The “good old days” of Kaliber ( ) have changed considerably. Major brands in O% alcohol (Guinness, Heineken, Kopparberg, Ghostship, etc) are, to me, indistinguishable from the real stuff.
Other outlets such as Aldi have pretty good options too - & they are cheaper than the loaded stuff!
the alcohol free wines i have tried all seem like a shloer although there was a Sav Blanc in Waitrose that I enjoyed once which was very grown up in its taste and flavour profile
