Pro Tips

Always add water to alcohol slowly.
It is best to use distilled or filtered water to avoid clouding.
Allow the mixture to rest for the flavors to marry.

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
