It’s not about a flavoured beer - there’s plenty of em. This is about a concentrated form of juice you usually dilute in water. You put it into beer, it turns reddish-pink and a lot of people preffer to drink it that way
Pubs in the UK used to (or still do?) have blackcurrant and lime cordial for this.
“Lager and Lime”, “Lager and Blackcurrant” and “Cider and Blackcurrant” were pretty common 20-30 years ago. A shot of cordial (concentrated juice), then filled up with lager beer.
There was also orange cordial behind the bar, but nobody ever drank “Lager and orange”. I believe it was some form of crime.
There’s also snakebite, which IIRC is Lager, Cider, and a shot of blackcurrant cordial. A great drink to get you off your tits when you’re young.
From where I lived, just the lager and cider together was snakebite, and with blackcurrant it was a “snakebite and black” - but I think there was a lot of regional variety (in the UK, at least).
I have heard lager/cider/blackcurrant called a snakebite before though (I remember it causing a disagreement in the pub) - but I’ve also heard it called a “diesel” (which elsewhere was something mixed with guinness). I’m pretty sure you sometimes got different things in different pubs in the same town.
I suppose pre-internet, we were just relying on the drunk people ordering things to decide what they wanted to call stuff (“what was that purple mixed drink called that made me throw up on my own shoes?”).
