Looking at the label, you can see three sets of kanji characters. The kanji on your right from top to bottom reads [ Kanzukuri-shinshu] winter brew new sake; sake that's brewed during winter and has not undergone maturation. The kanji in the center is the name of the brewer [ koshi no tsuru] cross over crane / rough translation. The last kanji on your left is [ honjozo] a premium sake. People with gluten-sentivity should be able to drink it. The kanji from the top coming down is [Muroka - Nama Genshu] so it's unfiltered, unpasteurized, and undiluted. How that translates into taste is that you get gamier bolder flavors that are fruity and clean.
