This is apparently the original recipe from Havana from backning the day. I normally love a Cuba Libre, but this original recipe is WAY too limey. Even when you cut down the lime, it tastes like a lesser glass of coca cola. You really need a much more flavorful rum in here. I think 0.5 or 0.25 Oz is the correct amount of lime. Or a wedge, hand squeezed. And a better rum.
