Borçka Iron Apple

Borçka Demir Elması is a local apple variety belonging to the species Malus communis L., cultivated in the Borçka district of Artvin Province. Its sun-exposed surfaces exhibit a pinkish-red hue, while the shaded surfaces are green and sparsely speckled. The fruit flesh is crisp, with a weight ranging between 80 and 120 grams. Due to its low sugar content, its taste and aroma have a tart character. This apple variety bears fruit biennially, flowering in April–May and harvested in October–November. Adapted to high rainfall and humidity conditions, the Borçka Demir Elması can be stored for approximately nine months and is traditionally wrapped in dried corn leaves and preserved in structures known as serender.

Botanical Characteristics

The Borçka Demir Elması is classified within the species Malus communis L. and exhibits distinct features in terms of fruit color, texture, and flavor. The fruit has pinkish-red coloring on sun-exposed surfaces and green coloring on shaded surfaces, with sparse speckling. The flesh is crisp and weighs between 80 and 120 grams. High-Performance Liquid Chromatography (HPLC) analyses indicate that its low sugar content results in a tart taste and aroma.

Production Characteristics and Cultivation Conditions

The cultivation of the Borçka Demir Elması is adapted to the climate and geographical conditions of the Borçka district. Annual average humidity levels in the region range between 70.9% and 84.3%. Rainfall fluctuates between 56.7% and 142.1%, with minimum temperatures ranging from -12.2 °C to -1.2 °C and maximum temperatures from 37.3 °C to 41.7 °C. These climatic factors influence the apple’s low sugar content and extended storage capacity.

The trees exhibit a biennial bearing habit. Flowering occurs in April–May, and harvesting takes place in October–November. In orchard establishment, planting distances of 6x6 m, 7x7 m, or 8x8 m are applied on standard rootstocks, while 4x1.5 m spacing is used on semi-dwarf rootstocks. For nursery production, cuttings are taken from one-year-old branches of Borçka Demir Elması trees, and grafting by whip-and-tongue method is employed.

Harvesting and Storage

The Borçka Demir Elması is harvested within its designated geographical boundaries. Harvesting is carried out carefully using fruit-picking devices, and the collected apples are placed in baskets. Storage follows a traditional regional method: the apples are wrapped in dried corn leaves and stored in structures called serender, which are traditionally used for storing corn. This method helps regulate the fruit’s moisture content and enhances its durability. The storage life of the Borçka Demir Elması can extend up to approximately nine months.

Historical Sources and Geographical Indication

The Borçka Demir Elması constitutes an important component of the agricultural economy in the Borçka district. One of the earliest written records concerning this product is the 1927 publication “Şark Memleketlerimizden Artvin Vilayeti Hakkında Malumat-ı Umumiye.” On page 149, information is provided about apple trees in villages under Borçka district, describing this apple as “famous under the name Demir elması.” This evidence confirms that the origins of the Borçka Demir Elması date back to earlier periods and establishes its link to its geographical origin.
