I have used the same system at home to reduce unplanned beers. Alcohol-free beers are always in the fridge waiting, and the ones with alcohol in are somewhere much warmer. On the two to three nights a week I want a refreshing malted beverage, this almost always leads to me going for the alcohol-free version.

That said, following your Wikipedia link, it seems that a different mechanic is at play:

> "No product may be favoured over another, which in practice means that the beers are not refrigerated, since otherwise all beer would have to be refrigerated which is too expensive."
