This month, in our glasses, we are going again to compare two white wines, with a tasting by contrast featuring two geographically distant grapes. It is not the first time we are going to examine grapes typical in distant places, a characteristic allowing us - among the many things - to understand the influence of different climate conditions. Differences between the two grapes, of course, are not only depending on the respective environment in which they are cultivated in, indeed - and in particular - on their specific qualities. These differences will let us understand better the two grapes of our tasting, because of the evident contrast existing in their wines. This month we will evaluate Cortese - a white berried grape from Piedmont, in particular from the Southern area of the region - and Inzolia, one of the glories of Sicily and also found in Tuscany.

 Cortese is the variety used for the production of the famous white wines of Gavi - in province of Alessandria - one of the areas of Piedmont ranking as DOCG, Denominazione d'Origine Controllata e Garantita (Denomination of Controlled and Guaranteed Origin). Cortese is also found in other areas of Piedmont, however it is Gavi to represent the area producing the best expression and notoriety. Inzolia, the variety we will compare to Cortese, is typically associated to Sicily - its homeland - in particular the Western area of the island. Used for the production of some Marsala styles, the grape from Sicily has widely proven to make white table wines of remarkable character and elegance. Inzolia is also found in the territory of Tuscan Maremma and Elba island, here known as Ansonica. Both Cortese and Inzolia have a good versatility and are used with different wine making techniques, from inert containers to casks and, in case of Cortese, good results have also been obtained in sparkling wines making.

 Cortese is a white berried variety of Piedmont and it is used in the production of many white wines of the region, of which the most famous one certainly is Gavi. This variety is mainly found in the Southern territory of Piedmont and it is also used for the production of some white wines of Colli Tortonesi and Monferrato areas. Outside Piedmont, Cortese is found in Veneto, in particular in the territory of Custoza and used for the production of the same name white wine. In these lands Cortese is known as Bianca Fernanda. Cortese is also found in Lombardy, in particular in the territory of Oltrepo Pavese. Like already said, Gavi is the area in which Cortese has its best expression - also in terms of quality - thanks to the conditions of the territory and the many wine styles used for the production. In this territory - in fact - producers have proven the good versatility of Cortese, by making wines in inert containers and wooden casks, last but not the least, sparkling and sweet wines.

 The origin of Cortese grape is not clear, also because of the lack of historical and written proofs which could let us understand and define its origin better. The most supported theory wants Cortese to be originated from the province of Alessandria. This theory is also supported by the evident reason of the high concentration of Cortese vineyards found in the territories of Gavi and Tortona, areas in which Cortese wines have their best expression. It is known for sure, thanks to documents of the past, Cortese was already common in Piedmont since 1700s. It will be at the end of the 1800s we will have a more complete and better description of Cortese, in particular thanks to the work of professors Pierpaolo Demaria and Carlo Leardi dedicated to the grape varieties of the territory of Alessandria. Because of phylloxera, Cortese was progressively replaced in vineyards by other varieties, something which significantly compromised its presence in Piedmont. It will be only in the 1950s, also thanks to the interest shown by the famous writer and director Mario Soldati, producers will be interested in Cortese again and resumed making wines from this grape.

 Today Inzolia is, with no doubt, one of the most important and interesting white berried grapes of Sicily. After having been used, almost exclusively, for the production of Marsala and Vermouth, today Inzolia is mainly used for the making of table wines. Thanks to some producers, this Sicilian white variety has given excellent results in making interesting wines, also having a remarkable longevity and class. Inzolia is protagonist in many Denominazione d'Origine Controllata wines of Sicily, in particular in the provinces of Trapani, Agrigento, Caltanissetta and Palermo. It is believed Inzolia was introduced to Sardinia from Sicily and, from here, introduced to the territory of modern Tuscan Maremma, where it is known as Ansonica. In this territory Inzolia seems to confirm its special relationship with islands, by becoming known and common in Elba and Giglio islands as well.

 Inzolia is believed to be an indigenous grape of Sicily, however this theory is not supported by many. For some it is a variety of Greek origins and introduced to the territory today corresponding to Calabria and, from here, introduced to Sicily. For others, Inzolia was introduced to Sicily at the times of the dominion of Normans. The Sicilian origin of this variety is however the most probable, also supported by some genetic relations Inzolia has in common with other indigenous grapes of this island. This white berried variety has however proven, both in Sicily and in Tuscany, to make interesting wines, as well as having a good wine making versatility. If once this grape was mainly used for the production of fortified wines - such as Marsala and Vermouth - today Inzolia is the protagonist of elegant and interesting white wines. Inzolia however remains one of the great protagonists of Marsala wines, used in Oro and Ambra styles with Grillo, Catarratto and Damaschino grapes.

