As an expert sommelier and brewer, I have had the opportunity to taste and evaluate a wide range of whiskies, including both Johnnie Walker Blue Label and Royal Salute. While both of these whiskies are considered to be premium options, they do have their own unique characteristics and qualities.
When it comes to the issue of oxidation, it is important to note that all whiskies can be affected to some degree by exposure to air. However, there are variations in how different whiskies respond to oxidation. In the case of Johnnie Walker Blue Label, I have personally found that it tends to be more resistant to changes in flavor after opening. Even after extended periods of time, the taste of Blue Label remains remarkably consistent. This can be attributed to the carefully selected blend of whiskies used in its production, which ensures a well-balanced and stable flavor profile.
On the other hand, Royal Salute, while also a high-quality whisky, may exhibit some changes in flavor following opening. However, it is worth noting that this can actually be viewed as a positive characteristic for some whiskies. Some connoisseurs believe that certain whiskies can benefit from a bit of oxidation, allowing the flavors to mellow and develop more complexity over time. Therefore, the fact that Royal Salute may improve following opening can be seen as a desirable trait by those who appreciate the evolution of flavors in their whisky.
Ultimately, the preference between Johnnie Walker Blue Label and Royal Salute comes down to personal taste and the specific qualities one is looking for in a whisky. Blue Label offers a consistent and unchanged flavor profile, making it a reliable choice for those who enjoy a consistent experience. On the other hand, Royal Salute presents an opportunity for the flavors to evolve and develop, which can be appealing to those who appreciate the complexity that comes with aging and oxidation.
Both Johnnie Walker Blue Label and Royal Salute are exceptional whiskies in their own right. The resistance to oxidation displayed by Blue Label sets it apart as a whisky that remains unchanged in flavor even after opening. On the other hand, Royal Salute's ability to improve and develop in flavor following opening can be seen as a positive characteristic for those who appreciate the evolution of flavors in their whisky. Ultimately, the choice between the two comes down to personal preference and the desired experience one is seeking from their whisky.
