Is it bad to add water whiskey?

It's perfectly fine and often recommended to add a splash of water to whiskey. This is because water can:

* Open up the flavors: Water helps to release the aromas and flavors in whiskey, making them more accessible to your palate.

* Smooth out the harshness: Adding water can dilute the alcohol content, making the whiskey smoother and less harsh.

* Enhance the complexity: Water can bring out subtle nuances and complexities in the whiskey that might be hidden without it.

However, it's generally not recommended to add a lot of water to whiskey. Too much water will dilute the flavor too much and make it taste weak and watery.

Here's a general rule of thumb:

* A few drops to a splash: This is usually enough to open up the flavors and smooth out the whiskey.

* Never add more than a third of the volume of the whiskey in water. This will make the whiskey taste watery.

Ultimately, it's a matter of personal preference. Some people enjoy their whiskey neat, while others prefer it with a bit of water. Experiment and see what you like best!
