St-Germain

Pros

• For example, a little splash of St Germain, Italicus, or even Grand Marnier can heighten this drink.
• It's why I buy St. Germain for bar programs and St. Elder for home since I can't clear even half a bottle before it goes off.
• Elderflower (St Germain) is almost universally enjoyed. I'd pick up a bottle and try it out. It's often called "bartender's ketchup" because it goes with so many things.
• .5 oz St. Germain
• One of my favorite variations is the Elder Manhattan. 3 parts bourbon, 2 parts St Germain, 1 part dry vermouth, and a dash of orange bitters.

Cons

• More delicate liqueurs can benefit from refrigeration, although often it’s not strictly necessary; this would include things like St. Germain, Chambord, cream liqueurs. ... Some liqueurs will change colour and maybe lose a little bit of...
• The difference in color and clarity between these two is amazing. Tasted side by side, fresh is sweet, floral, and light. Old tastes boozy and off.
• St.Germain is the bartender's ketchup but I dont like sweet elderflower.
• Based strictly on appearance, the St. Germain has been sitting around for a long time. I don’t think it should be that dark. Perfectly usable, but the flavor profile may have gone off some.
