Hahaha MR-PRESSO in an article about coffee.
Does anyone have ideas as to why instant coffee may have higher levels of lead contamination than regular coffee?
Like does the freeze/spray drying add the potential for it or maybe people who use instant coffee tend to drink more of it or in higher concentrations?
Instant gets much higher extraction than any other form of brewing. Hypothetically, it's more likely to extract trace metals at higher concentrations than other methods.
