The make-your-own fizzy-drink machine, which seemed to die a death in the early 90s, is presumably hoping that it can be the Nespresso for the soft-drink lover.
Yet where Nespresso offers you an easier way to make great coffee, SodaStream's proposition seems less clear. Its subdued UK website gives consumers five reasons to purchase: fresher taste, customisable flavours, lower sugar, environmental credentials, and a supply that never runs out.
Unfortunately, none of these stand up to much scrutiny. Maybe it's just me, but I don't find myself salivating at the prospect of designing my own cola and raspberry flavour.
I also wonder about the truth of the environmental claims, given that the machine uses a cylinder that must be exchanged regularly.
There might be a place for this in the kitchen of carbonate addicts who fear ever running out, and for families who think it's more fun for the kids to make their own, but I don't think Coke will be trembling in its boots.
