Sake is in general a light beverage. Even compared to the lightest of wines, sake is quite light. It can range from unassuming, quiet, light, airy and delicate on one end, to full-bodied, fat, heavy, thick, and ripe on the other. There are sake that are smooth and airy and sake that are rich and creamy. But there are very real differences between one sake and another in terms of the presence they command in the audience of your palate.
Some sake is very straightforward.
Here ya go. What you taste is what you get. This can be very reassuring and sometimes exactly what you want. For example, if the conversation is likely to be lively and loud, the chances that anyone is going to meditatively ponder the layered contours of the sake you are tasting are rather infinitesimal. Simple but solid sake is what you need.
