Winemakers Reclaim Wine Quality And Value With New Molecular Filtration Tech
From premium winemakers in New Zealand to top-tier producers in California, amaea's selective, sustainable filtration solution, launched in late 2023, is being used to remediate and enhance wine quality. The proprietary MIP beads, imprinted with billions of binding sites, selectively target and capture unwanted molecules—such as pyrazines, ethyl phenols, and phenolic compounds responsible for sensory profiles—and remove them while preserving the wine's essential varietal character, color, and flavor.
'Winemakers face real challenges when unwanted, characteristics or impacts appear in their wines, that traditional methods cannot resolve,' says amaea CEO Aiden Tapping. 'Our molecular filtration solution gives them control to target and remove the compounds responsible for undesirable sensory profiles - without stripping away desirable characters. This recovers value, saves wine from being downgraded or discarded, and ultimately protects brand integrity.'
Wines tainted by 'off aromas,' such as those caused by stink bugs or pyrazines as well as wines that require significant bitterness management pose a major financial challenge for producers globally. Over the past year, amaea RMx technology for remediating 'off' aromas and wines impacted by frost, pyrazines, Brettanomyces, MOG and other challenges, and amaea PFx technology for palate fining, have supported over 50 unique producers in treating more than 400,000 gallons/ 1.5 million liters of wine, helping them recover an estimated USD$3.5 million/ NZD$6.2 million in wine value in the past 12 months.
'It's fantastic to see the consistent validation from the industry, highlighting the versatility and value of our technology,' says Tapping. 'We've focused on giving some of the top winemakers the confidence to try our technology, even on small volumes. Now, on the back of customer success, we're gearing up for an increase in the volume of wines treated by both existing and new customers as our technology gains market traction.'
Smart Polymer, Better Wines: Customer Successes
amaea's technology has successfully helped top winemakers recover wine to its intended program, high-quality and value, showcasing a wide variety of commercial customer applications:
Jackson Family Wines (US) has successfully trialled amaea to replace single-use fining agents by decreasing bitterness in hard-pressed white wine. Dr Caroline Merrell, Senior Manager of Winemaking Technical Services at Jackson Family Wines says: 'One area where we see a lot of potential is replacing single-use fining agents with reusable media, such as amaea's MIPs. During a recent trial, amaea's MIP treatment decreased bitterness and was preferred sensorially over wines treated with traditional fining agents. The results were impressive and will allow us to simultaneously improve quality in select wines while decreasing waste from single-use inputs.'
Cleomont Vineyards (NZ) increased the saleable quality of wine where traditional methods couldn't resolve the issues. Faced with a particularly phenolic 2024 Marlborough Pinot Gris, renowned New Zealand winemaker and grower Digger Hennessy, the owner of Cleomont Vineyards, reduced the wine's excessive bitterness and enhanced its sweetness, with amaea's MIPs selectively capturing the offending phenolic compounds. 'The wine didn't need a huge treatment. It got rid of the very annoying bitterness on the back palate that we were struggling to get out. The MIP treatment made it a lot smoother and now I'm happy with it.'
Marisco Vineyards (NZ) remediated a stink bug-affected wine back to its intended program. Marisco Vineyards celebrated an exceptional 2024 vintage. Yet, one block of Pinot Noir faced an unexpected issue when a species of Pentatomidae, commonly known as the Australasian green shield or stink bug, was found among some of the grapes. Traditional techniques for stink bug remediation focus on masking the distinctive vegetative aromas caused by the insects. However, amaea's highly selective technology removes unwanted molecules responsible for the undesirable vegetal and herbaceous traits. 'Having the ability to run wine through MIPs, knowing it won't physically change apart from removing the target molecules, is a massive plus,' says winemaker Alun Kilby, who sees endless potential applications for amaea's technology.
