Founder Varieties

My husband and I were talking about Cabernet Franc and what its possible influence would be on the flavor of a wine made from this grape. Our conversation then shifted to talking about Cabernet Sauvignon and the fact that the parents of that noble variety are Cabernet Franc and Sauvignon Blanc. That got me thinking about grape founder varieties and after a bit of searching on the Internet, I located an article written by Jancis Robinson in the Financial Times on October 2012, called "Where it all began..."
In this article, Robinson provides the names of the founder varieties and a short description:

VARIETY	DESCRIPTION
Pinot	Pinot is perhaps the best known of the founder varieties. It comes in many different-coloured mutations, of which Pinot Noir, Pinot Gris/Grigio and Pinot Blanc are well known. As Pinot Noir it makes hauntingly nuanced, generally light- to medium-bodied fruity reds, most famously in Burgundy but increasingly around the world. As Pinot Grigio, it is often devoid of any attribute other than popularity. Pinot Blanc is grown in Alsace, in south-west Germany as Weissburgunder and in Italy as Pinot Bianco.
Gouais Blanc	Gouais Blanc is an ancient eastern French variety almost forgotten until identified as “the Casanova of grapes” for the sheer number of its progeny. It has been banned for its low quality several times in France and survives there today only in one non-commercial vineyard in Haute-Savoie. The finest and most numerous examples are grown, as Gwäss, over the border in Switzerland although it is also known south of the Alps where several Piemonte growers cultivate it, some of them calling it Liseiret. It is also grown by Chambers in Rutherglen, Australia. It is light in weight and can have attractive citrus flavours.
Savagnin	Savagnin is best known under that name in Jura, eastern France, where its wines have an attractive nuttiness and a particular affinity for producing the local speciality, vin jaune, which tastes a bit like an alpine sherry. A popular synonym for the variety is Traminer, and the famous Gewurztraminer grape is the aromatic, pink-skinned mutation of it. As Traminer it is particularly popular in Austria, Alto Adige in northern Italy (birthplace of the name, not the variety), eastern Europe and Australia. It turned out recently that cuttings sent to Australia from northern Spain, and then disseminated to growers by the quarantine authorities as the fashionable north-west Iberian variety Albariño/Alvarinho, are in fact Savagnin.
Cabernet Franc	Cabernet Franc is more aromatic, graceful and usually lighter-bodied than Cabernet Sauvignon. In Bordeaux it is the third-most-planted red wine grape after its progenies Merlot and Cabernet Sauvignon, with which it is customarily blended. It is the principal grape of Chinon and Bourgueil in the Loire valley where its wines, usually 100 per cent Cabernet Franc, can be quite leafy and herbaceous, although in recent years the vines have tended to ripen more fully. It is widely planted, often as an ingredient in “Bordeaux blends”, but is valued on its own account in the American states of Virginia, New York and Washington.
Mondeuse Noire	Mondeuse Noire an ancient Savoie variety is either a grandparent or half-sibling of Syrah/Shiraz, which explains why one of its important synonyms is Grosse Syrah. It makes Savoie’s sturdiest, deepest-coloured reds. In California it was long confused with the north Italian Refosco dal Peduncolo Rosso, and vine DNA pioneer Professor Carole Meredith may be the only grower of genuine Mondeuse Noire in the state. She reports its wine is deeper and spicier than her Lagier-Meredith Syrah.
Garganega	Garganega is the main grape of Soave and was first mentioned in the 13th century. DNA profiling shows its close relationship to other important Veneto varieties such as Corvina and Rondinella, thereby confirming its local origins. Much more surprisingly, DNA profiling has shown that it is identical to the Sicilian variety Grecanico Dorato and an almost extinct variety as far away as Catalonia. It also turns out to have parent-offspring relationships with at least eight other Italian varieties including the most-planted white wine grapes in Sicily and Tuscany respectively. This is clearly a key grape, whose wines, if yields are restricted, can recall both lemons and almonds.
