Controlled Air Curing 

The 1990’s saw a major investment in temperature and humidity control for the curing of wrapper leaves, to overcome the unpredictable conditions in a conventional barn. This is air curing at its most refined, with optimum conditions replicated around the clock. The time it takes is naturally less, around 25 days. But there is still the need for constant vigilance and adjustment as the condition of the leaf develops – the more so, because the process now runs at full pace day and night.
