Please choose the correct ending to complete the given sentence: Food and Entertaining: [header] How to make a wine spritzer [title] Chill the wine thoroughly.

You want the liquid inside to be able to escape through the bottom so that it stays completely cool. Ending3: [substeps] You'll know that the wine is cold enough when it frosts the glass that you pour it into. [title] Pour the wine into a glass and top with club soda. Ending4: [substeps] Vintage sparkling wine might feel fizzy when it's frozen, so a chilled sparkling wine won't hold up well enough to be successful with a cocktail.
