Junmai Daiginjo Sake is brewed using only rice, water, yeast and koji. There are no other additives. To qualify as a Daiginjo, the rice grain must be milled to 50% or less of it’s original size.
Daiginjo Sake is the same as Junmai Daiginjo except a small amount of distilled brewer’s alcohol is added to the sake to achieve different flavor profiles.
