Fruit Fact: Adersleber Calvill, a variety of apples

German Calville style apple that stores really well and features a nice, spicy aromatic flavor.

Variety Background:

Most Common Name: Adersleber Calvill
Species: malus domestica
Synonyms: Lichtshardts Apfel
Origin: Adersleber Calvill originated in the Adersleber monastery in Oschersleben, Saxony Germany in the 1830's, credited to Lichtshardt, a gardener in the monastary at the time. The exact pedigree however is uncertain; some source claim it's a chance seedling, others claim it's a Calville Blanc D'Hiver and Gravenstein cross. Judging from it's blooming habits, flavor and shape, the latter is most likely the correct pedigree.
Patents or Trademarks: None

Fruit:

Description: Beautiful large, yellow-green apple with handsome orange-red flush, classic calville shape with large ribs forming a pentagonal shape when viewed from above the base, less pronounced from the calyx side. Similar in color and appearance to calville blanc d'hiver, however, much larger.

Flavor and tasting notes: Very refreshing, sprightly aromatic and spicy apple with firm flesh. Retains high quality flavor for a long time in storage. Highly esteemed in Germany.

Adaptation:

Early bloomer and medium chiller, very suitable for Central California. However, dry soil weakens the tree and renders the apples mealy, so it's important to keep it properly irrigated. Not recommended on dwarf rootstocks, especially in California. Prefers cooler, coastal locations, most likely not a candidate for the hotter districts like the Central Valley or Inland Empire.

Bloom Time Rating: F8

Growth Habit:

Heavy spurrer and comes into production very early. A prolific producer with a tendency towards a weeping, limbertwig habit. Due to the heavy bearing, this variety is a natural dwarf when left un-pruned as all the branches will bend down and limit upward growth. To get a decent height on the tree, a good dose of Winter/early Spring pruning is advised.

Vigor: T2

Harvest, storage and consumption:

Ripens in September and stores until April provided it's picked as late as possible and isn't growing on dry ground, otherwise it tends to go mealy quickly.

Begin of Harvest: early Sept
End of Harvest: mid Sept
Stores Until: mid April

Usage:

A fantastic high quality dessert apple, but looses its flavor when cooked, even though it retains its shape well. Therefore not recommended for cooking.
