Sparkling water is one of those things that will eventually win you over. Once you get the bug, you have a hard time going back to still. But unless you stock the fridge with bottles or get a gadget that carbonates beverages, like a Sodastream, you're pretty much stuck with boring old still when you're home. Knowing that the agua struggle is real, the GROHE Blue water system solves the problem by delivering carbonated water right through your kitchen faucet.
