Verdict: It is hard for me to recommend this.

I came to the same conclusion, £75 worse off latter and not many "decent" pints out of the 20 two packs should've gave. I had the same as you, mega fizzy to start, makes a huge mess of the fridge, doesn't really taste alcoholic or get me even tipsy after 3-4 pints (one and half pint at weatherspoons normally does me!), first few pints fizzy, last few pints look and taste of yeast, so get a couple of decent tasting possibly low-achololic pints per pack. Mine's getting packed back away into my garage or shed somewhere now. And I think you were VERY generous to give a 3 star 😉
