They (Urquell) also teach this when you visit them as a bartender (idk if they still do it, but if your pub sold enough Urquell they’d invite you for a tour). They very much have an incentive to make your kegs last less, but they don’t.

I’ve had that all-foam pour and it was actually nice in its own way. Of course I prefer it with a smaller head because I like the taste of it, but the milk pour is super smooth and mild if you’re into it

I also don’t want to know how much money I’ve funneled to Urquell through my local pub lol
