Pepsi Max gets maximum results in cola review for 2nd year in a row

Cola is soda-licious! In fact, a recent Canstar Blue survey found that it’s Aussies’ favourite soft drink flavour before lemonade and ginger ale. Besides the everlasting debate over Coca-Cola versus Pepsi and which is better than the other, everyone can agree that cola is a refreshment like no other. But if you’re still unsure which cola product or brand is best, don’t stress. We’ve researched to find out which colas fizzle and which fall flat.

We asked more than 900 Aussie consumers to rate the different products and brands of carbonated cola they’ve purchased from a supermarket or grocer and consumed within the last three months. Survey respondents rated products independently on important factors like taste, packaging design, value for money and overall satisfaction. Brands that met the minimum required survey sample size (30 responses) are included in the results.

Aussies have rated Pepsi Max best for the second year running, giving it five-star reviews for all categories! These include taste, range variety, packaging design, value for money and overall satisfaction.

Best Cola Brands

Pepsi Max

Here are the best cola brands in Australia, as rated by consumers in Canstar Blue’s 2021 review:

  1. Pepsi Max
  2. Pepsi Regular
  3. Coca-Cola
  4. Coke Zero
  5. Diet Coke

Pepsi Max once again slurped up a five-star review for overall satisfaction, while most other brands settled on a respectable four stars. The only exception was Diet Coke, which got three stars overall.

It’s worth noting that when it comes to variety, shoppers aren’t just pouring themselves a glass of Pepsi Max. Coke Zero and Diet Coke also scored full marks, similar to Pepsi Regular and Coca-Cola when judged on packaging design.

Cola Brands

Pepsi Max

Pepsi Max review

Pepsi Max is marketed as the low-calorie, sugar-free version of classic Pepsi. It’s crisp, refreshing and marketed as offering ‘max taste, no sugar’ and if our survey results are anything to go by, Aussies definitely agree. Pepsi Max comes in a few different flavours, including:

  • Pepsi Max
  • Pepsi Max Vanilla
  • Pepsi Max Raspberry
  • Pepsi Max Creaming Soda

Prices for a Pepsi Max 1.25L bottle start from $2.35 in most supermarkets, though you can often pick up the 2L bottle variety for even less ($2.10). Supermarkets work in mysterious ways!

  • Pepsi Max was rated the best cola product across the board for taste, packaging design, value for money and overall satisfaction.


Pepsi review

Pepsi is one of the most recognisable brands globally, thanks to its distinctive blue labelling, original taste and iconic marketing campaigns throughout the years. It’s long been a popular refreshment for any shindig and meals with friends. The Pepsi range includes:

  • Pepsi Regular
  • Pepsi Max
  • Pepsi Light
  • Pepsi Zero Sugar

Prices for a 1.25L bottle of Pepsi start from $2.35 in most supermarkets.

  • Pepsi achieved five stars for packaging design and four stars in the remaining areas, such as taste, variety, value for money and overall satisfaction.


Coca Cola review

Everyone knows the taste of Coca-Cola. That’s why the recipe for the classic Coca-Cola has remained unchanged for more than 130 years. Coca-Cola comes in a wide range of original and limited edition flavours and also as an energy drink for that extra caffeine hit. Some Coca-Cola products include:

  • Coca‑Cola
  • Coca‑Cola Vanilla
  • Coca‑Cola Cherry
  • Coca‑Cola Orange

A 1.25L bottle of Coca-Cola costs about $3.15 from most supermarkets, but like with Pepsi Max, you can often pick up a larger bottle for less!

  • Coca-Cola scored five stars for packaging design, four stars for taste, variety and overall satisfaction; and three stars for value for money.

Coke No Sugar

Coke No Sugar review

Coke No Sugar aka Coke Zero offers (nearly) the same classic Coca-Cola taste but without the… sugar, duh! Instead, it’s sweetened with the same sugar alternatives as Diet Coke. Coke Zero products include:

  • Coca-Cola Zero
  • Coca-Cola Zero Vanilla

A 1.25L bottle of Coke Zero can cost about $3.15 from most supermarkets.

  • Coke Zero was rated five stars for range variety, four stars for packaging design, value for money and overall satisfaction, but fell flat with three stars for taste.

Diet Coke

Diet Coke review

Diet Coke, sometimes also referred to as Coca-Cola Light, delivers a distinctively unique and lighter taste to classic Coca-Cola. It’s sugar-free and contains next to zero calories. Products include:

  • Diet Coke
  • Diet Coke Caffeine-Free
  • Diet Coke Vanilla

A 1.25L bottle of Diet Coke costs about $3.10 from any supermarket.

  • Diet Coke was rated five stars for variety, four stars for packaging design, but finished on three stars in the remaining categories, including taste and overall satisfaction.

Is cola bad for your health?

The refreshing ‘bite’ from cola might be the perfect way to finish off a burger and fries, but sugary drinks should only be consumed in moderation. Cola contains caffeine, which can have short-term benefits like increased energy and improved mood. However, regular or excessive consumption could cause anxiety and adverse effects on your health long-term.

Our research found that almost one in four people surveyed (23%) feel guilty about drinking soft drinks, while 16% of respondents have tried to give up the sweet stuff. Alternatively, 21% of consumers surveyed said they opt for sugar-free varieties because they believe they’re healthier.

Which cola should I buy?

Ahh that’s a question for the ages. As expected, our survey found that taste is the biggest driver of satisfaction for cola consumers. So, you’ll want to consider whether you prefer a cola with bolder notes of vanilla, cinnamon and citrus, or if you’re more attuned to sweeter cola syrupy flavours. The general consensus is that Coca-Cola products are distinctively bolder in taste, while Pepsi products and supermarket cola brands are usually sweeter in flavour.

Don’t forget though that cola syrups and soft drinks more broadly are high in sugars. So, if you’re looking after your waistline, you may want to opt for zero sugar or ‘light’ cola products. Look at the nutritional information label of different products and check out the calories per serve as well as the ratio of sugars and sweeteners, to food acids and carbonated water.

Frequently Asked Questions

Canstar Blue surveyed more than 3,000 Australian adults across a range of categories to measure and track customer satisfaction, via ISO 26362 accredited research panels managed by Qualtrics. The outcomes reported are the results from customers within the survey group who have purchased (from a supermarket or grocer) and consumed carbonated colas in the last three months– in this case, 958 people.

Brands must have received at least 30 responses to be included. Results are comparative and it should be noted that brands receiving three stars have still achieved a satisfaction measure of at least six out of 10. Not all brands available in the market have been compared in this survey. The ratings table is first sorted by star ratings and then by mean overall satisfaction. A rated brand may receive a ‘N/A’ (Not Applicable) rating if it does not receive the minimum number of responses for that criteria.
