CELIA Dark is a dark lager, containing 100% Saaz hops, as well as Toffee Bavarian malt and sand-filtered water from the Žatec foothills. CELIA is traditionally batch brewed for over two months by Žatecky Pivovar, which is one of several microbreweries co-owned by the Carlsberg Group around the world. The brewery was established in 1801, and is housed in the castle walls of the city of Žatec. Brewed using a patented de-glutenisation process, CELIA has the benefit of being gluten-free, while a silicon filtration technique means the range is also suitable for vegans. In addition, a natural carbonation process is used to give the beers a light mouth feel, without compromising on taste.