The color of Cortese grape in the glass

 Our tasting by contrast will have as protagonists wines produced with 100% Cortese and Inzolia, in both cases vinified in inert containers, preferably steel tanks. Choosing a Cortese wine is, like to say, very simple as we will pick a bottle coming from the most significant and famous territory for this grape: Gavi. As for Inzolia, we will choose a wine from its homeland - Sicily - however, as this grape is widely common in this island, differences can also be substantial according to the area. We will choose a wine made from 100% Inzolia from the Western part of Sicily, in province of Trapani, an area in which are found many DOC wines made from this grape. Among the many are mentioned Alcamo, Delia Nivolelli and Erice. On this regard, we should notice the production disciplinary for these wines provide for a minimum 85% of Inzolia, we will therefore make sure our wine is made with this variety only. The two wines will be served at a temperature of 10 °C (50 °F) in tasting glasses.

 Let's pour the two wines in their glasses and start our tasting by contrast. The first wine we will examine is Gavi, made with Cortese grape. Tilt the glass on a white surface and evaluate the color and transparency of wine at the base of the glass. Cortese shows an intense and brilliant greenish yellow color with a very high transparency, allowing a perfect vision of the object put between the glass and white surface. Nuances of wine, observed towards the opening of the glass, where the liquid mass is thinner, show a greenish yellow color. Let's now pass to the observation of Inzolia: at the base of the glass we will see a brilliant straw yellow, sometimes having golden yellow hues as well. Also in this case, transparency is very high. Nuances of Inzolia show straw and greenish yellow colors. Let's now compare both glasses by placing them side by side: differences in color are evident and, of the two, Inzolia is the one usually showing a more intense and deep color.

 Two different grapes having different characters and, of course, giving distant wines. Not only divided by a long and substantial geographic distance but also - and above all - evident organoleptic and enological diversities. Differences between Cortese and Inzolia are evident in every organoleptic aspect. Cortese usually gives wines with fresh aromas and a body of moderate structure; Inzolia gives to the senses wines with a more mature profile and an evident fuller body than the grape from Piedmont. According to an olfactory point of view, Cortese expresses aromas of flowers and fruits, in particular apple, pear, plum, hawthorn and broom, usually followed by a pleasing hint of almond and mineral sensations. To the nose Inzolia too expresses aromas of flowers and fruits, however in this case they have an evidently “riper” character, with clean aromas of citrus fruits, as well as apple, pear and plum, to which follow peach and, sometimes, jasmine.

 Let's now proceed with the olfactory evaluation of our wines, starting from the wine produced with Cortese grape. By holding the glass in vertical position and without swirling, let's do a first smell, therefore evaluating the opening of the wine. From the glass are appreciated intense and clean aromas of apple, pear and hawthorn, evidently agreeable. Now swirl the glass, in order to favor the oxygenation of the wine and therefore the development of other aromas. The second smell completes the wine with aromas of broom, peach, plum, pineapple and, frequently, a pleasing almond aroma. Let's now pass to the examination of Inzolia's olfactory profile and proceed with the evaluation of opening. We will perceive intense and clean aromas of pear, apple and citrus fruits, frequently followed by broom, very agreeable. After having swirled the glass, let's do a second smell which will complete the olfactory profile of the wine with hawthorn, peach, almond, plum and, frequently, the elegance of pineapple.

 The next phase of our tasting by contrast will evaluate the gustatory aspect of the two wines. Just like in the previous phases, the first wine we will examine is Gavi, produced with Cortese grape. Let's take a sip and evaluate the attack of the wine, that is the gustatory sensations perceived at the beginning of the evaluation. In the mouth is perceived the pleasing crispness given by acidity, well balanced by alcohol, with a body which can be defined as average. In the attack can be perceived flavors of apple, pear and peach, confirming a good correspondence to the nose. Let's now pass to the evaluation of Inzolia's attack and take a sip of this wine. In the mouth is perceived, also in this case, the crisp sensation produced by acidity, properly balanced by alcohol and supported by a pleasing roundness, as well as a fuller body than Cortese. Correspondence to the nose is clearly good: in the mouth are perceived intense and pleasing aromas of apple, plum and pear, as well as almond.

 The last phase of our tasting by contrast will examine the final sensations left in the mouth by the wines after having swallowed them. The finish of the wine produced with Cortese is persistent, leaving in the mouth pleasing flavors of apple, pear and peach, frequently followed by almond. Moreover, we will also perceive the pleasing sensation of crispness certainly inviting us to appreciate the wine again. The finish of Inzolia is equally persistent leaving in the mouth sensations recalling pear, plum and apple, also in this case followed by almond. The sensation of crispness is also in this case very evident, however - compared to Cortese - the perception of body in more intense in Inzolia. On the other hand, the overall sensation given by Cortese is about a lighter wine however elegant and agreeable, characterized by a higher acidity and a roundness clearly lower than Inzolia.
