When it comes to wine storage, the choice of bottle liner plays a crucial role in preserving wine quality. Two commonly used liner materials, Saranex and Sarantin, each have unique characteristics suitable for different storage needs.
Saranex liners are made from a multi-layer co-extruded film containing ethylene-vinyl alcohol (EVOH), providing moderate oxygen barrier properties. With an oxygen transmission rate (OTR) of approximately 1-3 cc/m²/24 hours, Saranex allows a small amount of oxygen to permeate the bottle, which can accelerate wine maturation. This makes it ideal for wines meant for short-term consumption. The water vapor transmission rate (WVTR) of Saranex is also moderate, around 0.5-1.5 g/m²/24 hours, which is suitable for wines that will be enjoyed within a few months.
Sarantin liners, on the other hand, are made from high-barrier PVC materials with extremely low permeability, with an OTR as low as 0.2-0.5 cc/m²/24 hours, effectively slowing the oxidation process to protect the wine’s complex flavors. The WVTR is also lower, typically around 0.1-0.3 g/m²/24 hours, making Sarantin ideal for premium wines meant for long-term storage. Given its superior barrier properties, Sarantin is widely used for wines intended to age over years, ensuring that the quality remains unaffected by oxygen exposure.
In summary, Saranex is best suited for wines intended for short-term drinking, while Sarantin is optimal for high-quality wines meant for extended storage. By choosing the appropriate liner, winemakers can better meet the storage and drinking needs of their consumers.
