Barista Tears sells a single 50 ml airless pump for US$45. One press doses 0.9–1 L of demineralised water, and the maker says a bottle yields up to 17 gallons. The label lists water and three salts; the maker describes those as part of a proprietary 75-plus mineral composition, asks for base water under 15 ppm, and states the product is not safe in a traditional espresso machine. The first run is sold out, with a restock dated 23 October, promoted through the brand's own Instagram — no YouTube video covers it yet.

Quotes

“VERY fast extracting (you have to reduce temps and grind coarser), extremely crisp acidity, clean mouthfeel, and most important - insanely glassy and articulated clarity.”

“We’ll never pay for endorsements, sponsor champions, or hand out free product to influencers. Every opinion you read will come from someone who bought it, just like you.”

“This really reads like a paid review, though I do believe you that it's not”

“Careful throwing around the “it extracts faster” trope though, there is no credible evidence that mineral content will effect the extraction rate and very minimal evidence that it effects even the compounds extracted.”

Voices

Verdict · Reddit · r/pourover — Four months, 99% of brews — The reviewer writes that he has used it almost exclusively since, dosing one pump into RO water, and has largely stopped using his own custom mineral mixes; the thread drew 196 upvotes and 239 comments. See the review.
Objection · Reddit · r/pourover — Free pre-production units — The top reply, at 130 upvotes, says the post reads like a paid review; the reviewer discloses that he received pre-production minerals and a GA version free, was not paid or asked to review, and reports no financial ties. See the reply.
Objection · Reddit · r/pourover — The extraction-rate claim is contested — A 34-upvote reply to a first-impression post says there is no credible evidence that mineral content will affect extraction rate, that few studies exist, and that those which do point the other way. See the reply.
Claim · Maker — Natural minerals, not lab compounds — The maker argues that lab-grade compounds taste flat and hollow, and that naturally sourced minerals elevate the cup; no independent test of that comparison was found. See the about page.
