Term (also known as bud or gemma in botany) for the youthful state of a new shoot. On vines, the eye is located in the leaf axils on the nodes of one-year-old shoots, which is why it is also known as the axillary bud or axillary bud. The so-called winter eye (winter bud) consists of lignified bracts that are stacked in several layers and envelop the primary, already pre-differentiated plants of the new shoot that will sprout the following year.
1 = Bud scales, 2 = bud wool, 3 = upper secondary bud, 4 = main eye, 5 = leaf scar, 6 = lower secondary bud, 7 = bark, 8 = bast, 9 = cambium, 10 = wood, 11 = pith, 12 = diaphragm (wooden bridge)

The glossary is a monumental achievement and one of the most important contributions to wine knowledge. Of all the encyclopaedias I use on the subject of wine, it is by far the most important. That was the case ten years ago and it hasn't changed since.
