Prior to moving to AG the last dozen kits i brewed were all using the same base kit to which i added specialty grain and hops and used a good dry yeast.
The base kit was Coopers Lager. I brewed english ales, APAs, stouts and porters. I actually won a competition with a kit beer and beat several AG brewers. The judges were gobsmacked that the beer that won and the others i entered that placed were kit beers.
Recently i snuck a kit beer, the first i had brewed in 5 years, into a local case swap. I didn't tell anyone that it was a kit beer and received a lot of positive feedback. It was a sneaky attempt by me to get some blind judging and unbiased feedback on a kit beer. A lot of brewers on this site will poo poo kit brewers but very few would actually be able to pick it in a blind tasting (at least, that is my current theory). When i let the cat out of the bag (airlock) the lads were a little shocked. I did use Coopers sparkling ale as a base instead of the lager, added extra extract, crystal malt and roasted malt plus colombus hops. And a liquid yeast.
What may surprise people more is that the result of this has me thinking that when i am time poor (more often than not), I will happily brew another kit beer. I have ordered the extract already.
My golden ale started out life as a kit beer and the recipe for it is in the notes section below the AG recipe -

I noticed yesterday that the recipe for it and my Landlord are in ianh's kit spreadsheet, something i was not aware of.
