190 alcohol proof refers to a measure of the strength or potency of an alcoholic beverage. The term signifies that the beverage contains 95% alcohol by volume (ABV), making it exceptionally strong and concentrated. This level of alcohol content is often associated with high-proof spirits, such as grain alcohol or pure ethanol, which are primarily used for industrial, scientific, and medical purposes. The term "190 alcohol proof" serves as a stark reminder of the intense potency that certain alcoholic beverages can attain, underscoring the critical need for responsible handling and awareness of their potential risks.

Due to its extremely high alcohol concentration, beverages labeled as 190 alcohol proof are not meant for casual consumption and are typically considered unfit for human consumption without significant dilution. Such potent spirits are often used in controlled settings and industrial applications, including solvent extraction, laboratory work, and manufacturing processes. It's important to handle substances of this strength with caution and adhere to strict safety protocols to ensure proper handling and use.
