Grapefruit from Dalat, Vietnam has become a popular but expensive snack due to its high quality and limited supply. The fruit is more expensive in the south than the north during its harvest season, and even more expensive off-season. Despite the high price, the unique smell and taste of the Da Lat grapefruit make it a hot-selling item. The unpredictable weather in Dalat also contributes to the fruit's high price and limited supply.
