Browar Mazurski has been operating in Ełk since 2016. When looking for a location for the brewery, they chose a region with rich brewing traditions – Masuria. They focus on selling around the chimney and classic styles, sometimes with a touch of fantasy, such as Farmhouse with pine shoots. They are distinguished by the fact that all their beers are saturated with nitrogen, not carbon dioxide. It is also interesting that they are the only ones in Poland who regularly brew Red Ale style beer.

Mazurski Porter brewed since 2018 is a classic with a twist, 20 Plato and 9% alc, with the addition of oat flakes and cocoa beans. It is one of the few Baltic Porters saturated with nitrogen, which allows it to build a unique texture and foam. It won the brewery two medals at international competitions: gold at The European Beer Challenge in 2021 and silver at the Lyon International Competition in 2024.
