Here is a Nightcap review from the other site and it sums up this beer perfectly. It was by far the worst beer CS has made, I'd drink the buttery Persicas all day before a Nightcap. If the beer drinker doesn't hook you up I have a few bottles I am never going to drink.
Appearance - Murky deep reddish brown body. Medium khaki head. Medium collar.
Smell - Lots of coffee. Sharp acidity. A little vinegar. Chocolate.
Taste - Intensely sour. Coffee. Sour coffee. Sourness builds. Coffee, roasted malt, and sourness.
Mouthfeel - Unpleasantly sour. Harsh.
Overall - So you're driving for hours on the highway and need some coffee. You stop at a 7-Eleven and the cashier has 4 teeth and grease stains on her shirt. You pour the coffee, even though you know it was made days ago with the cheapest, largest container of pre-ground coffee with a "Best by" date of 2003. In one sip, you taste an intense sour and bitter low-quality coffee with just a hint of roast from the cigarette ash that the cashier sprinkled out of the spite she has for the customer. Nightcap.
