The Maryensztadt brewery has been operating in Zwoleń since 2015 and is doing so well that they are just finishing building a second brewery in Sycyna. From the beginning, they have offered a wide range of styles, from classic to new wave IPA, aged and freeze-distilled beers.

So far, the Maryensztadt brewery has created 24 different Baltic Porters. The offer starts with a porter from the Klasycznie series, 22 Plato, 8.7% alc. Then there is the most famous and awarded (bronze at the European Beer Star) Imperial Baltic Porter (26 Plato, 10.1% alc) Gwiazda Północy with the addition of smoked plums and dried figs. Maryensztadt was the first to create a Baltic Porter with a Plato close to 30, with the Projekt 30#1 beer (29.33 Plato, 10.5% alc.).

They are currently developing a series of porters freeze-distilled and aged in oak barrels in the Project Barrel Aged series. They also do not shy away from crazy experiments such as Darkness My Friend Imperial Baltic Porter with Smoked Mackerel (10.1% alc.).
