Vodka has a pH of around 4.0, similar to whiskey and gin. It is less acidic than beer, which usually has a pH of between 3.0 and 3.5 and many wines, which can have a pH of 3.5.
Mixing vodka with water or fruit juice with a neutral or alkaline pH can reduce its acidity. In turn, this reduces the likelihood of metabolic acidosis, or the buildup of lactic acid, which can lead to rosacea, body fat, tooth plaque and artery plaque, or cholesterol.
The ideal pH for blood is between 7.35 and 7.45. When it remains below 6.8 or above 7.8 too long, there is a severe risk to the functionality of cells and health.
