Most Commonly Used Name: Kastanie (German for Chestnut, it’s pronounced Kuh-stawn-yuh)
Mode of Genetic Inheritance: Recessive
Morph Type: Single Recessive Mutation
First discovered by a German Corn Snake breeder, Frank Schaub, the Kastanie is a color mutation. We have been breeding them for many years, but they were called Rosy Bloodreds. The Rosy reason for that name turned out to be the Kastanie mutation causing the color namesake of the Rosy Bloodreds. Ours originated from a collector who found a pair of Rosy Rats in the upper keys of Florida. He bred them together and got nothing but more Rosy Rats (Key Corns), but when he bred two of those together, 1/4 of the brood was what we now call Kastanies.
The U.S. line of Kastanies from Frank’s German lineage are generally less-brightly colored, but have beautiful deep and rich dark reds and the head and neck of the German Kastanies are much redder than the U.S. line. The U.S. line has more overall orange body coloration. Both are stunning.
Like most corn snkaes, Kastanie hatchlings begin very differently than they will look at maturity. This picture shows two U.S. Kastanie hatchlings and one German-Line Kastanie hatchling (head on far-right). 
Important Note:
These images are not renderings of the actual animals being offered, (except for uniquely offered snakes found in the SURPLUS section of this web site). We do not provide pictures of individual hatchling snakes for sale, nor do we recommend that you ever choose a new pet based on an image of its neonatal form. Corns change so dramatically from hatchling to adult, they will NEVER have the same colors or contrasts throughout maturity. While most of the snakes we produce will mature to resemble the featured adult image(s) on our web site, unlike manufactured products that are respectively clones of each other, the nature of polygenic variation results in each animal being similar but not identical to others of its morph. The snake we select for you may not mature to be identical to the pictured examples, but will be chosen based on our experience of observing which neonates will mature to properly represent their respective morph. We take this responsibility very seriously, and therefore publish the guarantee that we will exchange your SMR snake if it does not mature to be like our advertised examples.
