LOL, those are cheat kits for homebrewers, and pretty poor ones at that. It's not how a competent homebrewer makes beer, let alone a commercial brewery.

Someone has sold you a fairytale about IPA production because they don't like the style.

(edit - you'll notice at those shops they are selling all sorts of styles as concentrates, including "Polish hopped beer" - https://browin.com/shop/beer-brewing/coopers-concentrates )

These are small fish, the big fish but beer concentrate tech from https://brewvo.com/

Which is not about brewing from concentrate like the home brew kits are, but brewing to concentrate and shipping like that for dilution in a bar, and it doesn't sound like it's in production yet.

Not something I'm interested in. But it certainly doesn't support your weird assertion that IPAs in particular are all made from concentrate.

I think you have a number of things mixed up in your head here.
