If there is a customer niche that hasn't been met by the Fullers range - for a distinctive pilsner that is - there's at least a good argument for developing something.
The UK experience thus far has not been that encouraging. Neither an ersatz 'lager' (this series entertains but doesn't inspire
http://boakandbailey.com.../10/ersatzsteiner-pils/ ) nor 'merely' a clone of a good pilsner is going to do.
There are some rather good lagers around -
http://www.sabotagetimes...e/top-10-summer-lagers/ lists some (I've tried a couple of these - Bredog beers though I found far too gassy), and Camden Town Brewery's Hells lager I've enjoyed
http://www.camdentownbre...y.com/year-round-beers/ at the brewery bar. It's clear there is a good market that is out of the more normal Fullers range. I've no doubt that the brewery can and should innovate and develop. Discovery was aimed I thought at the cross-over market, and Wild River is a good example of development and a beer that stands out from the hoppy competition.
So something with something of the biscuitiness and dryness of Chiswick, but a lot crisper, would be one to work for.
