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?
Just some speculation, maybe sourcing cheaper/multiple kinds of beans? Is instant coffee single source? If it's not it could be that some of the beans that are being sourced have higher lead content. I know for example that lead is a problem in tea leaves if not monitored for, as the plants will take up lead from the soil.
