A Beginner’s Guide to Chardonnay Styles: Oaked vs Unoaked (Explained)

Chardonnay is one of the most widely planted grape varieties in the world, but also one of the most misunderstood. Chardonnay isn't just one style; it's a spectrum shaped by where it's grown and how it's made. And one of the biggest influences in that process is oak. 

If you've ever wondered what oaked vs unoaked Chardonnay actually means, this is a good place to start. 

Chardonnay in the Hunter Valley

Chardonnay has become an important part of the region's identity over the past few decades. Early Australian Chardonnay styles leaned heavily into oak: bold, buttery and full-bodies. Over time, winemaking has shifted towards balance and restraint, allowing fruit and acidicity to lead, with oak used more thoughtfully. This evolution reflects a broader move towards wines that are approachable and food-friendly. 

Today, Hunter Valley Chardonnay often shows:

- Ripe stone fruit flavours

- Natrual acidity for structure and freshness

- A considered use of oak, rather than dominance

What is "oaked" Chardonnay? 

After fermentation, the wine is aged in oak barrels. And this is where Chardonnay really starts to take on a different personailty. 

Oak influences a wine in two key ways:

1. Flavour: Oak can introduce subltle notes like: Vanilla, spice, toasted nuts, light caramel or butter. These don't overpower the wine when used well, they sit alongside the fruit, adding depht. 

2. Texture: Oak barrels allow tiny amounts of oxygen into the wine over time. This softens the structure and gives Chardonnay that round, creamy mouthfeel. It's less sharp, more layered and often lingers a little longer on the palate. 

That being said, not all oak is the same.

Even within “oaked Chardonnay”, there’s a lot of nuance. Winemakers make decisions around:

- New vs older barrels (new oak = more flavour, older oak = more subtle influence)

- French vs American oak (French tends to be finer and more restrained)

- Time in barrel (months vs longer ageing)

At Tulloch, we lean toward a more considered use of French oak, allowing it to support the wine rather than dominate it.

What is "unoaked" Chardonnay? 

Unoaked chardonnay is all about clarity and freshness. Instead of being matured in oak, the wine is fermented and stored in stainless steel or neutral vessels. 

Typical characteristics:

- Citrust, green apple and light stone fruit

- Crispy acidity

- Lighter body

- No buttery or vanilla notes

It's a style that highlights the grape itself, without the influences from oak. 

So, which Chardonnay style is best?

There’s no single answer! It depends on what you enjoy.

- Choose a lighter, restrained style for freshness and easy drinking

- Choose a fuller, oaked style for richness and complexity

- Or explore both styles side by side to better understand the difference.
