La Braccesca vineyard in Tuscany
QUEEN OF THE
WINE CELLAR
Since the Middle Ages, vines for premium red wines have
been ripening on the slopes of the La Braccesca vineyard
under the blazing Italian sun, which was in ample supply
last summer. Today, the grapes mature under the watchful
eye of oenologist Fiamma Cecchieri, who always has
plenty to do at the winery.

with cleaning technology?
The Maultasche (Swabian dumpling) and Kärcher have one thing in
common: they both hail from Swabia and can be found all over the
world. Like Kärcher products, these delicacies wrapped in dough
are popular around the globe: from sambusas in Africa and wontons
in Asia to empanadas in South America. Join us for a brief journey
that shows how culinary delights can bring people together and
how cleaning technology can ensure carefree feasting.

repertoire. They are prepared as soup in a broth, with sautéed
onions or sliced with egg. The name is derived from the
Maulbronn monastery. Legend has it that the Maultasche orig-
inated there when resourceful monks tried to get around
the rules of Lent and “hid” the meat in spinach and dough.
