SodaStream Diet Ginger Ale Syrup, 14.8 fl. oz.

It works as a fizzy drink flavor, but if you use the recommended amount it seems very weak to me. It's not much like the flavor of the two big brand name colas. My biggest problem? The very high price of the various syrups sold for use with domestic fizzy drink machines. Having worked in a couple of bars as a young person I know cola and other syrup is cheap, but this stuff is quite the opposite. It's also watered down compared to the syrups the bars used to receive from Coke & Pepsi (although it's quite possible the big names are watering down their commercial supply of syrups as well, I suppose). Anyway, as long you remember to fizz your water BEFORE adding the syrup (you'll have cleaning to do if you do it the other way round...) and as long as you don't mind using roughly two capfuls of syrup per liter bottle of water, it makes a decent cola drink. I keep one bottle in stock just in case I need a hit of cola-like flavor, but mostly I just drink icy cold plain fizzy water.
