Pleasantness Index PI: wine is pleasant when its taste truly recalls (with consistency, balance and integrity) the taste of the fruit it is created from. This is the reason why Quality Index and Fructosity Index are two ways to say the same, a value that shall be obtained judging and adding together the three fundamental organoleptic parameters, Consistency (C ), Balance (B) and Integrity (I).
Consistency (C). it represents the aggregate of wine’s compositional substances, resulting in the quantity of sensations involved in the tasting. The higher is the amount of grape produced by a vine, the lighter that wine’s consistency will be.
Balance (B). a wine is balanced when its sweetness equals its acidity and eventual bitterness’ sum. Vice versa, the wine is unbalanced when one of the three tastes prevails.
Integrity (I). A wine’s taste is integer when its constituent fruit’s taste can be sensed in its neatness and freshness. A wine whose tasting reveals no negative characteristics shall be considered neat; negative means not originating from the fruit as sulphurous smell or flavour, vinegar, dairy or over-ligneous aromas, etc. A wine’s freshness is given by its unoxidated flavours and aromas, being oxidation the cause for rancid, caramelized and Marsala-like sensations, not proper of the harvested grape.
Retail Price/Value Index (RPI): it expresses the relation between Pleasantness Index (PI) and Retail Price (RP) for a 0,75 bottle. It is a scalar intensive measure, rated on a decimal scale. The RPI increases at the PI increasing and it decreases at the 0,75 lt bottle’s RP rising. A wine whose PI is valued sufficient (PI=60) will score a sufficient RP value (RP=6) if sold for no more than 5,16€. A wine whose scored PI is that of a Fruit-Wine (PI=84) will be evaluated as sufficient in the RP index (RP=6) if the retail price stays under 38,73€.
Quali-Quantitative Index (QQ): It expresses the relation between a wine’s PI and that wine’s number of produced bottles. It is a scalar intensive measure, rated on a decimal scale. The QQ index rises both at the rising of the PI and the number of produced bottles. A wine whose PI is valued as sufficient (PI=60) needs a production of at least 60.000 bottles in order to have a sufficient QQ score (QQ=6). A Fruit-Wine (PI=84) has a sufficient QQ score (QQ=6) being produced in at least 3.000 bottles.
Total Quali-Quantitative Index (TQQ): it expresses the relation between a winery’s average IP and the total number of bottles it produces per year. It is a scalar intensive measure, rated on a decimal scale. The TQQ index is directly proportional to both the average PI and the total amount of produced bottles, obtaining the latter by adding together the number of all the definitive tasted wines’ produced bottles. A winery whose average PI is sufficient (PI=60) can get a sufficient score in the TQQ index (TQQ=6) with a production of at least 1.000.000 bottles per the year. A winery whose average PM is that of a Fruit-Wine (PI=84) shall produce at least 50.000 bottles per year in order to be valued as sufficient in the TQQ index (TQQ=6).
Purchasability Index (PUR): It relates a wine’s PI, its Retail Price referred to a 0,75lt bottle and the number of produced bottles. It is a scalar intensive measure, rated on a decimal scale. The PUR index increases at the PI’s increment, it decreases if the retail price grows and again it raises with the number of produced bottles. A wine whose PI is valued as sufficient (PI=60) shall be produced in at least 60.000 bottles and it shall be sold for no more than 5,16€ in order to reach a sufficient PUR score (PUR=6). A Fruit-Wine (PI=84) will get a sufficient PUR score (PUR=6) if the production is of no lower than 3.000 bottles and the retail price is no higher than 38,73€.
