“Before we used the ALKOvin™ active liner, we struggled with reductive off-flavours year after year in wines sealed with tin-lined screw caps. After six to nine months in the bottle, the original fruity flavour disappeared, and the wines were very closed, inexpressive, and deteriorated from then on. As a result, we were looking for a solution to this problem.
The ALKOvin™ active sealing liner was used for the first time in 2019 when bottling our basic tier wines. Working with this liner was exceptionally smooth. We only had positive feedback regarding the tightness and the outlier rate – the liner was completely within the tolerance range. Furthermore, the SO2 content was extremely stable after 9 months. In terms of aroma and fruit preservation of our wines, we experienced a significant increase in quality in comparison to previous years. This was confirmed by comparative blind tastings among colleagues against the conventional tin liner. The ALKOvin™ active variants were consistently perceived by all tasters as cleaner by smell, fruitier and crispier, with significantly more structure on the palate.
Switching to the ALKOvin™ active sealing liner was a pioneering move and the right decision for us for the future.”
