Syrah Vs. Shiraz

Home Wine Making Blog: "This is a story of two wines, Syrah and Shiraz, and how they both are the same, yet different, at the same time. On the surface it seems to be somewhat of an exercise in semantics, with their names being the only difference, but after taking a closer look it starts to become clear that there is much more to the story than just that.

Syrah and Shiraz teaches us a lesson, one that illustrates how a grape's environment and the way in which it is process can influence the outcome of a resulting wine.

Any wine expert will tell you that Syrah and Shiraz are two varietal wines that are made from the exact same grape. If you analyze the DNA of each of the grapes used to make these wines you will find that there is no difference between them.

Then Why The Two Names?

The French refer to the grape and the wine they make from it as Syrah. Other parts of the world such as: South America, Australia, New Zealand, Canada and parts of the United States refer to the grape and the wine as Shiraz.

But there is something more than just a difference in name. There is a difference in style as well. While both wines are very assertive, a Syrah tends to be a little more elegant and complex. It usually has more of a smokey, earthy character with flavors of plum and spicy pepper. A Shiraz on the other hand is more crisp and fruity, less layered with slight, jammy flavors of berry as compared to a Syrah. This is a very wide generalization of each wine, but even so it would be safe to say that if you tasted both wines side-by-side you would notice more differences than similarities between the two.

So, Why Are These Wines Different?

While the grape remains the same in each wine there is so much else that is different. The soil, the climate, the cultivation, and the fermentation all vary to make a Syrah a Syrah and a Shiraz a Shiraz.

While different soils can not assert there own character onto a grape, they can guide the way in which a grape develops its own flavor. This is referred to as the terroir. The French vineyards are heavy in limestone which can hold moisture better and deeper than most soils. This forces the vines to get more of their nutrients from deeper soils. The result is a wine with more layered, complex flavors.

The French are not allowed to use irrigation or fertilization on their vines either. This stems from governmental laws designed to keep the grape production limited. This leads to stressed vines with fewer berries, but with each berry packing more flavor.

This is all in contrast to places like Australia, South Africa and New Zealand where Shiraz grapes are produced in sandy soils with plenty of fertilization and irrigation. The cultivation is abundant. This creates a wine with a more even character than a Syrah and with the ability to mature more quickly.

The Syrah is also grown in France's cooler climate. This lends to the plum-like, smokey character of this wine. This is in comparison to Shiraz which is grown in warmer climates which makes the wine more jammy and berry-like.

Even the rate of fermentation plays some role in the flavor development of the wine. A Syrah is fermented more slowly so as to increase the time the pulp can stay on the fermentation. A Shiraz is fermented at a faster, more-normal rate which helps to make the wine, in general, more fruity.

In Summary:

So as you can see there is much more than just the grape when it comes to bringing a wine to life. While a wine's character always begins with the grape. It ends upon many other factors, including the human touch. There are many other examples of how this is true, but none quite as clear as the dichotomy of the Syrah/Shiraz grape. It's a clear example of how the New World wines compare with the wines of the Old World."

One of my readers asked me how you could make a white wine out of red grapes (i.e. he was given a "white Merlot" for Christmas that tasted more like a Chardonnay) and he suggested that it was most likely due to removing the grape skins.

I thought it was a great question so thought I would include my response as a follow comment to this article.

"Great question.

You are correct, the colour of wine comes from the skins. If you take a red grape and a green grape and cut them open you'll note that the fruit on the inside is basically the same colour.

If you remove the skin on both grapes and crush them you will note that the resulting juice is either colourless or golden in colour. If you are using a red or black grape and you want to add some colour to the juice then let the juice come in contact with the skin. The longer the contact time, the deeper the colour.

To make a blush (aka rose) then only allow the skins to come in contact for a short period of time. For a deeper red, let the skins stay in contact with the juice for a longer period of time.

A really good example of how the colour of the wine doesn't match the colour of the grape skin is champagne.

A decent amount of the tannin (acidic taste) will come from the skin so this is probably why your white Merlot tasted more like a Chardonnay.

Make sense?"
