I recently started thinking, our morning coffees seem to be exposed to a lot of plastic in the brewing process, including the plastic water reservoir, the tubes that carry the water (even after it's heated to a very high temperature), and even the portafilter has a big slab of plastic that the espresso falls onto before it falls into your cup/glass. Apparently the plastic in the portafilter is intended to prevent your espresso from cooling down too much.
I guess there is also the concern that most plastics also contain various additives, which can leach out into liquids.
From what I've seen, the only thing that can be done to reduce this plastic exposure in a standard espresso machine (e.g. Breville/Delonghi) is to remove the piece of plastic from the portafilter. But it is the rest of the components that concern me.
In this age where we are exposed to microplastics from so many different sources and studies are finding microplastics in people's brains and heart tissue, as well as identifying potential health issues associated with microplastics exposure, do you think it is safe to be having 2 or 3 coffees per day from a plastic espresso machine for the rest of your life?
I think the world would be unsafe if we all stopped our morning coffee intake…
