If this https://orbmedia.org/stories/plus-plastic/ is the website that posted the results (weird site - what's with all those huge/fancy animations?): I keep seeing small plastic bottles (in the animations) => does San Pellegrino sell it (as well) in small glass bottles? (or are the small ones only plastic/PET)?
No mention of which variant(s) (glass, plastic, both?) were tested, right? (or I haven't been able to find the statement)
