If you've ever enjoyed a glass of Shiraz and wondered what you're actually taking in, you're asking a very reasonable question. Calories in a glass of red wine aren't always obvious — there's no nutrition panel on the side of the bottle, and the answer varies more than most people expect.
Here's a clear, no-nonsense breakdown of the numbers, what drives them, and how to make sense of it all.
Calories in a Standard Glass of Red Wine, by Variety
A standard 150ml glass of red wine contains roughly 120–140 calories, depending on the style. For context, that's broadly similar to a small chocolate bar or a glass of full-cream milk.
Here's a quick guide by variety (per 150ml glass):
- Pinot Noir (12–13% ABV): ~120–125 calories
- Merlot (13–13.5% ABV): ~125–130 calories
- Cabernet Sauvignon (13.5–14.5% ABV): ~125–135 calories
- Shiraz (13.5–15% ABV): ~130–140 calories
- Port / fortified red (18–20% ABV): ~160–180 calories
These are approximate figures based on a dry wine at a standard pour. Your actual count will shift depending on pour size and alcohol content — more on both below.
What About the Calories in a Bottle of Red Wine?
A standard 750ml bottle gives you roughly five glasses (for more on how pour sizes work, see our guide to how many glasses of wine are in a bottle). Multiply the per-glass figure by five and you get a rough total:
- Lighter reds (Pinot Noir, Gamay): ~600–625 calories in a bottle of red wine
- Medium-bodied reds (Merlot, Grenache): ~625–650 calories
- Full-bodied reds (Shiraz, Cabernet Sauvignon): ~650–700 calories
- Fortified reds (Port): ~800+ calories per bottle
The spread across a whole bottle is wider than most people realise, simply because higher-alcohol wines pack significantly more energy per glass.
What Actually Makes Red Wine High in Calories?
Most of the calories in red wine come from just two things — alcohol and sugar. And for most dry reds, it's almost entirely the first one. Here’s a closer look:
1. Alcohol (the main driver)
Alcohol delivers around 7 calories per gram, more than carbohydrates or protein, and just under fat. So the higher the ABV, the higher the calorie count. An Australian Shiraz sitting at 14.5% will have noticeably more calories than a lighter French Pinot Noir at 12.5%, even in the same 150ml pour.
2. Residual sugar (a secondary factor for most reds)
Most red wines are fermented to dryness, meaning very little sugar remains. A dry red typically has just 1–2 grams of sugar per glass — a minimal contribution to the total. Where sugar becomes more relevant is in sweet red wines, fortified styles like Port, or any wine labelled "off-dry." These carry higher red wine sugar content and noticeably more calories as a result.
Does the Variety Make a Big Difference?
Yes, but not as dramatically as you might expect between standard dry reds. The real lever is alcohol content, and that varies more by style and producer than by grape variety alone.
As a rule of thumb:
- Lower alcohol reds (11.5–12.5% ABV) — lighter styles, fewer calories in red wine per glass
- Mid-range reds (13–13.5% ABV) — the sweet spot for most everyday drinking
- Higher alcohol reds (14–15%+ ABV) — bold, full-bodied styles with the highest calorie counts
Australian reds, particularly Barossa Shiraz and many Cabernet Sauvignons from warm-climate regions, often sit at the higher end of the ABV range. This is a reflection of the warm growing conditions that produce riper, more concentrated fruit and more alcohol.

The Pour Size Problem
Here's where most people underestimate their intake: pour size. The standard glass of red wine in Australia is 150ml, but a typical large wine glass can hold 400–500ml. Without measuring, it's easy to pour two servings and count them as one.
A quick reference:
- 125ml (small glass): ~100–105 calories
- 150ml (standard): ~120–140 calories
- 175ml (medium): ~145–165 calories
- 250ml (large/generous home pour): ~200–230 calories
If you're keeping an eye on your intake, the pour matters as much as the variety.
How Does Red Wine Compare to Other Drinks?
Calories in red wine are often competitive with other popular choices:
- Standard beer (375ml, ~4.5% ABV): ~145–150 calories
- Glass of red wine (150ml): ~120–140 calories
- Glass of white wine (150ml): ~110–125 calories
- Spirits (30ml, neat): ~65–70 calories
- Gin & tonic (30ml gin + 150ml tonic): ~130–145 calories
So red wine sits in the middle of the pack. It's not a low-calorie drink by any measure, but it's not the highest-calorie option at the table either.
Tips for Calorie-Conscious Wine Drinkers
You don't need to give up the wines you love. A few practical adjustments make a real difference:
- Choose lower-ABV reds. Wines around 12–13% ABV have meaningfully fewer calories than those at 14.5%+. Check the label before you buy.
- Stick to a standard pour. The 150ml restaurant measure is a useful benchmark. At home, consider using a measure jug once — it's eye-opening.
- Favour dry over sweet styles. Dry reds have minimal residual sugar. Fortified wines and sweet reds carry more calories.
- Drink slowly and with food. This naturally reduces how much you consume in a sitting and helps your body process alcohol more efficiently.
Frequently Asked Questions
How many calories in a glass of red wine?
A standard 150ml glass of dry red wine contains around 120–140 calories, depending on the wine's alcohol content. Lighter reds like Pinot Noir sit at the lower end; bold, higher-alcohol styles like Shiraz or Cabernet Sauvignon sit higher.
How many calories are in a bottle of red wine?
A standard 750ml bottle of dry red wine typically contains 600–700 calories. Lighter styles come in closer to 600; fuller-bodied or higher-alcohol reds push toward 700 or beyond.
Is red wine high in calories compared to other alcohol?
A glass of red wine has fewer calories than a standard beer or a spirit-based cocktail with a mixer, but more than a straight spirit. The main driver is alcohol content — the higher the ABV, the more calories.
Which red wine has the fewest calories?
Generally, Pinot Noir and other lighter-bodied, lower-alcohol reds are the lowest-calorie option among dry red wines. Wines from cooler climates (Tasmania, Burgundy, the Yarra Valley) tend to have lower ABV and therefore fewer calories.
Does red wine have a lot of sugar?
Most dry red wines contain very little sugar, typically 1–2 grams per glass. Red wine sugar content becomes more significant in fortified styles like Port, or wines labelled off-dry or sweet. For everyday dry reds, sugar isn't the main calorie concern, alcohol is.
How many calories in red wine vs white wine?
White wines are generally slightly lower in calories than reds, primarily because many white varieties are produced at lower alcohol levels. A glass of Sauvignon Blanc or Pinot Grigio typically contains 110–120 calories, compared to 120–140 for most reds. The gap is modest, style and ABV matter more than colour.
The Bottom Line
Knowing the numbers is useful, but it doesn't have to complicate your enjoyment. Choose a style you love, pour a sensible measure, and drink it with food. That's pretty much the whole strategy. Explore our full range of red wines and all wines at The Wine Collective.
