Capable of being tasted or having a pleasant taste.
From Latin 'gustare' (to taste) plus the English suffix '-able' (capable of being). This is a rare or archaic formation showing something can be perceived by taste.
Most foods are 'gustable' by definition, but the word reminds us that taste is one of our five senses—and in the age of artificial flavors, some chemists debate whether all 'tasteable' things are equally 'gustable' in the quality sense.
