Should you choose to stir this lovely wine cocktail rather than shake it, reach for the wine bottle first. According to the wise folks at St-Germain, this will assist in your cocktail-making endeavor, because the liqueur is denser and will sink and meld with the wine, making your job quite an easy one. Their online cocktail-making tutorial continues to explain that “If you pour the St-Germain first, it will tend to sit under the wine rather than mix, which the wine may find rather rude, especially if it’s a good vintage.”
