Roter Mond
type: Culinary, Cider, Dessert, Jelly, Juice, Sauce
synonyms: Marketed as Weirouge. Also known as Blutapfel (Blood Apple). Usually referred to as Red Moon in the English-speaking world, but the name is owned and used by a multinational organization which markets and distributes a variety of apples, particularly several red-fleshed cultivars.
summary: A cider and dessert apple developed in Russia during the early 1900s. Marketed as
Weirouge . Used commercially for making juices, often blended with sweeter apple varieties for cider.
identification: Small tending to medium size, round-conic to round-cylindric, often somewhat lopsided. The skin is completely washed deep red. The calyx is rather large and partly open, set in a narrow, moderately deep basin. The stem is short, extending barely to the height of the shoulder, medium stout and set in a narrow, medium deep cavity.
characteristics: The flesh is intensely red, but becomes pink and even white around the core. Crisp. Juicy and sweet-tart when fully ripe. Does not brown when exposed to air.
uses: Juice, apple sauce, jelly and dried apples. For most purposes, plan on adding sugar to the mix since these apples are rather tart. Best left to mature for a few weeks in storage before using, to allow the sugars to gather. Makes a very red juice which is often mixed with sweeter juice varieties to produce a commercially marketable drink.
origins: Originated as an open-pollinated
RF: Niedzwetzkyana's Apple in the early 1900s by Russian horticulturalist Ivan Michurin at his experimental farm near Michurinsk in western Russia. A young tree answering to the description of Michurin's cultivar was found growing in a garden in Germany and taken to the Wissenschaftszentrum Weihenstephan für Ernährung, Landnutzung und Umwelt of the Munich Technical University in Freising-Weihenstephan (Germany). It was subsequently registered under the name Weirouge in 1997.
cultivation: Needs full sun and grows best in well drained soil.
progeny: RF: Baya Marisa is cross of Weirouge and an experimental clone. Released in 1997.
harvest: Late in the fourth period. For full benefit of flavour and sugars, the fruit needs to be left on the tree for the full term.
notes: The leaves and bark also show the characteristic red colouration of this variety. The red colouration of the flesh of this and other redfleshed apples is due to elevated levels of anthocyanins (tenfold that of other apples), which are valued as powerful antitoxidants. High levels of anthocyanins are also present in blueberries, cranberries, cherries, some grapes (both dessert and vinifera), chokecherries and açaí berries, to name a few.
