We have this beverage additive since the summer of 2012 at the Spar subscription and are completely satisfied. Although the taste can not serve up a branded product, but also may be caused by sweetener. In my opinion, always taste it a little out of the sweetener, which also leads to a slight aftertaste.
When handling is important in the filling of the syrup that the drink excessively foamed, otherwise it is a medium-sized carpentry.
I would still want to get a details on durability of the syrup after opening the bottle.
