Use red, blue, yellow, pink, or any shade of decorative sugar to add a pop of color to an otherwise beige drink. Dip the rim of the glass in a tray of shallow water, then immediately place the top of the glass, upside down, into another shallow plate of colored sugar.
When serving glasses at a large event, such as a graduation party or engagement soiree, it's nice to break up the monotony with rows of various-hued sugar rims. For even more effect, stir in raspberry puree or vibrant pomegranate arils. What's your way of livening up an ordinary glass of sparkling wine?
