## Whiskey Dilution Formula

The following formula is used to calculate the Whiskey Dilution.

WD = (W * (BP / DP - 1))

Variables:

- WD is the Whiskey Dilution (amount of water to add (oz))
- W is the amount of whiskey (oz)
- BP is the bottle proof
- DP is the desired proof

## How to Calculate Whiskey Dilution?

The following steps outline how to calculate the Whiskey Dilution.

- First, determine the amount of whiskey (oz).
- Next, determine the bottle proof.
- Next, determine the desired proof.
- Next, gather the formula from above = WD = (W * (BP / DP – 1)).
- Finally, calculate the Whiskey Dilution.
- After inserting the variables and calculating the result, check your answer with the calculator above.

**Example Problem:**

Use the following variables as an example problem to test your knowledge.

amount of whiskey (oz) = 30

bottle proof = 80

desired proof = 40

WD = (W * (BP / DP – 1)) =** ** ?
