We are pleased to announce that we are officially granted the patent for the "Methodology in Brewing Long Lasting Aroma and Character Sake", which is used to brew our "Ryu Sho Daiginjo" to be release in Hong Kong in August 2022.

 Maintaining the quality of exported sake is one the issue faced by all sake brewery, as it is very difficult the manage the temperature of the sake throughout the transportation process. One of Ryusho’s core value is to deliver high quality sake with elegant aroma and great taste to people of the world. To overcome this challenge, we have developed a new sake brewing methodology to bring our vision to reality. A difficult issue is maintaining the quality of exported sake is that it is difficult to control the temperature of sake during transportation. As one of Ryu Sho’s core value, our brand aims to create sake that has gorgeous aroma and deliciousness. We then have developed a new brewing method to deliver the sake in our vision to customers outside Japan without the quality being affected. With the assistance and support from the Brewing and Food Department of the Fukushima Technology Plaza - Aizuwakamatsu Technical Support Centre, we are granted the patent to our brewing methodology. Sake brewed using this method is characterized by its elegant aroma, well-balanced taste, and can be stored at around 15oC without any deterioration.
