Birch water, also known as birch sap, comes from the trees of the Betula genus.
While only recently gaining popularity in the United States, birch water has been consumed for centuries in Northern Europe and China due to its potential health benefits (1).
It's also used in cosmetics and other skin care products.
This article tells you everything you need to know about birch water, including its benefits and downsides.
What is birch water?
Birch water is the sap of birch trees and harvested in early spring.
During the winter, birch trees store nutrients that are later released into their sap.
When tapped, birch water is a clear, colorless liquid with a slightly sweet taste. After 2–3 days, it begins to ferment, developing a more acidic flavor (3Trusted Source).
It's consumed on its own or made into other products, such as syrup, beer, wine, and mead.
Today, bottled birch water is available online and in stores. Keep in mind that commercial birch products frequently harbor added sugars and flavors.
