TL;DR
Shiraz and Merlot are both dry reds. Shiraz usually has firmer tannin and smells of blackberry and black pepper, from a compound called rotundone in its skins. Merlot is softer and smells of plum and black cherry. Climate moves both: cool sites give more pepper and grip, warm sites riper fruit and softer tannin.
The Shiraz vs Merlot choice comes down to one sip: Shiraz brings black pepper and a firmer grip, Merlot brings plum and a softer one. The region on the label tells you how far each grape leans that way, and in a few places the two nearly swap.
Shiraz vs Merlot, in One Paragraph
Shiraz and Merlot are both dry reds. Shiraz usually has more tannin (the drying grip on your gums) and smells of blackberry and black pepper. Merlot is softer and smells of plum and black cherry. Both make medium to full body (weight in the mouth: skimmed versus whole milk). The pepper in Shiraz comes from rotundone, a compound in its skins that 20 to 25% of people cannot smell. Shiraz and Syrah are the same grape. Merlot ripens early and leads the blends of Pomerol and Saint-Émilion. Cool sites give both grapes more grip, warm ones riper fruit and softer tannin.
Shiraz vs Merlot Side by Side: Which Style to Pick
Pick by the region on the label, because each grape changes with climate. A cool climate (mild summers, slow ripening) gives tarter, lighter wine; a warm one gives riper and stronger wine.
| Style | Label clues | Body and tannin | Smells of | Pick it for |
|---|---|---|---|---|
| Cool-climate Syrah | Northern Rhône, Margaret River, the word Syrah | Medium to full body, medium-plus to high tannin | Cracked black pepper, then blackberry | Pepper-crusted steak, lamb, a red with grip |
| Warm-climate Shiraz | Barossa, McLaren Vale, the word Shiraz | Full body, softer tannin | Jammy blackberry, chocolate, pepper in the background | Barbecue, burgers, a ripe red on its own |
| Bordeaux-style Merlot | Pomerol, Saint-Émilion, other Right Bank names | Medium body, fresher acidity, firm backbone | Strawberry, red berries, a leafy edge | Tomato pasta, pizza, roast chicken, mushroom dishes |
| International-style Merlot | California, Chile, Australia | Full body, velvety tannin | Black plum, black cherry, fruitcake when very ripe | Roast meats, an easy weeknight red |
If the label names a cool place, expect pepper first and tannin you can feel. If it names a hot one, expect ripe fruit first and a softer finish. A Barossa Shiraz and a ripe California Merlot can weigh almost the same, while a northern Rhône Syrah grips far harder than either.

One question on what you just read
Which bottle is most likely to smell most strongly of black pepper?
Tap an answer to see how you did.
Is Merlot Sweeter Than Shiraz?
No. Both are almost always made dry (no sugar you can taste; fruity is not sweet). Merlot only seems sweeter because soft tannin and ripe plum read as sweetness. Ripe fruit is a smell, not sugar. Tannin works the other way: its grip makes a firm Syrah taste drier than a Merlot with the same zero sugar.
Very ripe Shiraz plays the same trick with its jammy blackberry. For the full difference between fruit and sugar, see sweet vs dry wine.
Why Does Shiraz Taste Peppery?
Shiraz smells of black pepper because of rotundone, the same aromatic compound found in peppercorns, which builds up in the grape skins. The Australian Wine Research Institute announced the find in 2007. It shows most clearly in cool climates, so a northern Rhône Syrah smells more of cracked pepper than a Barossa Shiraz.
Merlot has no such signature. Its spice, when there is any, usually comes from oak barrels as vanilla or clove. About 20 to 25% of people cannot smell rotundone at all, so two people can argue over the same glass and both be right. The spicy red wines guide lists the other grapes that carry it.
Which Has More Tannin, Shiraz or Merlot?
Shiraz usually has more. Syrah from cooler places such as the northern Rhône has medium-plus to high tannin, while Merlot is known for medium tannin. Two exceptions narrow the gap. In hot regions Syrah turns fuller, softer and jammier. In Pomerol, on Bordeaux's Right Bank, iron-clay soils give Merlot a firmer tannic backbone than it shows elsewhere.
Harvest timing matters as much as soil. Many New World producers pick Merlot late, which gives inky, full-bodied wine with high alcohol and velvety tannin. Picked earlier, as in Bordeaux, it keeps more acidity and stays medium-bodied. Our guide to tannins explains why skins and ripeness change the grip.
Is Shiraz the Same Grape as Syrah?
Yes. Shiraz and Syrah are one grape; Shiraz is the name used mainly in Australia. Its home is the northern Rhône in France, where it is the only red grape, and its parents are two old grapes from southeastern France, Dureza and Mondeuse Blanche.
