An exploration of South Tyrolean Pinot blanc wines and their quality potential in vineyard sites across a range of altitudes


Aim: Pinot Blanc is the third most planted white wine grape in northern Italy’s region of South Tyrol, where small-scale viticultural production permits the examination of the wine’s diverse expressive potential in a small area across a wide range of climatic variables. This study aimed to explore the qualitative potential of Pinot Blanc across a range of climatic variation leading to site-specific terroir expression in a cool climate region.

Methods and Results: Eight Pinot Blanc vineyards with individually unique terroir along the Adige Valley were chosen and monitored over the course of three years and resulting wines underwent chemical and sensory analysis. Selected quality-defining parameters were compared to four defined temperature classes and multiple harvest dates. Temperature class had a mild effect on aromatic expression of Pinot Blanc wines, with organoleptic perception of cooler sites being characterized by higher acidity and citrus aromas, while warmer sites had more prominent pear and banana aromas. Different harvest dates had a stronger impact on cooler sites, while warmer temperature classes showed little difference between time of harvest.


Vineyard site temperature is less of a principle driver of wine expression in Pinot Blanc than time of harvest, which has a stronger impact on cooler vineyard sites, where achieving a certain technical ripeness is paramount to producing high quality, typical wines. To mitigate the effects of climate change, it may be beneficial for warmer wine producing regions with narrowly defined typicity and limited climactic variation to employ earlier harvest protocols. 

Significance and Impact of the Study: Mountainous regions provide the opportunity for agricultural activity at higher altitudes, where cooler conditions and earlier harvest dates could potentially mitigate the deleterious effects of rising temperatures on grapevines and preserve the typical organoleptic qualities associated with wines from these regions.

Significance of factors making Riesling an iconic grape variety

Riesling is the iconic grape variety of Germany and accounts for 23% of the German viticulture acreage, which comprises 45% of the worldwide Riesling plantings. Riesling wines offer a wide array of styles from crisp sparkling wines to highly concentrated and sweet Trockenbeerenauslese or Icewines. However, its thin berry skin makes Riesling more vulnerable to detrimental environmental threats than other white wine varieties.

Winemaking techniques and wine tasting methods at the end of the Middle Ages

Les pratiques de vinification et de dégustation du vin sont souvent perçues, à travers un discours marketing très puissant, sous l’angle d’une tradition millénaire qui perdure depuis le Moyen Âge. En Bourgogne, il est courant de rattacher les racines de ces pratiques à l’activité des institutions ecclésiastiques qui possédaient d
