Fun Facts

"When mixing alcohol and water, volume contraction occurs, meaning 500ml of ethanol + 500ml of water results in slightly less than 1000ml total."
"Most commercial spirits are diluted with demineralized water to reach bottling strength."
"The formula C1V1 = C2V2 is the standard for dilution calculations."

Formula: V2 = (C1 × V1) / C2
