First Grapefruit Picked

DocHollywood 9b Central Tucson(USDA 9b)December 24, 2012

A grapefruit (ruby red) was accidently knocked off my tree. I decided to taste it. It was pretty sour. I am guessing that it is not ripe yet. My question is: How do you tell when the fruit of the ruby red is ready to eat? I have read on this forum that it is best to pick occasionally and taste. But, can you go by the color of the rind? I will attach a picture of the cut fruit showing the inside and the rind color. This tree was planted a year ago last month and has about 10 fruits on it this winter. I believe the ripening season is Dec to June. Thanks for any info you can give me on this.

I'm not as familiar with Ruby Red (I have Rio Red), but I think you still have a month or two to go, for the beginning of peak ripeness here in California. My Rio Red grapefruits are not coming into ripeness until February through June. And no, you cannot always rely on citrus skin coloring up. For the most part here in S. California, the skil will get fully colored by the time the fruit is ripe. But, if we have prolonged warm nights, you can still have a little green on the skin. Not so prominent with later citrus (like grapefruit), as they ripen when we tend to get our colder evenings, which helps to color up the skin. Patience, Grasshopper. You still have at least a couple of months to go to peak ripeness.
