Black Cock is actually a brand of rice whiskey, or rather a spirit, I don't think you could call it whiskey without the Chivas Brothers turning in their graves!!!
I purchased a bottle on a recent trip to the supermarket and upon consumption, it felt like I was drinking bleach. The burning was followed by a palsy-like sensation as my facial and bowel muscles slackened!! Suffice to say I won't be putting any more black cock in my mouth in the foreseeable future.
