HOW HOW MUCH WHISKEY
DOES IT TAKE TO REACH 0.08%?

Conventional wisdom says that it should take an "average person" about 3-4 glasses of whiskey to reach 0.08% BAC... but is that true for you personally? Are you sure?

Factors That Affect BAC

With so many factors affecting blood alcohol content (BAC), it's difficult to accurately estimate how much whiskey it would take an "average person" to reach 0.08% BAC, without knowing  their age, gender, body weight, what kind of whiskey they drank, how quickly they drank it etc. Luckily, a breathalyzer from BACtrack can give you an accurate estimate of your BAC, no matter which factors are affecting you.

Stop Guessing & Start Knowing

Unlike drink charts and online calculators, BACtrack breathalyzers donā€™t use generalizations or rules of thumb that may not reflect you personally.

Instead, they measure the amount of alcohol actually in your breath and then estimate your BAC, with pro-grade accuracy. No other method is quite so fast, convenient and reliable.
