Glass bottle water found with 50x more microplastics than plastic bottles France's food safety agency tested 56 beverages. Glass bottles had up to 50x more microplastic particles per liter than plastic bottles or cans: - Beer: 83-133 particles/L - Lemonade: 45 particles/L - Cola/soft drinks: 31 particles/L - Iced tea: 29 particles/L - Wine (cork seal): 8 particles/L - Water: 4.5 particles/L Plastic bottles had just 1.6 particles/L for water. Bottling process made a big difference: - Uncleaned caps: 287 particles per liter - Cleaned caps: 87 particles per liter (A 70% reduction just from rinsing) The source is not the glass. It's the painted metal caps. Wine with cork had nearly zero contamination We are actively testing all bottles for microplastics on Oasis app
