If we look at how the Japanese whiskey market has exploded over the last couple of years and how hard it is to come by in Europe these days, one would almost say Japanese whiskey is the way to go.
This might be why the Scottish whiskey producers are moving away from age statements on labels these days. They have seen how popular the product has become and are having a hard time to keep up with demand. Omitting the age statement gives producers the opportunity to include younger whiskeys to their final product. This might also lead to a benefit for consumers when they see a price drop.
An extra advantage is that an age statement might reflect a quality experience for the consumer. But what does age say… Is it better? Is it worth a higher price? Not necessarily so. More and more producers are now moving to descriptions of their product, which will help the consumer make a better choice on what they are looking for.
Whisky production in Japan has been around longer than we think though. It began around 1870 although the first commercial production was in 1924 upon the opening of the country's first distillery, Yamazaki. It was built in a suburb of Kyoto, an area so famous for its water that the legendary tea master Sen no Rikyū built his tearoom there. The Japanese are known for being meticulous, so through the wood and water used might be different, the production process is the same as the Scottish process.
After this there still remains the question, Japanese or Scottish? Taste is personal, so there shouldn’t be a need to push you in one direction. Try both, explore and try to find what you like. Your choice and flavour profile are yours to be matched. Personally, I think the Scots offer more variety due to the different regions - I like a peaty whiskey from Islay.
