For centuries, winemakers have relied on time-honored traditions, aging in oak barrels, racking, fining, and polishing to achieve clarity, stability, and balanced sensory profiles. Yet in an era of exacting consumer expectations and stringent regulatory standards, these conventional methods sometimes struggle to maintain consistency and sustainability. Nanofiltration, an emerging membrane technology that offers precision control over molecular composition while preserving the wine’s nuanced flavors and aromas. By operating between ultrafiltration and reverse osmosis on the molecular scale, nanofiltration selectively removes or concentrates targeted compounds. This blog delves deep into the science and applications of nanofiltration in modern winemaking.
