It never smelt like actual cheese, that part is not true.
It's an acrid, skunky yet fuelly smell accompanied by an almost nail polish remover note that lingers alongside a faint sweetness in the background.
The genetics are still floating around, to how it used to be. I recently grew out Cheesedom, by Freedom of Seeds, and it tickles my memory banks to how Cheese was 20 years ago.
I've tried a few others over the years. The one by GreenHouse Seeds is a recreation, no matter what the description says, and it's not all too close to the cut that was going around ages ago. G-13 Labs have a Mozzarella, but it's not very stable and the beans are likely to give different phenotypes (and not potent enough in effect nor smell, just 'is there').
The FoS Cheesedom however seems to be the one. Almost spot on to how it used to be, and I'd recommend this one if anyone else has been chasing Cheese and getting disappointed over the years.
