Content of Alcohol seems to be a regular worry by light drinkers or people wanting to try Wine for first time (-well there is always a second time).
Just like Beer, Wine is also categorized from being lightest to the strongest. Furthermore, The Alcohol content in wine ranges wildly from a low concentration of 5.5% to 23% ABV (Alcohol By Volume). Some factors that affect the alcohol concentration in the wine are the style of wine, quality of wine, and climate where the fruit (well mainly grapes) grow.

alcohol content in wine

Alcohol Content in different Wines

General Wines 8-14%
Sparkling Wine 8–12%
Table Wine 9–14%
Retsina 10-11%
Dry White 10-12%
Cabernet 11-14%
Barley Wine 11–15%

Red Wine usually comes under category of Medium Alcohol Wines, which usually (I am using this word more than usually) have a Alcohol Concentration of 11.5%–13.5% ABV.

Folks from US and perhaps even EU might believe the percent-content to be a little low, but for the rest of the world 11.5%–13.5% ABV is the average. In fact, the US standard serving of wine is a glass (5 oz) of medium alcohol-content wine. Most European wines will be in this range, as well as dry American bargain wines.

Indian Red Wines also come in a few types like Tables Wines, Sparkling Wines, Sweet Red Wines, etc. So check the Alcohol concentration in your Red Wine, since it can large vary.
I have seen many people ask about Heritage Red Wine's Alcohol Content (a popular and cheap option in India). Well, it can vary from 8% (Heritage Sparkling Wine - twisty) to 14% (Heritage Table Red Wine - Cabernet).

Red Wines are seeing a increase in liking by young people, specially women in India, amidst India's growing consumption of liquor.

ALWAYS check the Alcohol content/concentration when you buy your Wine.
Don't assume anything

Do you know about the Myth "Keep your Wines at room temperature" ?
Well, don't believe every Myth you hear. The room temperature for Wines refer to room temperature in Europe which is usually 16-18°C.
So unless you live somewhere with below 20C being room temperature, go and put your Wine in Fridge, to not ruin it.

Wines must always be stored under strict temperature control and ideally be at a constant 14-16°C. Taste of your wine can get affected by factors like inadequate humidity (for bottles closed with a cork), exposure to sunlight, etc.

Since a constant room temperature of 14-16°C is not possible at most places in India (six major climatic subtypes duh), it is advisable to store it in the fridge rather than keeping it at room temperature.

how much alcohol in wine

How much wine should you be drinking?

How much can you handle ?
The general rule of thumb is that a glass of wine is just like any standard Alcohol drink. On average women take one glass a night and men take two, given that you CAN handle a glass with standard alcohol concentration. However, this makes the assumption that the wine has standard Alcohol content of only 12% ABV. So if you’re drinking a high-alcohol-concentration wine like Port or Thunderbird (20% ABV !!), the recommended serving size is about half.

Its usually better to get a lower alcohol wine, especially if you love to drink.
You can drink more light-alcohol wine with the same effect as one glass of high-alcohol wine. Ingenius.
