There have been several factors that have contributed to shortages of Prosecco in recent years. One major factor is the increasing global demand for Prosecco, which has significantly increased production over the past decade. However, in some years, adverse weather conditions such as frost, hail, and heavy rain have caused lower yields and reduced the amount of Prosecco that can be produced.
Additionally, in 2019, the Italian government introduced new regulations that tightened production standards for Prosecco, which led to a decrease in the overall amount of Prosecco that could be produced. This decrease in production, coupled with rising demand, has contributed to shortages of Prosecco in some markets.
Finally, the COVID-19 pandemic has disrupted global supply chains and caused shipping delays, which has further impacted the availability of Prosecco in some regions.
Overall, a combination of factors, including increasing demand, weather conditions, production regulations, and the pandemic, have all contributed to shortages of Prosecco in some markets.
