Currently having a discussion with an american home brewer on a Facebook homebrew site and the question is,CO2 tanks for homebrew are they lined inside to stop contamination? He said not in the USA and I agree with him that industrial or domestic CO2 is CO2 but I'm sure here in the UK that our homebrew tanks are lined and not lined for industrial use,thoughts or in the knower's?
