sun and water play on the tste.
too much water , or not enough sun will inhibit the sweetness.
the youtube fruit tast guy (i forgot his name)
says they taste like strawberry nesquick.
midsummer and fall are best here, unless we get too much rain.
i had 3 small ones last fall, pretty sure they are all dead now.
the large one i had (15ft) died last winter around 27F.
