Sola / Terra
Every plastic component your brewing water touches is a leaching point. Hot water pulls microplastics out of HDPE carafes, ABS grinder hoppers, and silicone gaskets — and nanoplastics now show up in human blood and tissue.
Terra is a pour-over kit designed around four inert materials — borosilicate glass, 316L stainless, high-fire ceramic, and natural fiber — with no plastic anywhere in the brew path.
This is a side track, not an active build. I'm documenting the idea here so it isn't lost. If you're interested in materials testing or early access when it does move forward, get in touch.