Nebbiolo	Nebbiolo is the most distinctive northern Italian red wine grape, most famously producing long-lived, scented but not heavy Barolo and Barbaresco on the Langhe hills of Piemonte but resolutely refusing, so far, to perform with much distinction anywhere else. The first mention of it in Piemonte dates from 1266. The succeeding centuries have allowed the development of several distinct clones such as Nebbiolo Lampia, but Nebbiolo Rosé, long thought to be a clone, has been shown by DNA profiling to be a distinct variety. Because Nebbiolo originated so long ago, it is not known whether it did so in Piemonte or in Valtellina to the north (it has so far been shown to have parent-offspring relationships with four varieties in each region). Its parents are almost certainly extinct.
Teroldego	Teroldego from Trentino in the far north of Italy is also extremely well connected. Surprisingly, DNA analysis has shown that Dureza from Ardèche, a parent of Syrah, is a full-sibling of Teroldego, and that both are grandchildren of Pinot. Teroldego is therefore an uncle of Syrah, as well as a grandparent of Refosco dal Pedunculo Rosso. Winemaker Elisabetta Foradori, who almost single-handedly brought Teroldego to international attention, must be delighted by this news. The variety had been in danger of being abandoned on account of the high acidity of its wines. It needs low yields and careful handling to produce fine wine, but the Australian example below managed to win a trophy in the 2010 Australian Alternative Varieties Wine Show.
Luglienga	Luglienga is an ancient, pale-skinned table grape that is grown all over Europe, but its wine is rare and not particularly interesting. The variety is more notable for its progeny, which include Prié and, more recently, the modern crossing Regner that was one of many bred by German plant breeders in the early 20th century to achieve high sugar levels.
Muscat Blanc à Petits Grains	Muscat Blanc à Petits Grains, the small-berried, pale-skinned Muscat, is the noblest of several Muscat grape varieties (which are the only ones whose wines actually taste like grapes). There is a host of different Muscat, Moscato and Moscatel varieties – in fact we identify 15 different ones in our book. This founder Muscat is grown all over the world, notably in northern Italy where it is responsible for the likes of Asti and other Moscatos, but it is so old and so widespread that we cite no fewer than 64 current synonyms, most of them beginning with M, but a host of them throughout eastern Europe, such as Romania’s Tamaioasa Alba, beginning with T. Muscat Blanc is especially good at making strong, sweet wines in southern France and Greece. It is still not known whether it originated in Italy or Greece.
Cayetana Blanca	Cayetana Blanca is a pretty basic white wine grape also known as Pardina and Jaén Blanco in Spain and Mourisco Branco in Portugal’s Alentejo on the Spanish border. It is closely related to a number of Portuguese varieties, and to the dark-skinned Juan García that is responsible for some fine reds in north-west Spain.
Rèze	Rèze---only a few hectares of this very ancient alpine variety, first mentioned in Switzerland’s Valais region in 1313, are grown commercially today, at one time it was more widely cultivated. DNA profiling suggests that it was once grown in the Savoie and Jura regions of France too – and my co-author José Vouillamoz had established that it has a parent-offspring relationship with at least five Swiss or Italian varieties and may also be related to the Piemonte’s Freisa. The few varietal examples that exist are delicate with green apple aromas.
Tribidrag	Tribidrag is also known as Crljenak Kastelanski and Pribidrag in Croatia, Primitivo in Puglia and, most famously, as Zinfandel in California. This ancient variety migrated across the Adriatic to Puglia and thence to California – probably via nurserymen in Vienna and New England. Since its origins have been definitively identified as Croatian, it has been enthusiastically planted there, with the total number of known vines having mushroomed from 20 to more than 200,000. The Zinfandel connection also halted a widespread decline in the area planted with Primitivo in Italy, particularly in the western Salento peninsula in Puglia. But most of the world’s plantings are to be found in California, where it is the second most popular variety after Cabernet Sauvignon. Some of these vines are 100 years old in some of the world’s oldest vineyards. Wines vary from syrupy pale pink “White” Zinfandel to spicy, long-lived relics of the state’s early Italian immigrants.

All of this information in the above table was used in the book written and researched by Dr. José Vouillamoz, Jancis Robinson, and Julia Harding called Wine Grapes - A complete guide to 1,368 vine varieties, including their origins and flavours. This is a good reference to have.
