Yeah... as Spills points out, I have tried their stuff. It was bad.
Counter intuitively I actually think that their business should be an encouragement to homebrewers everywhere.
Think about it - taking out the hard parts of getting a liscence etc - you can start a brewery with nothing but a shed, a pile of 60L fermentors and some extract.
Now I know that the lovely valley people are a poor example... but imagine that tomorrow they sold up and an AHB member who knows about temperature control and yeast and what makes beer taste good, bought the place. Without changing a whole lot infrastructure wise... there are brewers on this site who could be pushing out pretty decent kits and bits brews in a couple of weeks.
Give em a year to organise a Happy Goblin style AG set-up for only a few thousand bucks (if their own rig couldn't cut it) and its some AG brews and the ability to make partials on a large scale...
So for me, its not about the kits/extract/AG - Lovely Valley could be perfectly good, they just aren't.
