Down to prohibition. For a time you couldn't legally sell alcohol so apple juice was sold under the name cider. Sometimes with handy instructions on how not to store it to avoid it fermenting into alcohol. Then, by the time restrictions were lifted, cider just meant apple juice as far as America was concerned.

(Allegedly)

Not just in UK, but literally everywhere in the world. Apart from US.

As a Frenchman from Normandie, and an uncle producing alcoholic cider, I was always very confused when ordering cider at restaurants. Hard cider is the booze one.

But, in this sense, she's almost certainly referring to mulled cider, which is pretty much exclusively made with the hard stuff, with the some additional flavors and spices, and likely spiked as well.

My personal favorite recipe involves hard cider, cranberry juice, spices, and then spiked with rum.

It's much more fall feeling and alcoholic than either cider alone.

The entire West Country is fuming at both the notion of cider being merely an autumn drink and also it being compared to pumpkin spice

Yeah, you'll usually see that referred to as "hard cider" here. Though, it's worth pointing out that even American hard ciders are sickeningly sweet. There's a pub near me that has Strongbow, and I've become a big fan.

The cloudiness is what makes it AMERICAN, you Limey bastard!

I'm not putting my knob any near a juicer. Fool me once...

Eggnog is delicious, but if I drank it year round I'd put on a hundred pounds

But apples are available year round and cider is a great storage method. It is available year round. Preferences and market drivers cause seasonal supply increases.

Actual eggnog is an affront in the fact of god, but the carton of custard flavored milkshake that Southern Comfort sells every year is pretty excellent. I'm led to believe you can even put booze in it.

Take the nutmeg out of it, that's what no one likes about it. That's basically what custard is, and it's fucking good.

It's like a drinkable pudding.

Cider can be made from all kinds of good fruits (maybe things other than fruits can count as cider, I'm cideroligist)

Then wtf is pear cider?

Meh, let the apple lovers lean into the fact they are getting the good shit.

Another fun fact. Apple seeds are not true to seed. Which means if you plant apple seeds, you will get crab apples.

It's the spices often used in pumpkin pie and other pumpkin dishes. According to the internet, it's a combination of "cinnamon, ginger, nutmeg, allspice, and cloves".

Probably because the most popular use of "pumpkin spice" is in a PSL.
