Fuzzy Wuzzy was a Vine
February 2, 2017 2 Comments
One of the first things that a serious wine student will learn about Priorat is that it is one of the two DOCa regions in Spain, and that (its red version) is a hearty wine based around the Garnacha Tinta and Mazuelo (Carignan/Cariñena) grape varieties. Next, one might note the list of accessory varieties, which include some well-known international varieties (including Cabernet Franc, Cabernet Sauvignon, Pinot Noir, Syrah, and Tempranillo) as well as a grape known as Garnacha Peluda.
There it is: Garnacha Peluda; otherwise known as Hairy Grenache. The name peluda seems to come from the French pelut and means furry. How cute is that? The “hairy” part of the name refers to the small white hairs covering the underside of the leaf. Other terms used to describe this hirsutulous (botanical term for slightly hairy) characteristic include downy, wooly, fluffy, fleecy, and fuzzy. But they all mean the same thing: this leaf is hairy.
Garnacha Peluda, a mutation of Garnacha Tinta (aka Grenache Noir), is considered a unique variety and is often referred to as a downy-leafed variant of Grenache—which may make the inquiring mind wonder why a certain grapevine would mutate into such a form. The answer is that growing furry leaves is a biological adaptation. Biological adaptations are changes—structural (either morphological [able to be observed] or anatomical [internal]), physiological, or behavioral—that occur over many generations of plant or animal life in order to make the organism better suited to its environment and to improve its chances of survival.
The hairy-leafed variation of Grenache is a result of a morphological adaptation to hot, dry environments such as found in Priorat, as well as the Roussillon and Languedoc areas of southern France. (Note: in southern France, the grape is often called Lledoner [or Lladoner] Pelut.) The fuzzy layer protects the vine from water loss due to transpiration, helps shade the leaves, and reflects sunlight to help keep the plant cool. The hairy-leaf solution is one of several ways plants adapt to hot, dry environments. Others include small leaves, curled-up leaves, wax-coated leaves, woodsy stems, and green stems but no leaves.
Compared to its non-hairy cousin, Garnacha Peluda tends to produce wines that are lower in alcohol, lighter in color, and higher in acidity. The Garnacha Peluda grape is authorized for use in the following wines:
- Recommended/Principle variety in: Terra Alta DO, Languedoc AOC (as Lledoner Pelut)
- Accessory grape variety in: Empordà DO, Priorat DOCa, Terrasses du Larzac AOC (as Lledoner Pelut), Côtes du Roussillon and Côtes du Roussillon-Villages AOCs (also as Lledoner Pelut)
Vitis aestivalis varieties and native North American grapes native to the southwest, such as Mustang and Muscadine, are also likely to demonstrate the hairy-leafed adaptation. Many other plants have adopted this downy-leafed adaptation, including rosemary, sagebrush, oleander, buckthorn, magnolia or sycamore trees, potato, petunia, and lamb’s-ear.
Another famous hairy-leafed vinifera grape is Pinot Meunier. As meunier means “miller” in French, the grape is so-named for the layer of white, downy hairs on the underside of the leaves, said to resemble grains of flour (as produced by the town miller at the local flour mill). But as we now know, it is all about that morphological plant adaptation.
