For me if I could create a clone for the price of a six pack I'd be happy.That way I see it there are some beers that are damn expensive and damn nice. If you could knock out a 20 litre batch of that beer for the price of buying two stubbies, then surely cloning this beer makes sense? Particularly if you've always wanted to be able to drink more of it but couldn't afford it.
For that reason I'd never get hung up on trying to clone something that's cheap and available. But to truly clone a really good trappist beer for example would be awesome.
But answering the question Dupont Saison.
