Manufactory Dyhrberg – Switzerland's First Salmon Smokehouse
Dyhrberg AG, headquartered in Klus/Balsthal (SO), is Switzerland's first salmon smokehouse and has been producing smoked fish specialities in the Nordic tradition since 1965. The range includes cold-, warm- and hot-smoked fish, including wood-oven salmon and smoked trout, gravlax (graved salmon), fresh salmon, halibut, deep-sea scallops and giant prawns (Black Tiger prawns), as well as frozen products under the KRISTA brand. Processing is carried out exclusively by hand without machines: the salmon is hand-filleted, dry-cured with sea salt and smoked in the wood oven over several days, up to almost a week. Selected salmon from the Pacific and Atlantic, organic salmon from Ireland and trout from Swiss organic farming are used. The manufactory supplies retail, gastronomy and end consumers via a factory shop, a retail shop in Berikon and the online shop lachsundmeer.ch.
