11th International Cool Climate Wine Symposium (ICCWS) 2026
Come join us at the 11th International Cool Climate Wine Symposium (ICCWS) in the city of Ōtautahi Christchurch, Aotearoa New Zealand.
During this event you will have the opportunity to learn about how winemakers are using amaea’s molecular filtration technology, it’s applications and the latest developments from our R&D team.
Presentation: High-speed, low-energy cold stabilisation with amaea CSx
Date: Wednesday 28, January 2026
Time: TBC
Presenter: Dr Aaron Low - Chief Technical Officer, amaea
Cold stabilisation remains one of the most energy-intensive steps in winemaking, with wineries conventionally relying on extended refrigeration below 0°C for more than a week. This process not only consumes significant energy but also limits flexibility. Alternative methods such as the addition of stabilizing agents, using electrodialysis, ion exchange or CTS can introduce costs, reliability issues or changes to wine pH. These constrain winemakers’ ability to achieve consistent potassium bitartrate (KHT) stability without trade-offs in sustainability or additional steps to retain quality.
To address these challenges, amaea has developed amaea CSx, a novel molecular filtration solution designed to deliver KHT stability, 85% faster and with up to 85% less energy use than conventional cold stabilization practices. amaea CSx uses a low-impact, one-pass filtration system combining heat exchange technology with functionalized, reusable crystals. This enables wineries to achieve instant, on-demand stabilisation to user-specified conductivity levels without additives, additional processing steps, or long hold times.
Delivered as a mobile filtration service, amaea CSx provides winemakers with an accessible, scalable, and more sustainable alternative for cold stabilization.
This presentation will detail the underlying principles of amaea CSx’s advanced technology, present real-world performance data, and highlight the potential of molecular filtration to transform cold stabilization into a faster, and more energy-efficient process for modern winemaking.
Poster: From Oxidation to Opportunity - Precision Molecular Filtration Saves Hawke’s Bay Wines
Authors: Jason Stent - Winemaker, Paritua Wines; Dr. Sylvia Baars - Head of Science, amaea
The 2022 and 2023 vintages in Hawke’s Bay presented Paritua Wines with significant challenges. A series of difficult growing conditions left some of the wines low in tannin and colour, some of these tanks of wine were in prolonged storage post-cancelled export orders. During this time, they developed oxidative characteristics. These challenges rendered the wines commercially unsellable and at risk of loss.
Recognising the need for substantial remediation, winemaker Jason Stent sought an innovative approach to recover value from the affected lots. He trialled amaea RMx, a New Zealand–developed molecular filtration technology designed to selectively capture and remove unwanted compounds to unmask the desirable aromas and flavours hidden in the wine.
The trial delivered compelling results. Oxidative notes in the wines were noticeably reduced, while brightness and varietal fruit expression were restored. In particular, the Merlot showed remarkable improvement: the muted, oxidised profile was replaced by fresh, vibrant fruit character. This recovery enabled Paritua Wines to blend, bottle, and successfully market the Merlot offshore — turning a potential write-off into a commercial success.
