Term (also young wood) for the new, green shoot of the vine. Grapes are only formed on the one-year-old wood, which is why they are also called fruit rods or fruit shoots. They do not begin to lignify until they are fully ripe in late summer or early autumn, but this is not completed until the beginning of winter dormancy. This can be recognised by the smooth bark and the clearly formed winter buds (winter eyes). The winter bud already stores the information for a new shoot and the fruit set for the next vegetation cycle. The winter buds then break open in late spring at budbreak and grow into new shoots or the new one-year-old wood. The basic shoot then becomes the two-year-old wood with slightly thickened wood and often lighter-coloured bark that is already showing the first cracks. Perennial wood becomes darker and harder with a cracked, gnarled and frayed surface. See in detail under eye, as well as under 1-2-3 rule and a list of relevant keywords under vine.

I have great respect for the scope and quality of the wein.plus encyclopaedia. It is a unique place to go for crisp, sound information on terms from the world of wine.
