Early in the season the fruit may be green on the outside but perfect on the inside and ready to eat. We can tell by pulling fruit samples from the groves to check the fruit's color and sugar level. Later in the season the fruit turns yellow or gold on the outside and this can also be a sign of maturity. Texas grapefruit often has an orange color that includes patches of a pinkish blush....almost like it has been "kissed by the sun". Avoid fruit that is lumpy, which can indicate the fruit has over-ripened. Select citrus that is heavy for it's size, that's an indication of its juiciness.
