Need to know

  • Eight experts taste tested 44 different types of butter
  • The butter was split into three categories: unsalted, salted and cultured 
  • Australian-made butters had some serious competition

Butter is made from essentially just one ingredient – cream – so you'd be forgiven for thinking that all butter must taste the same. But its flavour and texture can differ depending on whether it's salted, salt reduced or unsalted, how well it's blended, whether it's cultured or not, where it's from and what the cows feed on, among other things. 

So which butter tastes best? We blind tasted and reviewed 44 butters, from brands including Devondale, Lurpak, Mainland, Pepe Saya and Western Star, to find out which is the cream of the crop.

We categorised the butter into three groups: unsalted, salted and cultured. 

Boasting a "rich golden colour" and "unique creamy flavour and smooth mouthfeel", Westgold's Unsalted New Zealand Grass-fed Butter scored the highest in the unsalted butter category with a CHOICE Expert Rating of 75%. 

The highest-scoring salted butters were Kerrygold Pure Irish Salted Butter (with a CHOICE Expert Rating of 79%) and Lurpak's Slightly Salted Butter (76%). The Kerrygold salted product was also the best performing butter overall in our taste test.

As for the cultured category, Tasmania took out the top prize with its Meander Valley Salted Cultured Butter scoring 76%. However, at $3.08 per 100g, it's on the more expensive side compared with the top performers in the other categories (Westgold Unsalted New Zealand Grass-fed Butter is $1.25 per 100g and Kerrygold Pure Irish Salted Butter is $2.40 per 100g). 

Here are the top performing butters in our test, listed by category.

What is butter made of?

Butter is nothing more than cream, with salt sometimes added. So how does it go from cream to butter?

In 'On Food and Cooking: The Science and Lore of the Kitchen', sometimes referred to as 'the chef's bible', author Harold McGee describes making butter as a simple but laborious task created by agitating a container of cream until the fat globules are damaged and the fat leaks out and sticks together in masses large enough to gather. These solids form the butter, and what is left over is buttermilk.

It may seem like there's not much to the taste of butter – which is essentially milk fat – but there are many factors that impact the flavour of the milk that makes the cream that then goes on to make the butter. The season, the environment, the cow's breed, its feed and the processing all make a difference to the flavour of the milk. 

As for the colour of butter, the amount of grass in a cow's diet plays a role here. Grass gives the milk a yellow pigment, so cows that have less grass in their diet often produce a paler butter.

What is cultured butter?

Cultured butter is when the cream used to make the butter is slightly soured by adding lactic acid bacteria before or after it's churned. This is common practice in Europe and the flavour has been described as a bit more sour and fuller than non-cultured butter.

When categorising butters for this test, we only included butters in the cultured category that specified 'cultured' on the front of the pack.

Is Australian butter good?

There seems to be an assumption that European butter, in particular French butter, is the best in the world. This may be because European butter usually has added cultures and often a higher fat content, which is believed to contribute to a better flavour and texture.

In our butter taste test, first and equal-second place went to European butters (from Ireland and Denmark), while an Australian product tied for second and a New Zealand product came third.   

The one salted French butter that we taste-tested, President French-Made Salted Butter, was in the top 10 of results overall, but the President French-Made Unsalted Butter received the lowest score in its category with 59%. 

Admittedly, we only tested two French-made products compared to the 29 Australian butters tested, but perhaps we can still conclude that Australian butter can be very good.

The science of butter

The connection between milk fat and taste

In Australia, butter must comprise at least 80% milk fat. Some say that the higher the milk fat percentage, the richer the butter tastes. However, we didn't see a correlation between milk fat percentage and our taste test results.

For example, the product with the highest percentage of milk fat in our test, Meander Valley Cultured Salted Butter (86.6% milk fat), was in the top three scorers for taste alone (that is, not factoring in the nutrition component that makes up the overall score).

But the products with the next highest percentage of milk fat after Meander Valley (Coles Organic Unsalted Butter with 84.7% milk fat and Remarkable Milk Company True Organic Butter Unsalted with 84.6% milk fat) hovered around the middle of the list in terms of their taste performance.

The butter with the equal-lowest percentage of milk fat – Kerrygold Pure Irish Salted Butter, 80% – was the one that took out the top spot in our test, both overall and for taste alone.

Is grass-fed butter better for you?

Most cows (about 98%) in Australia are free to graze on pastures. However, grass-fed cows don't only eat grass. In Australia their diet is about 60–65% grass, with additional nutrition coming from hay, grains and legumes to provide a complete and balanced diet.

