A easy way to determine how much body a wine has is to think about the weight of it on your tongue. Here’s my favorite example using milk.
For full body wines think of heavy cream. For reds these include Shiraz/Syrah, Zinfandel, California Cabs and Chardonnay, Viognier.
For medium body wines think whole milk. These include Merlot, some California Pinot Noirs, Malbec, Pinot Gris, Pinot Grigio, French Chardonnay.
For light body wines think of 2% milk. These include Pinot Noir, Rosé, Sauvignon Blanc.
To be clear these are just examples of styles that generally fit into the categories. Wines has a lot to do with where it’s grown, usually if it’s hot it will be fuller and if it’s cold, it will be leaner. To make it simple without tasting it check the alcohol level. Anything over 13.5 is considered full bodied. Got it?
