According to one study, milk proteins bind with tea's tannins, reducing their astringent and bitter taste. This process, however, does not neutralize the tannic acid in tea, but instead binds to the polyphenolic compounds responsible for the astringent flavor and other characteristics.

Historically, milk was added to tea to prevent delicate porcelain cups from cracking under the heat of boiling water, but today it is prized for its effect on flavor. So, what does milk do when added to tea, and what happens at a chemical level to create that creamy, smooth cup?

Scientific studies reveal that the interaction between dairy proteins and green tea catechins is complex and subject to conflicting evidence. The long-held concern is whether adding milk to your vibrant green drink, effectively, does milk neutralize matcha's significant health properties, or if it's simply a myth.

According to a 2025 news release from the Royal Society of Chemistry, adding milk first to a cup of tea is scientifically the superior method for achieving a better flavor profile. The answer to the age-old debate of why should milk go first lies in a blend of history, physics, and chemistry that ensures a smoother, more balanced brew.

Adding milk to tea is a time-honored tradition for many, dating back centuries as a way to soften the beverage’s flavor. But beyond tradition, **does milk neutralize tannins in tea**, and what are the actual effects on both taste and the drink’s health properties?

According to some studies, the casein protein in milk can bind to tea's polyphenolic antioxidants, potentially reducing their beneficial effects on the body. This has led many to question: does putting milk in tea make it less healthy? The answer is more nuanced than it seems, with ongoing debate and conflicting evidence surrounding this common practice.

The science is conflicting on whether milk compromises tea's health properties, with some studies suggesting milk proteins like casein can bind to tea's potent antioxidants, affecting their activity. This has led to widespread debate and confusion for those who enjoy this classic beverage.
