I have noticed this, before the floods. It definitely was lacking in appearance and depth of flavour. Too damn clear for a cask beer, - absolutely crystal shining bright. I agree cellarmanship can wreak havoc or do the greatest good, depending on who looks after it. As a natural product, some variability is expected. I have had this happen with other breweries beers, when there were such things as strikes or distribution difficulties. Bass products, Wilsons, and Thwaites having done so, and I saw first hand in the pubs cellars the adaptations to fit the handpumps to the different fittings of the bright beer containers (not strictly kegs, AFAIK). Having been sold Sov once or twice when I wanted cask, thats where I get the flavour hints from. You never know....... (actually, you usually do, lol!). Your round, anyway,,,cheers!
