Quick facts

Matcha is less acidic than coffee -- but it is not alkaline
Brewed matcha is mildly acidic at pH 5.6-6.3 (Najman et al., Molecules (2023)). Brewed coffee sits around pH 4.85-5.1. Because pH is a logarithmic scale, that gap means coffee delivers several times more acid per cup than matcha -- a real difference, even though neither drink is alkaline.
Second lever: caffeine. Matcha contains roughly half the caffeine of a cup of coffee, and its L-theanine content produces a slower, steadier release. For people who experience jitters, crashes, or digestive discomfort from coffee, the combination of lower acidity and lower caffeine load is often the meaningful difference.
