I drink quite a few low/no alcohol drinks. There are so many now! I've not found a decent red though I'm afraid
Lullabelle. I like the McGuigans white and fizz. M&S do two nice bottles of fizz. Ones called Fizzero. Can't remember the other. The easiest to find in shops in Nosecco ( I was not so keen.)
For 'gin' type drinks Seedlip do three. I liked the spice one best. Even Gordon's do one, but not tried it.
Oh, and Martini do a nice non alcoholic version of Rosso. Rochester ginger (healthfood shops) for a ginger wine alternative.
Beers, larger etc.? There's loads now. Even Guinness have a zero version. My favourites are Doombar and Ghostship, and for lighter beer/larger Becks/Bud/Heineken.
Eta. I've found Sainsburys has a relatively small selection compared to Morrisons/Tesco. Not sure about Asda.
