In terms of flavor, the acidity has decreased, so has the sweetness, and of course, the flavor has also declined, so can it be Lim?

The answer is. Yes, it still has a fruit flavor like orange juice at the entrance, but it is dominated by a single aroma, that is, the main flavor of the bean itself is still outside most of the flavor has been lost. When the temperature drops, the fruity flavor is obvious. The flavor and taste are also better. It's obviously sweet.
