The Weingut Franz Keller cellars are an exclusive location near Baden, Germany. The modern structure consisting of cellars and vineyards surrounded by the wonderful landscape of the Black Forest. To make the complex perfectly in harmony with the surrounding environment, natural and sustainable materials such as glass, wood and stone have been used. Instead, as far as lighting is concerned, Platek products have proven to be particularly suitable as they are able to combine low energy consumption with an appealing aesthetic, which does not overpower nature. Menhir products, for example, thanks to the proposed variety of poles in three dimensions, guarantee a functional light able to make access routes safe for guests.