Grass-fed dairy has a slightly different nutritional profile to dairy products that come from regular-fed cows. Grass-fed cows produce milk with a slightly higher omega-3 content, beta-carotene and beneficial fats, so grass-fed butter may be slightly better for you than butter made with cream from cows not predominantly fed grass. 

Fourteen of the butters in this test were specified to be from grass-fed cows, with two of them labelled as coming from 'free-grazing cows'.


There is a science to making butter spreadable, and it's all about the crystals and the free fats. 

After the cream is pasteurised, it's cooled and left at 5℃ for about eight hours. This process causes about half of the milk fat in the globules to form crystals. The amount and size of these crystals help determine the texture of the butter. 

When the butter is finally produced, it's a matrix of fat globules, solid crystals and water droplets that are embedded in a mass of semi-solid 'free' fat. A high proportion of 'ordered' crystals leads to butter that is stiff and firm when cold. The amount of crystals compared to free fat determines the butter's spreadability. The free fat gives the butter more spreadability and tendency to leak liquid fat as the butter softens. 

We had our expert taste testers comment on the spreadability of the salted butters on soft white bread.

If you're keen to avoid shredded bread, here are some of the notable super spreaders: 

  • Ballantyne Salted Butter – "spreads easily when firm"; "nice spread, really easy".
  • Aldi Beautifully Butterfully Salted Butter – "best spreadability so far"; "smooth and easy to spread".
  • Absolute Organic Salted Butter – "spreads very easily, the softest of all butters"; "easy, spreads well".
  • Kerrygold Salted Butter – "texture is very good"; "easily spreadable".  
  • Dairy Farmers Salted Butter – "very good texture for spreading".

What butter do top chefs use?

Butter is versatile and can be used for baking, sauces and frying (though for frying you'll get a better result with clarified butter, which is butter that's had the milk solids removed, as it has a higher burning point). Adam Moore, a chef and food consultant who was part of our expert tasting panel, says that butter adds "depth into sauces, mashed potatoes, purees and steak". 

Adam says the type of butter that top chefs use will depend on what they're cooking, but they "usually use a cultured butter for more flavour".

His hot tip for home cooks is to try cooking with smoked butter to elevate your roast chicken to the next level, and flavoured butter (sweet or savoury) to enhance any dish.

Tips for buying, storing and using butter


  • Light and air can each cause oxidation of butter, which affects its taste. Oxidised butter is darker yellow on the outside where it has been exposed. Avoid buying inadequately wrapped products, and be mindful that butters packaged in semi-transparent white wrapping are more susceptible to surface oxidation than those wrapped in opaque foil due to risk of exposure to light during storage or transportation.  
  • Cultured butter has had live bacterial cultures added to the cream, which causes the butter to taste slightly tangier and have a more distinctive aroma. This is due to the fermentation process by the bacterial culture which converts milk sugar (lactose) into lactic acid. Culture was traditionally added to help extend the shelf life of butter, but today it's more often done to create a unique flavour profile. 


  • If serving butter at room temperature, only cut off the amount you know you'll use and leave the rest in the fridge. 
  • If you need to bring cold butter to room temperature fast, expert taste tester Adam More suggests grating it.  
  • Unsure whether to use salted or unsalted butter? CHOICE home economist Fiona Mair says it's not so important if you use salted or unsalted for your savoury meals as you can always adjust the salt throughout the cooking. Unsalted butter is ideal for sweet baking and savoury pastry as you won't run the risk of the salt overpowering other flavours. It can be used in all other cooking – just add your own salt if needed.


  • Storing butter requires coolness and darkness. 
  • Make sure your butter is tightly wrapped or stored in an airtight container. This will prevent exposure to oxygen and also prevent fridge odours from absorbing into the butter. 
  • Homemade butter will last in the fridge for up to two weeks, depending on the extraction of buttermilk and if salt was added. 
  • Butter can be frozen for up to 12 months if salted, and six months if unsalted.

How we test


We tested butters that are available at major supermarket chains and online, including salted, unsalted and cultured varieties. Price is based on price in stores for a 250g block or closest (not on special) in September 2022. A total of 44 supermarket products were tested. 


Our experts tasted the butter samples blind (without knowing the brands) in a randomised order.


Experts independently judged all butters, scoring each sample for flavour and aroma, texture and presentation. 

The overall score (what we call the CHOICE Expert Rating) is made up of taste 90% (50% flavour and aroma, 30% texture, 20% presentation) and nutrition 10% (100% Health Star Rating, calculated from the details in the nutrition information panel and converted to a percentage). 

We recommend products with a CHOICE Expert Rating of 75% or more.
