Buying & Storing Tips

While choosing grapefruits, you don’t have to worry about any type of skin discoloration, scratches or scales. Any such defect in physical appearance of the fruit will not have any impact on its taste or texture.
If you want to identify the rotten or the decayed variety of grapefruit, look for overly soft spots or areas that appear water-soaked. Such alterations change the general flavor of the fruit, making it bitter.
In case you are looking for varieties that have a higher concentration of juicy flesh, then go for the ones that are heavy for their size. This usually indicates that they have thin skin and fleshy pulp.
The consistency of a grapefruit should be firm. However, when mild pressure is applied, they should be slightly springy.
The best season for the purchase of grapefruits is from the onset of winter till the spring season.
To get a higher dose of antioxidants in your grapefruits, select the ones that are fully ripened.
If you want your grapefruits to be juicier, place them in a warm environment. This way, they can be stored for about a week. But if you want to keep them for a longer period, say about 2 to 3 weeks, then store them in the refrigerator. This will keep them crisp and fresh.
