Matcha lattes have taken over British high streets, but experts warn that many coffee chains may be serving low-quality or fake versions. Maria Dawson, managing director of Japanese food brand Clearspring, told the Daily Mail that poor regulation means inferior products are common.
Sales of matcha have doubled in the UK between April 2024 and April 2025, with global sales expected to reach £3.9bn by 2028. However, tea master Keiko Uchida from Notting Hill told The Independent that many high street chains use green tea powder instead of authentic matcha.
Dawson advised consumers to look for bright green colour, a fine silky texture, and a clean grassy aroma. Authentic matcha should taste naturally sweet with umami, not bitter. She warned that dull, greyish powder or a gritty feel indicates poor quality.
The popularity surge has put pressure on Japanese growers, with heatwaves reducing crops and shortages pushing up prices. This has encouraged the spread of fake matcha, making it essential for buyers to check provenance and choose organic where possible.
