We've waited longer than usual to harvest our blood oranges; waiting for a frost to nip them, which turns the skin a little reddish. The juice is delicious, and can be mixed with less intensely flavored (and colored) citrus for a beautiful fruit juice. The juice can stain. It's been really cold in Rainbow, but as I surveyed the farm today I found no actual frost damage. The mountains to the east are all snow capped. The drive into Temecula from my farm is spectacular with the mountains in the distance all covered in snow.