Giesen (NZ) used amaea PFx in place of gelatin (a fining agent), to address bitterness in their 0% Merlot. Consulting winemaker Duncan Shouler, former Director of Winemaking at Giesen Group, supports technology, change and innovation in the wine industry to stay relevant and evolve. At Giesen, he saw an opportunity to use amaea PFx in their 0% Merlot. 'Typically, when you remove alcohol from wine, certain traits and characteristics start to stand out. For Merlots, the tannins become prominent, and the warmth and sweetness are lost. For palate fining, gelatin is traditionally added, which, though effective at softening phenolic content, isn't vegan-friendly and isn't entirely selective, which means it removes more than is intended. At Giesen, when introduced to amaea PFx, we saw a technique that enabled us to balance polyphenols without relying on animal additions; it was environmentally conscientious and had the potential to provide a more financially sustainable alternative to traditional fining practices.'
Additional Applications: Remediating Smoke-Impacted Wine
In late 2023, amaea launched amaea VPx, its smoke remediation solution, which uses tailored MIPs in a one-pass filtration system. A 2024 WINnovation Award winner, amaea VPx technology successfully removes the volatile phenols from smoke-impacted wine to a level that sits below sensory thresholds.
To extend its position as a next-generation partner for quality-focused winemakers, amaea's MIP solutions, already commercially used in the United States, Canada, and New Zealand, will launch in Australia later this year with a future focus on Europe.

VexTrio exposed as global ad-fraud empire with billions in play
Infoblox Threat Intel has released details exposing the VexTrio threat group as a global business enterprise involved in large-scale ad-fraud activity. Previously categorised as a major participant in malicious traffic distribution systems, VexTrio is now understood to be a complex multinational corporate entity with a network of nearly 100 companies spanning the adtech, energy and construction sectors. The network reportedly underpins an ad-fraud scheme valued in the billions. Criminal structure The investigation by Infoblox Threat Intel outlines that VexTrio is not merely an assembly of hackers, but a merger of Italian and Eastern European criminal groups. They use a structural network of businesses to obfuscate fraudulent activities. Named executives run operations which, according to the findings, have persisted for more than a decade. VexTrio is described as managing a comprehensive scam supply chain, controlling all elements from the creation of fraudulent applications to the operation of payment processors that collect illicit proceeds. Prominent adtech brands within the network, including Los Pollos, TacoLoco, and Adtrafico, function as outwardly legitimate affiliate marketing platforms while, in reality, serving the group's criminal operations. "For years, we thought that VexTrio was just a group of basement hackers," said Dr. Renée Burton, Vice President of Infoblox Threat Intel. "This investigation proves that behind the malicious links is a highly organised, multinational corporate entity that has been profiting from fraud on a massive scale. They have built an entire adtech industry to conceal their crimes in plain sight." International reach Infoblox reports that VexTrio's reach is substantial. In 2024, their affiliate network Los Pollos reported more than 2 billion unique users each month. GoDaddy, reviewing compromised websites, found that around 40 percent were redirecting traffic to VexTrio. Additionally, one of the group's core Content Delivery Network domains ranks among the world's top 10,000 most visited domains. The breadth of control extends to fraudulent product development, encompassing fake dating platforms, eCommerce portals and cryptocurrency investment websites. VexTrio operates its own payment processing and runs email validation services, enabling high-volume spam campaigns used to direct new victims into their schemes. Financial incentives and technical setup According to Infoblox, affiliates operating through VexTrio's network are offered incentives surpassing USD $100 per lead for fraudulent antivirus products. Some schemes, such as "blank credit card" scams, are promoted with claims of returns in the six-figure range and up to 300 percent return on investment. The underlying infrastructure supporting the network is described as efficient and advanced. Despite its scale, VexTrio reportedly runs fewer than 250 virtual machines globally, employing automated tools and leveraging multiple hosting and legitimate Content Delivery Network providers to avoid detection and ensure ongoing operations. This technical approach enables the group to remain both resilient and difficult to track. Business fronts and adtech complicity Central to VexTrio's evasion tactics is its use of shell companies and the portrayal of its businesses as reputable adtech providers. The investigation highlights that these companies operate under several brands in the affiliate marketing space, while simultaneously conducting various forms of fraud. The report by Infoblox suggests that adtech industry platforms facilitate the expansion of cybercrime at scale. The research further notes that affiliate networks such as Los Pollos, TacoLoco, and Adtrafico not only increase the syndicate's reach but represent potential points of exposure. As these networks track affiliate activities, they hold intelligence capable of identifying those responsible for website compromises and widespread defrauding of internet users. Researchers argue that these findings underscore the need for increased accountability and transparency in the adtech sector. The examples of compromised affiliates and fraudulent affiliate marketing tactics are presented as risks to internet safety and business integrity worldwide.

