mrtexas, I completely agree with you. I've tasted a difference in taste between limbs on the same tree on the same side on my own tree ! On another person's old tree I noticed a huge difference for the worst for one year to another. Same tree had produced a best in show years before. When I 'found it' the fruit was excellent. Best I've ever had. The next year or so the tree and fruit looked fine but the taste was average at best from the same side. It was a Browns Select. Water, fertility, weather including temps and both sunshine and cloudy days can all play games with our minds ! Like you said 'age of tree and growing conditions'. Tom
