I drink 'proof (overproof) rum and water. Nowadays, proof rum is only 126. Back in the day the label read "guaranteed full strength"
I worked at Appleton and at that time "full strength" was about 165 - 170 proof. To be stronger than other rum producing countries's 151 proof.
It was and is till this day (in the hills) it is each drinkers taste that determines how much water or "chaser" to add.
When I pour drinks for my work crew (don't tell OSHA) , I pour straight 'proof rum in one glass. A "chaser" (ting, ginger beer, water, etc) in a bottle and a bowl of ice. Each man make his own.
Me no whan cut de rum and mash up de mahn drink
