Here are 2 white wines and 2 red wines to look for. They are very reasonable priced, often $5 or $6 a bottle.
Gato Vinho Verde is a light wine citrine in color, a fresh flavor
of lemon and peaches with a slight effervescence. I usually comes in a flask shaped
Gazela Vinho Verde is a dry wine with a crisp aroma, slightly
with green grape acidity. It's like a lighter version of the French
Reguengos has blackberry flavors, is rich and medium bodied. It's
dry and makes a good quaffing wine.
Vinha Nova is a smooth fruity wine with grape flavors and has a
merlot/gamay taste. It's a good wine to serve with grilled, garlicky foods.
