Well obviously but why the comment on moving the fridge shelves for only a few hours?
You don’t have to drink it in one go ! That’s why it’s in a keg !
Don’t know what sort of fridge you have but 5L of beer is not going to chill in a few hours, also I’m not then going to drink 5L allin one go.
Very simple moving one shelf for a few hours !
Because I like to order a variety of beers and enjoy the odd ‘alcopop beer’ so why not? Unfortunately 5L kegs don’t fit in most fridges unless you re-arrange the shelves