Blackpearl opens retail offer after AUD $10.3m raise & US deal
Blackpearl Group has opened its retail entitlement offer at AUD $0.95 per share, following a AUD $10.3 million institutional raise led by Australian cornerstone investors ahead of its proposed listing on the Australian Securities Exchange as a foreign-exempt entity. The retail component of the entitlement offer allows eligible shareholders to participate following the completion of the offer's institutional stage, which has attracted backing from prominent Australian institutional investors. This development comes as the company finalises its acquisition of US-based AI sales automation firm B2B Rocket, a transaction expected to raise Blackpearl's annual recurring revenue (ARR) to USD $17.5 million and set the direction towards a USD $50 million target. Australian support The institutional element of Blackpearl's accelerated non-renounceable entitlement offer (ANREO) and additional placement successfully raised AUD $10.3 million. The support from Australian investors is crucial as Blackpearl progresses its application for an ASX foreign-exempt listing, a move intended to broaden its investor base and reinforce its presence in the world's largest market for small and medium businesses. Chief Executive Officer Nick Lissette said the offer aligned with the company's broader ambitions: Blackpearl isn't in the habit of standing still. Investor demand has been clear and with Australian cornerstone support in place and our ASX pathway progressing, we're opening the retail window for eligible shareholders today. This is a rare moment - a New Zealand AI company acquiring a cutting-edge high growth US technology business, backed by Australian institutions and preparing for an ASX quotation. The raise materially broadens our investor base and strengthens our platform to scale in the world's largest SMB market. Lissette stated that the opening of the retail offer reflects a significant step in Blackpearl's expansion strategy. The offer opened to eligible shareholders on Monday 18 August and will close on 25 August, giving participants the opportunity to subscribe at AUD $0.95 per share. Oversubscriptions will be permitted for those who fully take up their entitlement. Acquisition and growth targets Blackpearl's pending acquisition of B2B Rocket, an AI sales automation business based in the United States, is expected to close this week. The company projects that this acquisition will lift ARR to USD $17.5 million, with momentum towards USD $20 million as it maintains a long-term target of USD $50 million. Lissette added: We're not inching forward, we're leaping. With B2B Rocket closing this week, we're in striking distance of $20m and so we're now focused on our $50m target. This is the growth story NZ tech needs right now. It's proof that Kiwi innovation can scale - and compete - anywhere and signals that NZ Tech belongs in the big leagues globally and has what it takes to deliver. Next steps for listing Blackpearl targets its ASX quotation in approximately three months, contingent on the successful completion of a Tier 1 standard audit of B2B Rocket. The company sees institutional support from Australia as pivotal in this phase. Lissette stated: Australian institutional backing gives us more than capital; it gives us confidence and credibility as we scale. Use of proceeds Proceeds from the entitlement offer will be used to fund the B2B Rocket acquisition, support the scaling of Bebop's growth, integrate B2B Rocket and execute its go-to-market plan, enhance Blackpearl's Data Wholesale resources, and maintain a cash buffer for working capital purposes. Lissette summarised the company's outlook: We're not just building a bigger business, we're building a bigger playing field. This particular combination of capital, capability and opportunity doesn't come around often and we intend to use it to take New Zealand AI global. Follow us on: Share on:

From Trade Gains To AI Dividends: APEC's Next Growth Play
Cooling Growth, Lingering Risks APEC's growth slowed to 3.5 percent in the first quarter of 2025, down from 3.8 percent a year earlier, reflecting weaker demand and heightened global uncertainty. Early trade gains, driven by businesses rushing to ship goods before new trade restrictions take effect, gave the economy a short-term boost. However, sustained momentum requires consistent reforms and renewed investment in productivity. Regional growth is now projected at 3.0 percent in 2025 and 2.9 percent in 2026, slightly above the May 2025 APEC Regional Trends Analysis forecasts, but trailing behind the rest of the world, which is expected to grow by 3.4 percent in 2026. Despite the emergence of new technologies and the relative resiliency of greenfield investments in productivity-enhancing projects, downside risks are