Switchel, the combination of apple cider vinegar, ginger, lemon and honey (or maple/agave syrup) is brilliant cold in summer and hot in winter. That would be something for Swiss cider producers!!!
Water with a splash ofhttps://www.kuehne.de/essig/essig-zitrone-essig-750ml is also extremely refreshing.
Neither of these products are available anywhere else in Switzerland....
