Rio Red Grapefruit

Just as the Ruby Red Grapefruit was a mutation from the original grapefruit trees, the Rio Red Grapefruit is a mutation from the Ruby Red. The Rio Red has a deeper color than the Ruby Red, it is less acidic, and is sweeter. The Rio Red Grapefruit is also rounder in shape than most grapefruits as well as being juicier than the other variants. This is a long way from the first grapefruits that were found to have whiteish flesh, very acidic taste, and extreme tartness.

Rio Red Grapefruit Buying Guide

If you’re in the market for Rio Red Grapefruit, look for fruits with perfectly yellow skin with a pink blush on it. Choose fruits that feel heavy for their size, the heavier the fruit, the more juice it has inside. Minor scratches and marks on the surface are no problems because as one grower said, these are “beauty marks” from when the fruit rubs up against the branches due to the wind.

While minor marks and scratches are okay, avoid Rio Red grapefruits that are bruised or that has soft spots as these might be indications of mishandling or decay.

Rio Red Grapefruit Production & Farming in Texas

Almost all commercial Rio Red Grapefruit production is located in the Rio Grande Valle Area. The extremely fertile soil coupled with the sheltered climate provides the perfect conditions for growing Rio Red grapefruits. In fact, grapefruits that don’t have red flesh have been banned in Texas since 1962, so all of the grapefruit being sold and grown in Texas are descendants of the original Ruby Red grapefruit.

Today, less than 10% of total grapefruit production occurs outside of the Rio Grande Valley region. Most of the production outside of the Rio Grande Valley region is by small organic farms that supply local markets, and farmers’ markets. Some of these farms also offer “pick-your-own” or “u-pick” services where you can get the freshest grapefruits straight from the trees.

Pesticides:

In the latest release of the EWG’s guide to pesticides in produce, the grapefruit has been taken out of the Clean Fifteen list and is now located somewhere in between the clean and dirty lists. This would mean that more and more pesticides and chemicals are being used on non-organic grapefruit trees.

While the thick rind of the grapefruit protects the inner flesh from contamination, it is best to just fully avoid the contamination by purchasing organic Rio Red grapefruits.

Geography:

The Rio Red grapefruit is a cold-hardier version of the original Ruby Red variant. It thrives in USDA hardiness zones 10 through 12. It requires loamy soils or sandy loam soils to grow well, as well as full sun to be able to bloom and fruit properly. The Rio Red variety can survive outside of the Rio Grande Valley Region due to its cold hardiness and only a little cold protection is required.

Packaging:

Rio Red Grapefruits are commonly packed in corrugated paper board boxes, molded pulp trays, and wooded boxes. They require no special protective packaging as the rind is kind of thick and protects the fruit rather well.

Enjoying Rio Red Grapefruits

Rio Red Grapefruits can be enjoyed by slicing them in half and then scooping out the flesh with a spoon or a specialized grapefruit spoon. They can also be peeled like an orange, but be prepared to get messy as Rio Red grapefruits are super juicy.

Storage:

Rio Red Grapefruits can be stored on the countertop at room temperature for up to a week without losing much quality. They can also be stored whole inside the fridge for up to a month and a half without any noticeable degradation.

Note: When storing them inside the fridge, make sure not to crowd them as crowding them can cause mold formation.

Cooking:

Rio Red grapefruits are best when consumed raw. They also make excellent additions to fresh salads and fruit salads. The flesh of the Rio Red Grapefruit is also great as toppings of different desserts and dishes. Rio Red Grapefruits are also commonly broiled with butter and cinnamon. The peel of the grapefruit can also be candied, but make sure to use organic grapefruit when candying peel to avoid consuming pesticides that might be present in commercially grown grapefruit.
