And making the second one with limoncello instead of lemon juice and sugar changes it completely, but makes it just a nice - and probably much more alcoholic

Made exactly as specified. It tastes like nothing so much as ice-cold Lemsip (although I usually fortify Lemsip with a good slug of Scotch). But it's rather nice.

Thanks for the definitions. Can you tell us why you still have to be age-checked to buy alcohol-free drinks in the UK? I’m in my 60s so it’s no skin off my nose but if alcohol-free beer is only as intoxicating as Coca-Cola I’d have thought teenagers ought to be allowed to buy it!

Ah, now that’s a great idea.
