White wines pair well with corn chowder, specifically Chardonnay, but depending on the ingredients in the chowder a red wine may work too. Chardonnay has a slightly sweet, buttery flavor that seems to work well with any corn dish. However, corn chowder that includes smoky ingredients such as smoked bacon or ham may work with a red wine.
Chardonnay is the base for many different types of champagne, so serving champagne with corn chowder is another option. Remember that foods can bring out the flavors of wine and vice versa, so choosing a complementary wine will enhance both food and drink.
