A friend in Houston has a sweet white marsh grapefruit, the sweetest grapefruit I've ever tasted. It tests out at 15-16 brix. I've grown marsh and duncan myself and never had them that sweet or this early by December 1. It is not a fluke either as the fruit was just as sweet last year. His tree is mature and was purchased at a Master Gardener Tree sale years ago. Satsumas are testing out around 12 brix now around here.

What type is marketed as "Sweetie", Oroblanco? I see these for sale at the grocery store but I think they are awful tasting. I don't know if I've ever had a store bought Marsh, ...only a runt I picked from my tree last year. I am looking forward to trying it next crop.
A grapefruit tree has to get some age to it before the tree starts producing high quality fruit. My in ground Marsh grapefruit tree is now 7 years old, and still produces quite sour fruit. I remember on the old forum, Dr. Malcolm Manner posting the very best grapefruit he ever ate was picked off a 25-year old Marsh grapefruit tree growing on the grounds of Florida Southern College..

Of the white grapefruits, I like Sweetie best. No bitterness films and low acidity. For the sweetest taste the fruit should hang for a long time on the branch until it falls The best quality fruit in my conditions is obtained on the rootstock pummelo or panderosa lemon. The fruit on the rootstock of trifoliate smaller in size, ripen late, high acid and resinous taste
Got another 5 gallon bucket of 17+ brix marsh white grapefruit today. Thanks Bill Arendt. Never tasted a grapefruit before way sweeter than an orange! Wish I could drink the juice but blood sugar is too high already. I will savor every one I don't give away! Also got some budwood. Will bark graft it to an existing tree in the spring. Store in the refrig until then. Often in Houston grapefruit will start to grow in January so picked dormant wood today. If I have to wait for this sweet I also like the typical white grapefruit.
17+ brix is not a typo. I bought a brix refractometer and tested it myself. These grapefruit are the sweetest citrus I have ever tasted.
This is not oro blanco. It has the typical grapefruit bitterness in the section membranes. Oro blanco and melogold aren't grown much in Texas. I have tasted oro blanco. The skin here is very thick.

Phil, how old is your Marsh Grapefruit tree? You give me hope for my new tree. This years crop from my Marsh was more bitter than sweet. As I have posted before, Dr. Michael Manners of Florida Southern College once posted ...."The very best grapefruit I ever tasted was a Marsh Grapefruit picked off a 25 year old tree.
Laaz, that true for Colorado. However, the Marsh grapefruit is growing in the ground inside a greenhouse. Night time temperatures never fall below 55-F, and day time temperatures can be anywhere from 60 to 80 during the coldest winter months. Summer is of course warmer all around.
I too, recently tried Bill Arendt's white grapefruit that Mrtexas spoke of and can attest to their excellent flavor. Amazing fruit. My in-ground, 7 year old Rio Star is improving,year over year in quality. Looking forward to future crops. The first few years predation by neighborhood fruit smugglers (thieves really) helped themselves but the fruit was smallish and quite sour which has deterred them subsequently. They have left the tree alone since then.
