This variety, in my opinion, is the best of the pink grapefruit in both taste, and color. At Deer Creek Heights Ranch, the fruit is produced with a deep scarlet color inside and a pink/yellow/sometimes green outside. The skin is thin and very smooth. The taste is sweeter than other pink grapefruit and is testing 10 points of sugar in December. We have found that the bitter taste associated with grapefruit is not found in the Star Ruby. Its origin is in Texas, but our test block has shown that the hot California summers and loam soil produces a really outstanding and very juicy fruit.