expected to dominate, marked by policy uncertainty, geopolitical tensions, and elevated debt levels as legacy from the pandemic. Central Banks Balance Support and Stability Inflation averaged 2.5 percent across APEC in the second quarter of 2025, lower than a year ago and easing pressure on households and businesses. In response to downside risks, the majority of central banks have trimmed policy rates to help spur economic activity. Other APEC economies have kept their policy rates unchanged, maintaining a cautious stance amid potential price pressures and external shocks. In recent months, oil prices edged higher as energy markets responded to shifting supply dynamics amid geopolitical instability. In contrast, food prices remained broadly stable, reflecting mixed movements across key commodity groups. Trade Gains Reflect Precautionary Activity Merchandise trade in APEC posted solid growth in the first quarter of 2025 as businesses moved shipments forward, hedging against possible new trade restrictions. Export and import values rose by 5.0 percent and 7.7 percent, respectively, while volumes climbed even faster, by 7.0 percent and 7.9 percent. This expansion suggests that early-year trade gains were driven by risk-mitigation strategies rather than a sustained rebound in demand, and may taper off as temporary factors fade. Trade momentum remains highly sensitive to policy developments. Services trade told a different story. Export growth slowed to 6 percent in the first quarter of 2025 from 11 percent a year earlier. Travel services exports contributed to the decline as it decelerated sharply to 9 percent from 30 percent over the same period even as transport and other commercial services increased. Trade policy uncertainty, although easing from earlier peaks as negotiations gain traction and trade deals begin to take shape, has remained well above historical norms. In fact, financial markets reflect amplified investor concerns, with gold prices near record highs and demand for safe-haven assets is strong. Emerging Opportunities: Resilient Greenfield Investments and AI Potential Although FDI inflows have moderated, falling from USD 1,157 billion in 2021 to USD 956 billion in 2024, greenfield investment remains a bright spot. Announced greenfield projects in APEC reached USD 595 billion in 2024, up 56 percent compared to the level in 2021, underscoring investor confidence in new capacity and innovation. Sustained investments in innovation and digitalization signal an ongoing shift toward productivity-enhancing sectors, which bodes well for APEC's growth trajectory. Digital technologies, particularly artificial intelligence (AI), are poised to amplify these gains. Modelling estimates suggest that, when treated as a productivity shock, AI adoption could raise GDP by 1.3 to 3.9 percent. On average, APEC economies already score above global averages on AI readiness, highlighting strong potential to capture digital dividends. Still, digital capacity remains uneven across the region, with persistent gaps in digital skills limiting broader adoption. Closing these gaps will be key to unlocking AI's full economic potential and ensuring that its benefits reach all people, across communities, sectors and economies. Policy Priorities: Strengthening Confidence, Harnessing Digital Gains With growth moderating and uncertainty still elevated, APEC economies must walk a fine line, preserving near-term macroeconomic stability while advancing structural transformation. Tackling current headwinds and fostering innovation to lay the foundation for sustained growth that benefits the entire population will require coordinated policy action across three key areas: Inclusive Structural Reform: Advance labor market reforms and scale up digital skills development to strengthen human capital and ensure that the benefits of AI-driven productivity are widely shared. Adaptive Economic Policy: Maintain flexible macroeconomic frameworks, rebuild fiscal space, and channel investment toward sectors that boost productivity to support adjustment and resilience. Coordinated Regional Cooperation: Use APEC's platform to align responses to shifting global environment, reinforce regional economic stability, and deepen integration through sustained dialogue. As APEC economies navigate persistent global uncertainty, it is important to strike a careful balance between policy responses that yield short-term gains and structural reforms that drive enduring momentum and productivity growth. Regional cooperation is indispensable in today's uncertain environment. APEC as a regional platform must continue to foster open dialogue, align policies, and coordinate responses to shared challenges. Clear direction and consistent collaboration are vital to managing risks and supporting durable, innovation-driven growth.
