“South Africa meets Ascona”

“South Africa meets Ascona”


On April 9 2020, Bernard Hess and his Winery Mimosa from South Africa will be hosts for the second time at the Romantik Hotel Castello Seeschloss. Chef Alessandro Longhi will prepare together with Bernhard Hess a menu on the topic of “Ticino meets South Africa” and will serve the wines of the Mimosa-Lodge.
Montagu is a city in the district of Langeberg, Cape Winelands, Western Cape Province in South Africa. It is located in a fertile valley at the confluence of the Kingna River and Keisie rivers on Route 62 just 2 hours from Cape Town. The Mimosa Lodge is not a wine farm in the “usual” sense. Rather, Mimosa is a place to stay and be pampered by the Hess family on the well-kept estate. Not only in one of the pretty cottages, but also with a fine dinner in the restaurant and a glass of homemade Cabernet Sauvignon from the Robertson area. The enologist Bernhard Hess is also a passionate chef. What could be more appropriate than exploring the wine theme in more detail? The wines, as well as the gourmet menu creations will meet the highest quality expectations.


Let yourself be pampered and book your table today …..
