Glockenapfel

"Glocken" means bell, which describes the characteristic shape of this elongated and tapered apple. ¶ 

My two Glockenapfels are medium-to-large, ribbed, tapered, and elongated. The photographed sample if anything understates this, but it has the better color (yellow) and blush. They are quite firm in hand. ¶ 

The lenticels are tiny, light in the blush and barely visible elsewhere, unless filled in with a bit of dark grey.

The other sample is taller and greener with a much smaller and fainter blush. It also has just a bit of russet near the stem.

On inspection, the green of number 2 is organized into lighter and darker stripes, a bit like the peel of an Ananas Reinette.

My assumption is that Glocken number two is less ripe. We'll see which is better for eating.

Eating

Both of these have firm, dense off-white flesh that is tart-forward and fine-grained but juicy.

The flavors are clearer in the riper (photographed) apple: cherries, berries (blackberries or raspberries) and spice. 

Both are satisfyingly crisp and crunchy.

This wikimedia image does a good job of showing Glockenapfel's elongated bell shape (photo: Sven Teschke CC BY-SA 3.0 DE).

Although I am enjoying Glockenapfel for eating out of hand, the acidity is a lot to take and I think might just be too much for modern tastes.

Other than that, it is a great flavor set, if you get one that is fully ripe. And I wonder about the Glockenapfel's qualities for cooking and cider.

Origins

Glockenapfel is a heritage apple dating from the seventeenth century in the north of middle Europe.

Trees of Antiquity calls it "the traditional variety used for strudel," and Wikipedia says it is widely grown in Germany (while noting it may have originated in Switzerland).
