Hmmmm that is more difficult that one might think...for me.
I was never a bottled beer drinker.
When I was first old enough to get served in a pub, about 16, I didn't have a car nor did I have much money. All the locals I could get to were in the Watney's Red Barrel stage of keg bitters served under top pressure...not that I knew any difference back then.
A bit later the Real Ale movement appeared and many pubs started selling proper beer and I had transport.
Real beer was and hopefully still is very regional in character....I lived in the south and in London and only went oop North two or three times in my life.
Lastly I have been over here for 40 years and after the first experience of Molson and Labatt basically stopped drinking beer until the craft beer movement got going here.
My questions to you are. Do you have a clientèle who will drink draft beer at cellar temperature? Perhaps 40 to 45 deg F. Will they drink beer that is much less carbonated that Canadian beers usually are? I have found that even a couple of drafts I can get in certains pubs here Fullers ESB and Fullers London Pride both of which I used to drink in the UK when served here are served far too cold and because of the shipment method under pressure which of course leaves too much gas in the beer.
Maybe it is for you to take a vacation in the UK with mrs Canuck doing the driving and you doing the drinking. Maybe a look at
