There's been a subtle change at The Crown.
Andy has always had really well-kept beer. The first time we went in, the BBB is sure we had a pint of Harveys Best on gravity. It was the day we first viewed the house we now live in we thought we'd check out a local pub and chat about what we thought of the house.
It was several months later we actually bought it and moved in.
Naturally, we revisited very quickly (I can't remember if it was the day we moved in or the next day) and found to our delight that it was Dark Star Hophead on gravity, along with 6X, Harveys Best and something like Spitfire. Bit by bit a different guest would appear at weekends, and Andy ran beer festivals 3 times a year (he still does).
At the time The Crown was an Enterprise Inns pub and we asked Andy how he managed to get different cask beers in. "I get a bit of latitude" he said.
A couple of years ago, we noticed that 6X was no longer a regular on the bar - "...only two blokes drank it and they died..."
More recently Timmy Taylor started to appear - first intermittently, now as a regular beer. Always well kept (obviously) good in a pinch for us but not really what we want to drink.
We learned that EI had sold on some of their estate to Heineken. The craft beers on offer changed from Shipyard IPA to Gamma Ray and new keg ciders are available.
Then a couple of months ago, we noticed that now there's nearly always a nice "new" 4% or so pale beer on - and they're often ones we've not seen before. Typically they'll be fairly local - but not always. At the weekends there are typically two or more interesting beers on.
I read quite a lot of beer news from various sources and I'm guessing that, with shift in uber brands, seems to come a culling of cask beers so I'm guessing that Heineken pub estates now care much less about what cask is on the bar but probably don't allow much flexibility in the keg offering.
This would definitely explain the subtle shift (with its attendant improvement) in the cask offering for landlords(/ladies) who have a genuine interest in cask.
I hate that once significant brewers no longer brew but if it means a bit more interest on cask from places we might not always expect - then for me it might be a price worth playing.
