I have never been interested in low alcohol beer, but recently I became intrigued at the idea of Guinness 0%, so I bought a 4 pack in my local Tesco, and have to say it looked and tasted very similar to the real thing, but the head disappeared quickly. I won't buy it again as my curiosity has been sated, but its really not bad.
Bit off a faff, but here's a trick I learnt during the first lockdown, when I was buying 2 litre bottles of draught from the window of a local pub: pour a little beer into the bottom of the pint glass, stick a hand blender in and whizz it for 10s, add the rest of the beer. Perfect head that stays there like you'd expect.
