amaea RMx for Pyrazines
Targeted pyrazine remediation
Overcome a challenging harvest with amaea RMx, a first-of-its kind solution designed to help alleviate green aromas in wine.
CASE STUDY
Releasing green in Sonoma County
Cooler than average harvest conditions left a US winery with prevalent green aromas in their Cabernet Sauvignon. Looking for a solution focused on value recovery, they turned to amaea’s molecularly imprinted polymers. The result was a wine that offered more fruit-forward characters.
Managing green aromas in the winery
The class of compounds responsible for the “green” and “vegetal” aroma found in wines are pyrazines, with IBMP (isobutyl methoxypyrazine) identified as a prominent pyrazine also associated with immature grapes.
At low concentrations, pyrazines can be considered a regional or varietal hallmark however, when present above sensory thresholds, i.e., 2-5 ppt (ng/L), the concentration creates significant sensory challenges for winemakers.
By blending, or using advanced winemaking techniques, winemakers can shift the sensory profile to be more fruit-forward. However, these techniques often distract from other desirable features of the wine.
Targeted remediation focused on quality improvement
amaea have developed amaea RMx, an innovative molecular filtration solution designed to selectively target capturing the pyrazines responsible for the green aromas found in wines. By capturing molecules, such as IBMP, the molecularly imprinted polymers (MIPS) reduce the offending green aromas to reveal more of the varietal character of the wine.
By using amaea RMx winemakers are able to:
Reduce pyrazine concentration
Adjust treatment rates to customize sensory outcomes
Enhance the quality of their wine
What’s happening in the wine?
Laboratory analysis of Cabernet Sauvignon wines treated using amaea RMx showed the concentration of IBMP was reduced by up to 23%.
For the purpose of this study, IBMP was used as the analytical marker.
How did it taste?
81 winemakers’ sensory feedback on a 2022 Cabernet Sauvignon treated using amaea RMx reflected a reduction in green, vegetal, and astringent notes, resulting in the wine becoming more fruit forward.
Low-impact production process using regenerable polymers
amaea RMx uses a standard filtration system that is easy to implement and quick to administer. As the wine passes through the columns, the IBMP molecules bind to the MIPs. Once saturated, the MIPs are regenerated using an eluent, ready to be used again.
The result is a more sustainable, low-impact process built for precision and value recovery.
