In Vietnam, off-season avocados are in high demand, with prices soaring up to 70,000 VND/kg due to their limited quantity and the difficulty in ripening them. Sellers are reportedly selling 2-3 quintals of these avocados daily, despite the risk associated with ripening them. Experienced sellers use fermentation techniques to aid the ripening process. However, some sellers have reported losses due to the inability to ripen the avocados, resulting in waste. Customers are advised to buy from reputable sellers to avoid purchasing unripe avocados.
