Filtered Beer & Wine can have Higher Arsenic and Lead Levels
There have been many research publications in recent years detailing the heavy metal levels in alcoholic beverages such as beer and wine, but few of these investigate how the processing of these beverages may influence the levels of toxic metals. The results of a new study by Redan et. al. published in the Journal of Agricultural and Food Chemistry (February 2019) show a clear correlation between the filtration of beer and wine using diatomaceous-earth (DE) filter media and the concentration of inorganic arsenic and lead in the beverage. However, these elevated concentrations can be mitigated through careful selection of DE media or pre-rinsing of the filter aids. Brooks Applied Labs offers a full range of analytical testing services for heavy metals and inorganic arsenic speciation in beverages of all types.
