Re: ROT IS GOOD and I know you know it!
That is what I was saying... side by side a low brix apple rots and attracts bugs flies, you name it as they are attracted to the rot. The high brix apple dries some,completely if I let it (still very yummy), however it does not attract bugs and flies... I have done this and have seen it for myself.
Low brix produce will send signals out from the store produce counters waiting to be sold. Sometimes it is easy to tell, however as you have stated, due to the "spraying" and/or irradiating of "conventional" produce quality becomes much harder to spot by sight (at least for me).
Low brix = little to know real taste or flavor
High brix = lots of taste and flavor
Follow your (taste) buds :-)
Trapper is right, one does not need a refractometer to do this... but it helps if you are not familiar with what high quality produce should smell, taste and look like.
After using a refractometer for a while you can learn (train yourself) to sight buy good, high quality, great tasting produce. If, you are now unable to recognize high brix produce by sight, the refractometer is an inexpensive, invaluable "training" tool that helps one to learn how to pick out better produce by sight and touch/vibrational feel.
My wife is always amazed at the produce I pick out now... she takes it to work with her at times and EVERYONE wants to know where it comes from (sometimes an organic garden or privately owned organic fruit trees); it is that good that their bodies naturally crave it.
I have about a bushel of lemons left that I had picked a month and a half ago in the refrigerator; every last one of them still looks and tastes (had one this morning) like I just picked them. Perfect...
