Daiginjo (???) is super premium sake (hence the �dai,� or �big�) and is regarded by many as the pinnacle of the brewer's art. It requires precise brewing methods and uses rice that has been polished all the way down to at least 50 percent. Daiginjo sakes are often relatively pricey and are usually served chilled to bring out their nice light, complex flavors and aromas. Junmai daiginjo is simply daiginjo sake that also fits the �pure rice� (no additives) definition.
