Back A unit used to measure the length of time a wine's flavour lingers on the palate. It is measured in seconds. One second = one caudal. Zero caudal therefore marks the precise moment when the taster spits out or swallows the wine. In this measurement, only the intensity of the lingering aroma is taken into account, without the basic flavours of sweetness, acidity, bitterness, astringency and any salinity. The measurement of caudalies ceases as soon as the perception of aromas disappears. To get their bearings, beginners will learn, with practice, how to stop counting caudalies at the right time.
