Do the types of containers used change the taste of sake? YES!!
The fragrance and taste of sake are totally dependent upon the size and shape of the container in which the sake is served. There are three points to consider in choosing containers for serving sake.
A daiginjo type is best served in a glass made for white wine. A positive characteristic of this glass is that it has a wider opening for enjoying the bouquet. Aged sake is best served in a brandy glass.
If you would like to enjoy a thicker, richer sake (a junmai or honjozo type) and fragrance is less important to you, then use an earthenware sake cup. If you prefer freshness or coolness (a daiginjo or ginjo type) for drinking in the summer time, those sake are best served in a thin glass.
Japanese sake tastes better if the container is appropriate to the season. In summer, a thin carafe with ice in it will convey an atmosphere of coolness. In winter, the warmed thick pottery carafe referred to as a Tokkuri helps to impart a sense of warmth.
