The Uttwiler Spätlauber is an apple cultivar from Switzerland , which is known since about 1750. The exact naming is important, because there are several apple varieties called "Spätlauber". Common to all Spätlauber apple varieties is that they have a late leaf emergence or late leaf fall.[1]
Description
The Uttwiler Spätlauber is a cultivated apple (Malus domestica). It is also a cider and kitchen apple with main distribution in Thurgau (Switzerland). Expert opinions about its ancestry vary, some believe the Uttwiler Spätlauber is a chance seedling from Uttwil.[2]
Tree
The Uttwiler Spätlauber has few demands on soil and climate. The tree thrives best on moderately moist soil in a warm climate with dry, sunny summers. It is not uncommon for flowers to develop as early as the summer shoot.[3]
Fruit
The fruit is usually round, decreasing somewhat more towards the calyx. The skin is smooth, shiny, green, turning green-yellow only late. With a lot of sunshine fruits show a touch of brownish redness. The flesh is firm and crunchy, like Golden Delicious or Idared. It is also sour with a weak spice. It reaches its picking maturity in mid-October and can be stored for up to a year.[4] The skin then turns brown-black. It is considered to be an acidic all-purpose apple.[2]
Distribution
Uttwiler Spätlauber is a rare apple variety today. It is integrated into the National Action Plan for the Conservation of Plant Genetic Resources in Food and Agriculture (NAP-PGREL) of Switzerland.[4]
Usage in the cosmetics industry
The plant stem cell extract of the Uttwiler Spätlauber is used today in many cosmetic anti-wrinkle and anti-aging care products.[4]
