The use of Crown Seals
Charles Sturt University Winery uses crown seals for our premium sparkling wines to ensure their quality is not compromised by the closure. Sparkling wine quality is as much under threat from cork closures as still wine is, possibly more so. Crown seals also deal with any safety issues that may arise from opening bottles that are under pressure.
Crown seals are the preferred closure for tiraged wines with Australian and French (Champagne) premium sparkling wine producers and have been for a considerable time. They're hidden from the public eye while the sparkling wine is going through its bottle fermentation and maturation, a period that may extend for many years. The crown seal is removed at disgorging and cork only introduced for presentation to consumers.
It is important that our customers enjoy our sparkling wines at their best and the use of crown seals will ensure that the quality of our sparkling wines are not compromised and are presented as the wine maker intended.
All CSU sparkling wines are produced in small quantities using the traditional method and spend extended periods on yeast lees to develop flavour and complexity.
