The aronia berry is high in polyphenols. Other berries containing this compound include bilberries.<\/p>\nThey\u2019re small, round, purple, full of good-for-you polyphenols, and very Instagrammable.<\/p>\n
If you think I\u2019m talking about a\u00e7a\u00ed, the national fruit of Brazil and latest superfood craze to hit Irish breakfast and brunch bowls, you\u2019d be mistaken.<\/p>\n
I\u2019m talking about a berry you\u2019ve probably never heard of.<\/p>\n
One that grows abundantly right here in Cork \u2013 the aronia berry.<\/p>\n
Before we get into aronia, let\u2019s begin by diving into what a\u00e7a\u00ed is.<\/p>\n
I came across a\u00e7a\u00ed on a visit to California 15 years ago in an ocean-front caf\u00e9 where smoothie bowls were as new to me as this fruit, which grows in the Brazilian Amazon.<\/p>\n
The aronia berry is high in polyphenols. Other berries containing this compound include bilberries.<\/p>\n
When the colour purple shows up in foods such as fruits, it\u2019s a sure sign that a natural compound called polyphenol is present. These compounds are why fruits like a\u00e7a\u00ed and blueberries have been labelled as superfoods in recent years.<\/p>\n
Polyphenols are plant compounds called phytonutrients made by plants to boost their natural immunity. When we consume foods that have a high level of polyphenols, it sends a chemical signal to switch on our body\u2019s own protective and regenerative responses at a metabolic level.<\/p>\n
A\u00e7a\u00ed is high in these compounds, which is why they first caught on in a health-focused place like California. These fruits also contain resveratrol and, as a Californian friend said to me: \u201cIn California, with our vibrant wine culture, anything with polyphenols, resveratrol, or the halo of dark blue foods, is incorporated immediately into our diets.\u201d<\/p>\n
These \u201cdark blue foods\u201d include not just a\u00e7a\u00ed, but also the north American blueberry. Closer to home, the Irish native bilberry (a cousin of the blueberry also known as fraughan, hurts, or wild blueberries), blackcurrant, blackberry, cherry and red grape (hence, wine) are also included.<\/p>\n
The least known is the aronia berry.<\/p>\n
What are they, how are they different from other berries, and why should we pay them attention?<\/p>\n
To get to the bottom of these questions, I asked an expert.<\/p>\n
Dr Steve Collins is a medical doctor renowned for his pioneering work in the treatment of malnutrition in famine-stricken war zones around the world. In short, he knows a thing or two about what to feed our bodies to recover, regenerate, and be resilient.<\/p>\n
He is also an organic farmer of blueberries and aronia on Derry Duff Farm, high in the hilly terrain of the Bantry peninsula, and has developed a range of aronia products called Phyterberry.<\/p>\n
While many of us are familiar with blueberries, aronia is a different kettle of berry. Few know what they are, what they taste like, if we should be eating them, and why they are a better choice than a\u00e7a\u00ed for our Instagram-worthy smoothie bowls.<\/p>\n

Steve and Claire Collins became owners of Derry Duff Farm two decades ago.<\/p>\n
The primary reason aronia is better for us is because they have the richest source of polyphenols and contain more types of them than any other fruit or vegetable.<\/p>\n
But what does this mean?<\/p>\n
\u201cAronia has got this great mix of all major classes of polyphenol,\u201d explains Steve. \u201cCoffee has one type (chlorogenic acids), chocolate has another called PAX (or, proanthocyanidins), blackcurrants have a lot of a polyphenol called anthocyanins, but aronia is the only one that has the whole group.\u201d<\/p>\n
This is an important differentiator as each type of polyphenol contributes in different ways.<\/p>\n
\u201cThat\u2019s why it\u2019s a really good berry,\u201d says Steve. \u201cI\u2019m certainly not saying don\u2019t just eat aronia, but in conjunction with eating as much fruit, veg and berries as possible, you won\u2019t go wrong!\u201d<\/p>\n
Polyphenols contribute to better health by working on a metabolic level. Most of us might think of this as the measure by which we most effectively burn calories, but it also contributes to how we store and access energy, how effective our immune system is, how well our bodies manage hormone balance, mental function, and cellular repair.<\/p>\n
Because aronia has the highest number of polyphenols and a greater mix of all types, they are an easy way to incorporate more polyphenols into our everyday diet. Yet most of us consistently don\u2019t consume enough to support better metabolic health in a meaningful way.<\/p>\n
How do we know if we have good metabolic health?<\/p>\n
\n \u201cYou feel it in vitality; you don\u2019t get those slumps in energy,\u201d says Steve. \u201cThink of the cycle of craving food and crashing. A lot of the foundation of metabolic health is to do with glucose, metabolism, and insulin because that\u2019s our main fuel.\n <\/p>\n
\u201cGood metabolic health is about keeping the machine running. To use the analogy of a car engine: Mechanics know that they can fix a broken piston, but it\u2019s much better to change the oil. Keep changing the oil in an engine, it runs much better, and pistons won\u2019t break. Western medicine just wants to change the piston, but each time it does without changing the oil, the engine gets weaker and not as strong as it was.\u201d<\/p>\n
This may be layman\u2019s terms for the science, but in a world peppered with often confusing advice around food and health, it\u2019s challenging to cut through the noise \u2013 and why you\u2019ve heard of a\u00e7a\u00ed but not aronia.<\/p>\n
A\u00e7a\u00ed is naturally very tart and bitter (ever eaten a sloe; like that), so to make it palatable, lots of sugar is added.<\/p>\n
