Verdelho Grape Variety Report


              Like many wine grapes today, Verdelho is a grape variety that is grown globally due to the economic value of this fruit; however, it is produced on a relatively large scale in only a few select areas.  The most traditionally recognizable wine from the Verdelho grape comes from the Portuguese island of Madeira off the coast of Morocco where it has customarily been wrought into a fortified medium-sweet, medium-dry wine with stonefruit aromas.   It is also grown in relatively significant amounts on the mainland of Portugal (specifically the Douro Valley in the north), western France in the Loire Valley, Spain, California, and Australia where the wine is truly beginning to thrive. 



Comparable to the dissemination of other grape varieties, it is widely believed that the Verdelho grape appears in various countries under different names, for example Italy.  It is possible that the grape originated in Sicily due to the presence of a grape in this region called Verdello that is almost identical genetically speaking to its Portuguese counterpart; the genetic variations would be accounted for by the quick evolution of grape vines and their adaptability to new environments. 
Regions with varied climates produce a vast array of Verdelho wine flavors from apricot to mango, apple juice, pineapple, and lemon lime all the way to white pepper.  As a fortified wine from Madeira, the product is medium-dry with a more pronounced citrus flavor, generally high acidic tang, and elevated alcohol content. A crisp and tart dry table wine emerges from Portugal. A sweeter, flower perfumed, and rather full bodied wine is produced in the Central Coast.  In this region, treatment with oak increases the wine’s longevity while at the same time boosting the grape’s aromatic qualities. 
Climates were weather is too warm can lead to an unpleasant fiery high alcohol content if the grape is picked too late and allowed to over-ripen.  Though if picked at the right time, a warm climate enhances Verdelho’s tropical flavors and allows the grape to thrive.  On the other hand, a cool climate enriches the herbal and citrus qualities of this variety.  A majority of internet sources label Verdelho as a grape that ripens early, though some argue that the more complex flavors are developed as the fruit is allowed to sit on the vine for a little longer in the harvest season.  
The Verdelho grape has become quite prominent in Australia where the wine made turns out dry to off-dry yet maintains a fruity richness.  The diverse climates across the country allow for as assorted collection of end products.  For example Langhorne Creek, Hunter valley, and Western Australia produce wine with a range of flavors.  Western Australian wine has been described as fruity, fresh, and “with a honeysuckle vein”.  Pineapple and guava flavors have been pegged as main descriptors for the Langhorne Creek region.  In contrast, Hunter Valley is noted for spiciness. 
The general characteristics of the wine tend to lean in the high alcohol and acidity range with very aromatic qualities.  Other common characteristics include a rich, spicy, herbaceous, and tropical nuttiness.  Since the grape tends to over ripen, wines from anyone other than a master of Verdelho can often be sugary, unattractive, flabby, fat, and broad.  The wines are hot with an alcoholic burn if picked too late.  However, the flavors of the grape mature later on in the season, so picking too early is not a fix for the overripe issues. 
Yet when picked at the right time, the end product can be a nice complex dry wine or even a softer fruitier product!  In this sweet spot range of the Verdelho grape, a slightly earlier harvest showcases herbs and lemon citrus, while the back end of the range highlights its rich and fruity characteristics.   The dramatic and expressive qualities of Verdelho discourage many winemakers from blending the grape; it allows a degree of invigorating acidity that is balanced with its fruitiness. 
Worldwide in 1980 the hectare coverage of the Verdelho grape was roughly at 100.  In fifteen years that number grew to 1,500 hectares globally.  Though the number is dated by eight years, I could not find a more recent statistic.  The production of this grape has decreased in Madeira where is had traditionally been a huge success, but Australia has been experimenting and widely succeeding with Verdelho. 
The fruit itself is relatively hard and small with an oval shape.  The clusters are a golden yellow color and the skin is rather thick.  The grapes are high in acidity preferring rocky soils in warm dry climates.  Overall wine produced from this grape is a refreshing white that cleanses the palate and invigorates the drinker!
