Balsamic vinegar, Modena, 50 years, Prestige Riserva Qualita 50, Casanova, 50ml

Step 1: harvest Grapes are still harvested by hand, according to tradition, selecting the best Trebbiano and Lambrusco di Modena grapes. It takes place in the months of September and October, when the ratio between sugar and acid is higher, and this is a very important stage in the production of Balsamic Vinegar of Modena, because the quality and integrity of the bunch before pressing is essential. The grapes are pressed using a "soft system" to avoid an excess of polyphenols contained in the skin, seeds and pips, which slow down the acidification process and could cause the product to be bitter. The must is then filtered to remove residual solids and impurities.


Step 3: Boiling Grape juice is boiled within 24 hours of pressing to prevent fermentation. It is cooked in an open steel cauldron, under which there is a furnace for 36 - 48 hours, up to °C. The boiled juice is left to cool and rest until the end of January.


Step 4: Aging The must is left to mature in wooden barrels which consist of nine wooden barrels with decreasing capacity,  from 180 to 10 liters, each made of a different wood (oak, cherry, ash, chestnut, mulberry, juniper, gum arabic ...) and only filled to 75% capacity. The barrels  are placed in the attic, because there the range of temperatures is greatest  (hot summer and cold winter). The barrels are open to allow the liquid concentration to evaporate naturally.  Aging is a  secret that is often passed down from generation to generation and therefore does not follow fixed rules. Each manufacturer proceeds according to their own experience gained over the years. The subsequent steps described occur during the aging period, which can last forever! 


Step 5: Pouring and topping up These two operations are related in the winter, when balsamic vinegar fermentation does not occur due to the cold. Pouring is the transfer of liquid from a larger barrel to a smaller one, and topping up is topping up the barrel. The first operation therefore always includes the second one, with the exception of the first cask called "madre = mother", which is the largest cask into which the immediately boiled juice is put. olfactory, visual and taste tests, clarity, aroma and taste are performed on each barrel. They are used in transparent glass containers and into which vinegar is poured through a glass tube. For visual analyses, it is preferable to use candlelight to assess backlight color, density, and clarity. Olfactory parameters include intensity, persistence of aroma and acidity, while taste is analyzed for intensity, taste, harmony between sweet and sour and acidity. It is better to use a porcelain spoon, where there is no change in taste. These tastings are done between meals and different tasters compare the results to ensure optimal quality
