablespoons for every 6 oz. typically but that is too strong with my drip coffee maker.  I tried just one and even that seems strong.  I'm afraid that I've never tasted what "proper" Cafe Bustelo tastes like and the canister does not have any instructions. :(  What should the flavor profile be?  Very bitter, smooth, etc.?  I want to impress my mother in-law with an awesome batch next time I see her!
