I use whatever beer or lager is cheapest!, I used to use Asda Bitter which were 4 for about £1.50 but they’ve not had any recently. This week I got 18 tins of Carlsberg for £11 and 4 bottles of Schweppes for £1.30 a bottle at Tesco.
I buy the cheap Asda bitter for shandy, bitter shandy is nicer than lager shandy. But I do notice the cheap Asda stuff gives me a headache.
