An Italian Triple Sec from the Iseo brand of liqueurs, bottled at the rather low ABV of 15%. If you're at all interested in cocktail making, you're going to need a Triple Sec on your shelf - they add a big burst of citrus notes, which is often called for.

I bought this to make large batch margaritas for a party, it is such good value for money and people loved it, probably not the best one out there but for about £10 you really can't complain. It served it's purpose very well.
Don't buy this. It has very little flavour. Pay a bit more and get something worth drinking.
