(BusinessInsider) - Even occasional wine drinkers have a preference when it comes to red or white wines. But have you ever wondered how your state’s drinking habits stack up to, say, California or New York?

Well, NakedWines.com, a popular online wine merchant, has done the math for you. According to the maps below, middle America leads in white wine consumption, while the east and west coasts prefer red. NakedWines compiled this data based on its sales during the first six months of 2014, which made for a sample of over one million bottles of wine. The company also crunched the numbers on specific varietals and domestic versus imported wines.

Here's a closer look at the data.

California is the top wine-buying state.

California, New York, Florida, Colorado, and Texas are the top five wine-buying states. (Legal issues prevent NakedWines from shipping to states in white.) Note the total number of bottles purchased below each percentage.

The middle states like white wines.

The dark blue states in the center of the country indicate a strong preference for white wines, specifically sauvignon blanc, according to NakedWines.

The coasts prefer red.

Michigan, Pennsylvania, North Carolina, and Mississippi are heavy red states (at least when it comes to wine). Michigan and Mississippi are two of the biggest purchasers of cabernet sauvignon.

New Yorkers enjoy domestic bottles.

Iowa, Kansas, New York, and Maine have the highest domestic wine buying power, while Texas has the least. It's interesting that California ranks near the middle on this map, considering the scope of its wine-making industry.

Texas is a big fan of French wines.
