Wine in British pubs

Again, yes.

Most definitely. Husband tried the beers but I stuck to my red wines. We just returned from our first trip to London -- loved it even with the 93° heat wave. While there we tried the RS recommended Chandos Pub Near Trafalgar Square and St. Martin-In-The-Fields church. Very good food and drink and nice atmosphere.

And there is a much wider choice of wines now in pubs than the old days when it was 'white' and 'red', except in some spit and sawdust pubs as a tourist you probably would not be going to anyway.

The choices seem to be three or four, usually French, Australian, Spanish or Italian.

"Yes why did you think they wouldn't ?"

Because if you're an American and you have never been to pubs in these places, the stereotype is that they only serve warm beers, they don't even have anything else for sale, and that they will tease, yell at, and otherwise abuse anyone who even dares to ask for anything else.

It's similar to the questions posted here about not drinking wine in Italy or France.

Chateau Thames Embankment was Rumpole's favorite.

That stereotype probably was true about forty years ago. There probably are a few pubs still in existence where it would be inadvisable for a man to order wine, but nowhere tourists are likely to find themselves.

The choices seem to be three or four, usually French, Australian, Spanish or Italian.

Or Argentinian wine when drinking at home. One's drink choice can be influenced by social status seeking. Imported can be more prestigious than domestic. That said, a cheap California wine is better than a cheap French wine (in my opinion), and an US or Canadian craft brew can be second to none in the world wide scheme.

Wine has overtaken beer as Britain's most popular alcoholic drink,
research suggests, with supermarkets reporting a surge in sales of
Argentinian red this year.

opinion)

Perhaps if you're drinking the cheap French wine in Oregon. If you're drinking it in France, it's way cheaper and way better than a whole range of price points for California wine. In my opinion. ;)

Argentine wine, especially a good malbec, is great value for money. Because the UK has very little in the way of domestic wine production we get to pick and choose and be fussy over what we do drink.

Our limited pub experience was getting wine in those little single-drink bottles. But it was just my wife ordering a single drink. She'd ask for a pinot grigio and sometimes get one, otherwise a chablis or sauvignon blanc or such. (I, like a real he-man, was having beer.) If we'd ordered a whole bottle we might have had more choices. And this wasn't in sophisticated London, to be sure.