\u201cThis is the main issue I have with a\u00e7a\u00ed,\u201d says Steve. \u201cBecause of all the added sugar, you get a metabolic penalty. Even though a\u00e7a\u00ed directly acts to lower blood sugar after eating carbohydrates, because the berries have been loaded up with sugar, that hugely undermines the effectiveness of the polyphenols.\u201d<\/p>\n
Aronia contains sugar – it is a fruit, after all, occurring as fructose and sucrose, but in much lower quantities than other fruits.<\/p>\n
\u201cWith aronia, it\u2019s much less. Even our new 100% Irish Aronia Juice, which is naturally sweeter than our original juice made from aronia sourced from organic farms in Poland, is still way less than orange, apple, or any other juice.\u201d<\/p>\n
There\u2019s more to aronia than its array of polyphenols, which makes this berry truly super. It\u2019s also that it can grow anywhere, even in poor marginal soils, just like Steve found he had when he purchased his farm in the Borlinn Valley nearly two decades ago.<\/p>\n
Aronia is a resilient plant that thrives where other plants would fail to even grow. Marginal land with shallow soils, poor nutrition; drought, flood, wind – factors that would send shivers down the spines of most farmers – are no concern to these plants.<\/p>\n
As they grow, they send down deep roots that anchor them, allowing them to source moisture and nutrients from way down in the substrate. There is very little that can kill them off and, because they will grow where little else can, it provides a new opportunity for farms to create income from previously unproductive land.<\/p>\n

Aronia growing at the West Cork farm. Aronia is a resilient plant that thrives where other plants would fail to even grow.<\/p>\n
\u201cWhen Phyterberry began, we set out not only to highlight the nutritional properties of aronia, but also to create a local supply chain that would enable farmers to grow this resilient and sustainable crop,\u201d says Steve.<\/p>\n
To do this, Steve\u2019s team created a range of products to demonstrate consumer demand for aronia-based products to encourage farmers to plant aronia. In turn, Phyterberry committed to buying the annual crop, guaranteeing additional income for farmers.<\/p>\n
The results are showing. In 2025, Steve produced the first batch of 100% Irish-grown organic aronia juice.<\/p>\n
\u201cIt\u2019s slow, but it\u2019s happening. Drive up the Borlinn Valley, you\u2019ll see a little acre of aronia on both sides of the road. We\u2019ve got plantations going in this year in Hook, Co. Wexford; a guy in Lismore, Co Waterford, who produced for us last year, a lady near Killarney, Co Kerry, with four acres in, and a farmer in the UK with a big estate who put in 20,000 plants,\u201d says Steve.<\/p>\n
\n \u201cIn Ireland now, we\u2019ve probably got farmers with about 15,000 plants in, if not more. That\u2019s about 12 acres. It\u2019s small, but it\u2019s a definite start, and each year that amount is increasing.\u201d\n <\/p>\n
Whereas the bulk boxed juice made from Polish-grown aronia has a drier tannic flavour best consumed either as a daily gut-shot or diluted with sparkling or still water, the 100% Irish juice has a very pleasing demi-sec taste like pomegranate juice. Its soft tannins and complex fruit flavours mean it can easily be enjoyed as an alcohol-free wine substitute.<\/p>\n
\u201cBecause the juice has tannins from the anthocyanins, it\u2019s a really good wine replacement,\u201d says Steve, \u201cand it has appeared on the non-alcoholic wine pairing at the two Michelin-starred restaurant in Baltimore, Dede at The Custom House.<\/p>\n
\u201cFor me,\u201d says Steve, \u201cThe 100% Irish aronia juice is the one I drink for pleasure, and the Polish aronia is the one I drink for health!\u201d<\/p>\n
Each 330ml bottle of 100% Irish aronia juice equates to three measures of the daily amount of polyphenols. This makes it easy to boost intake of polyphenols which, says Steve, is pretty low.<\/p>\n
\u201cThere isn\u2019t an official suggested recommended daily intake right now, but scientific literature suggests 2,000mg a day total intake from all food and drink is necessary for good overall health.\u201d<\/p>\n
A small study conducted in Cork estimated the average daily adult intake is 530mg a day. A major study conducted in Spain, PREDIMED, looking at health issues associated with poor metabolic health, concluded outcomes were greatly improved with a daily polyphenol intake above 1200mg per day.<\/p>\n
\u201cI think when [a recommended daily amount does] happen, it\u2019ll be around 2000mg per day, but really, you\u2019ve got to get your intake over 1200mg to be in that safe zone.\u201d<\/p>\n
If we spent all our days eating blueberries, cherries, blackcurrants, blackberries and elderberries (another local fruit high in polyphenols), drinking coffee, wine and eating chocolate, we might hit that goal. It reads like a borderline hedonistic way to live, but expensive, highly caffeinated and fairly boozy.<\/p>\n
To counter that, Steve and his team have developed a range of Phyterberry products in addition to the juices that are adaptable to how people live their lives, including an aronia essence which can be diluted or added into porridge or yoghurts in a range of functional powders.<\/p>\n
Aronia Focus powder is made from the dried cake left from pressing berries into juice, so it also contains essential fibre to feed the gut. It can be mixed with natural yogurt, topped with seasonal Irish fruits, and scattered over with bee pollen and granola made from Irish grown oats to give you all the taste, look and feel of a pricey a\u00e7a\u00ed bowl, but with everything grown right here in Ireland.<\/p>\n
