Drinking too much alcohol does affect your blood pressure, especially if you are a chronic heavy drinker. I know 2 drinks does not seem "heavy", but studies show that drinking 1 ½ to 2 drinks per day increases your risk of high blood pressure. Drinking two glasses of wine nightly also interferes with the effectiveness of any high blood pressure medications or treatments you may be using to control your high blood pressure.
Alcohol also stimulates the release of cortisol (a hormone). Cortisol promotes sodium retention and increases potassium losses, both of which can blood pressure to increase.
I recommend cutting back to at least 1 glass per day or less. One glass equaling 10 ounces. Consider red wine due to its link with some heart benefits.

I want to correct a line in my answer to you. One glass of wine is equal to 4 ounces and provides 10 grams of alcohol. To minimize the affect on your blood pressure, it's best to consume no more than 4 ounces of wine daily.
