Oh yes there are.
Sinebrychof and
Olvi are the biggest brewerys here. Products like
Karhu, Koff & Lapin Kulta for some to mention. They are the oldest and common here. Some new, minor companies like Laitila make very interesting beers which have a rich flavour (Keisari and Marsalkka) and nowadays I rather spend my money on them although the price is somewhat high. Pubs do import Czech, German and British brew too and have a wide availability.
Finns have always drank a lot. Some would say too much. In history, until 1940's people made a booze called sahti and kilju that had a strong odour and tasted somewhat terrible. Long time ago, at a time of First World War and after that there was a twenty years period when alcohol was controlled and prohibited by law. Many made sahti secretly at home. Prohibition brought a taboo stamp for long time for being drunk in public or if you even went to a pub. But things changed of course. I'm soon an old fart and have not seen those days, but my generation's parents remember it still.
Punk rockers have always made kilju at home. Once when the Scots Oi polloi were touring in Finland first time they were amazed by kilju here and there's a rumour that when they returned to Britain and met the Doom guys there (who were going to tour next Finland), they told that "beware those Finns, they will give you a drink called 'kill-you' and they'll take you to hot sauna and spank you with tree branches!"
The branches are actually made of birch and used to stimulate the skin while it's 85 celsius hot in sauna. It's a very old tradition.