Producers in cooler places tend to write Syrah on the label, so the word hints at a peppery, firmer style. Syrah vs Shiraz shows how far that rule holds.
Which Goes Better With Steak, Pasta or Pizza?
Shiraz goes with charred, peppery and fatty meat; Merlot goes with tomato pasta, pizza and roasts that need less grip. The rule comes from the plate. Fat softens tannin, so a firm wine needs fatty meat. Tomato is acidic, so it wants a red with fresh acidity and moderate tannin rather than a drying one.
- Pepper-crusted or charred steak: cool-climate Syrah. The pepper on the crust meets the pepper in the wine, and the fat tames its tannin. More cuts in wine with steak.
- Burgers and barbecue: warm-climate Shiraz. Sweet, smoky sauce wants ripe fruit, and the grease handles the tannin.
- Lamb with herbs: either, by weight. A pink rack takes Syrah; a slow-roast shoulder suits Right Bank Merlot. See wine with lamb.
- Tomato pasta and pizza: Bordeaux-style Merlot. Its fresher acidity keeps up with the sauce, where a ripe, low-acid Merlot tastes flat, as wine with pizza explains.
- Mushrooms and roast chicken: Bordeaux-style Merlot, whose fresher acidity and plum suit savoury, earthy food.
If the dish carries chilli heat, choose the lower-alcohol bottle of the two, because alcohol makes the burn stronger.
Where Do Shiraz and Merlot Grow Best?
Merlot does best in cooler Bordeaux, where it ripens early; Shiraz follows its climate wherever it grows. Merlot ripens up to two weeks before Cabernet Sauvignon, so it reaches ripe plum in places where Cabernet struggles. It makes up most of the blend in Pomerol and Saint-Émilion, two Right Bank names covered in the Bordeaux wine guide.
With about 266,000 hectares planted worldwide in 2015, Merlot turns up on almost every shop shelf in both styles. If the bottle comes from a warm New World region, expect the riper, softer one.
Shiraz follows its climate in Australia too. Cooler Margaret River makes Shiraz with slightly less alcohol, often in a more French style, while the warm Barossa gives the full, jammy version. The Australian wine guide maps both.
Which Is Better for Beginners?
Start with Merlot if tannin dries your mouth out; start with Shiraz if you already like peppery or smoky food. Merlot's softer grip makes plum easy to pick out on a first taste, and a Pomerol shows the same grape at its most serious. The Merlot wine guide and best wine for beginners suggest the next steps.

Frequently Asked Questions
Is Shiraz or Merlot sweeter?
Neither, in most bottles. Both are normally fermented dry, so there is no sugar you can taste. Merlot often seems sweeter because its tannin is softer and it smells of ripe plum and black cherry, and the brain reads ripe fruit as sweetness. Very ripe, warm-climate Shiraz can give the same impression with its jammy blackberry. If a red is made to taste sweet, the label usually says so.
Which has more tannin, Shiraz or Merlot?
Shiraz usually does. Cool-climate Syrah from places like the northern Rhône has medium-plus to high tannin, while Merlot is known for medium tannin that ripe New World styles make velvety. The gap narrows in hot regions, where Shiraz turns softer and jammier, and in Pomerol, on Bordeaux's Right Bank, where iron-clay soils give Merlot a firmer backbone.
Is Shiraz the same as Syrah?
Yes. Shiraz and Syrah are the same grape, a cross of two old French varieties, Dureza and Mondeuse Blanche. Shiraz is the name used mainly in Australia, Syrah the name used in France and many cooler places. The label word often hints at style: Syrah tends toward pepper and grip, Shiraz toward riper fruit, though both names appear on both styles.
Which is better with steak, Shiraz or Merlot?
Shiraz, for most steaks. A charred or pepper-crusted steak has fat for tannin to grip and pepper that a cool-climate Syrah repeats. Merlot suits leaner cuts, roast meats and steaks with mushroom or red-wine sauces, where a firmer wine would taste harsh. If the steak carries chilli heat, choose the bottle with the lower alcohol of the two.
Why does Shiraz taste peppery?
Shiraz smells of black pepper because of rotundone, the same aromatic compound found in peppercorns. It builds up in the grape skins and shows most clearly in wines from cool climates. About 20 to 25% of people cannot smell rotundone at all, so the same glass can seem peppery to one person and plain blackberry to the next.
Which is better for beginners, Shiraz or Merlot?
Merlot is the easier first step if tannin makes your mouth feel dry, because its grip is softer and its plum fruit is easy to spot. Shiraz suits beginners who already like peppery or smoky food. The quickest way to learn both is to taste them side by side and note which one dries your gums more.
