[NAFEX] berry sweetness: soil, sun or genes?

Yasi,

I think all of the things that you mention in the title of your post can significantly affect fruit flavor and sweetness.  While I'm not sure that soil pH necessarily affects fruit sweetness I think that can be ruled out here since you have said that the same berries have been sweeter in the past.  You mentioned that you'd been having cold wet rainy weather and I think that is probably the answer to the question there.  The sunnier the weather, the more sugars will develop in the ripening fruit.  Cloudy wet weather can cause even overripe fruit to never attain the levels of sugars that would otherwise be expected.

Hopefully you'll have a little more sun next year and your red raspberries will be as good as you remember them being in the past.
