Only if you use corks and not plastic-lined caps, a somewhat counterintuitive finding. This French study finds that contamination with microplastics (MPs) is higher in glass bottles with plastic caps than in plastic bottles. The MPs matched the plastic composition of the caps. The authors suggest that cap abrasion during storage drives contamination.
What about wine with screw caps that have a plastic liner? And why do sodas and lemonade have higher content than iced teas, which often also have lemon flavouring. This study raises more questions than it answers.
