But the website says the bottled beer is filtered (and therefore suitable for vegetarians as it didn't contain isenglass). Which might suggest they have to re-pitch the yeast? And it's likely they would repitch with a specialised bottling strain? So is culturing the yeast in the bottles a waste of effort?
They bottle their beer themselves, so it would make sense to reuse their own yeast. I've isolated yeast from a bottle of 'Proper Job'. It's a nice strain for an IPA. Neutral conditioning strains, which a contract packager would use, are noticeably bland.

I was not aware of any filtration there. They have a centrifuge, which I saw on the tour in 2015, but maybe something has changed?

Centrifugation is a filtering method commonly used by commercial breweries. Some even use it as a 'pre-filtering' procedure, to avoid clogging their downstream filters. The bright beer is then primed, and inoculated with fresh yeast, for bottle conditioning.

Changed? No idea. But their Web site says all but their cask beers (which are fined) are filtered.

I've googled around and it looks like they've introduced a filter system since I went.

Filtered or not, it is the same yeast, this has been confirmed by Roger Ryman on several occasions. Like John I have used bottle conditioned St. Austell yeast and have a starter going now !!

They sell a St Austell 'Proper Job' recipe pack here which they claim was reviewed/judged by the creator.
It's spot-on (at least to my taste).

Made it several times. Last time I took a few bottles on holiday and did an A/B comparison with Proper Job from a St Austell pub, pretty much identical. Needs a longish conditioning time, too sweet initially from what I can remember. I'll see if I can dig out the recipe.

(oops looks like I've got 2 accounts on different computers)

Here's the recipe. It was originally just 3kg DME as fermentables, I converted it to AG and added a bit of Caramalt in to darken it a little to get the 14EBC, you could just use all Maris Otter.

----------------
Batch Size (L): 20.0
Original Gravity (OG): 1.056
Final Gravity (FG): 1.014
Alcohol by Volume (ABV): 5.50 %
Colour (SRM): 7.1 (EBC): 14.0
Bitterness (IBU): 53.7
Brewhouse Efficiency (%): 70
Boil Time (Minutes): 60

Grain Bill
----------------
4.900 kg Maris Otter Malt (97.03%)
0.150 kg Caramalt (2.97%)

Hop Bill
----------------
9.0 g Chinook Leaf (11.4% Alpha) @ 60 Minutes (Boil)
9.0 g Willamette Leaf (7.1% Alpha) @ 60 Minutes (Boil)
12.0 g Cascade Leaf (7.8% Alpha) @ 30 Minutes (Boil)
9.0 g Chinook Leaf (11.4% Alpha) @ 30 Minutes (Boil)
9.0 g Willamette Leaf (7.1% Alpha) @ 30 Minutes (Boil)

FWIW, It's my understanding that the OG on that recipe is 'slightly' higher than the real thing, and therefore the FG too, depending what you want to fettle around with for alcohol from priming. I reckon there may just be an early FV hop addition of chinook in there too. Not that any of this will ensure a closer or better result, but there you go.
