Yay! We love punch. Especially in summer, it should definitely be topped off with an excellent sparkling wine. In this case: It’s best to opt for a high quality wine because a punch is always only as good as its ingredients. The sparkling wine should, however, be added to the fruit/wine mix shortly before serving, so that the refreshing bubbles are not lost. And don’t stir for long. For larger quantities, it’s preferable to top the mixture up again with sparkling wine.
