Grenadine

Grenadine is a common non-alcoholic pomegranate syrup with a characteristic deep red colour. It is a very popular cocktail ingredient, used for its pomegranate flavour and more for its ability to add a reddish to pink tint to a cocktail.

The name Grenadine originates from the French for pomegranate, which is grenade.

Grenadine is not subjected to regulations like alcoholic beverages are, and there are no region specific formulae any more, and thus manufacturers often replace pomegranate with blackcurrant juice and other fruit juices while retaining the same flavour profile.

Many producers now use artificial ingredients like high fructose corn syrup, water, citric acid, sodium citrate, sodium benzoate and food grade red colour along with natural and artificial flavours.

Heron began with good-quality bourbon and would add: An inch [2.5 cm] of vanilla bean, about a quarter of a lemon, half of a cinnamon stick, four cloves, a few cherries, and an orange bit or two. He would let this soak for days. And right when he was ready to finish, he would add his sweetener: he liked to use honey. - Wikipedia

In the United States, Southern Comfort is available as 42 US proof (21% ABV), 70 US proof (35% ABV), 100 US proof (50% ABV), and 60 US proof (30% ABV) in Australia.
