There has been some discussion about whether or not bisphenol A (BPA) or phthalates can be found in coffee produced from a Presso or a ROK. Presso Ltd, makers of the Presso and the ROK, have commissioned Gas Chromatography and Mass Spectrometry tests that have proven definitively that neither BPA or phthalates are leached into coffee produced with either the Presso or the ROK!
Further, since April 19, 2013, BPA is no longer considered a developmental toxin by governmental bodies, and the chemical that once caused so much controversy can now be considered little more than a needless worry when products containing BPA are used in accordance with their directions. California, a leader in the environmental fight for material safety, has delisted BPA as a toxin. Their published list of toxins can be found at http://www.oehha.org/prop65/prop65_list/files/041913P65list.pdf, and the filed court order delisting BPA can be seen at http://oehha.ca.gov/prop65/law/pdf_zip/041913PIOrderBPA.pdf.
We hope this puts the matter to rest, and we look forward to continuing to serve your espresso needs with these fine products!
