Black Beaut Plum is just one of the many types of plums available in the summer months. It is a drupe, and as with all drupes, has a large pit or stone inside, and soft succulent flesh. Black Beaut Plums have a deep purple/black skin, and juicy dark red flesh. It is considered one of the most popular of the plums. T

Plum sizing is based on the maximum number of plums in a 10-pound sample of fruit. Using this system, it is easy to figure the number of plums per pound and the number of plums in the industry's standard 28-pound volume-fill box by using the following conversion:  Size = Number of Plums per 10 pound sample    Plums Per Pound = Size 10 Number of Plums per 28 lb. box = Size x 2.8
The most common plum sizes are 30, 35, 40, 45, 50, 55, 60, 56 and 70.

Plums must be kept out of the cooler and held at temperatures between 51 and 77 degrees F to properly ripen to juicy, sweet perfection.
Fruit should be kept in this temperature range until flesh firmness has been reduced to 4-5 psi for plums. At this point, the fruit has reached the "transfer point" and can be safely shipped to operators without bruising.

For the best quality and ripest plums keep tree fruit out of the cooler. You can actually damage fruit by storing it between 36 and 50 degrees F--the
temperature of most commercial warehouse coolers. Fruit stored in this "killing range" can develop "internal breakdown," becoming mealy, dry and tasteless.
