This “gushing” when you open the bottle is never a good sign. It means overcatbonation and it’s usually caused by contamination. Of course the chance of contaminating a beer batch is way bigger when you use some alternative microorganisms to ferment the sugars (apart from beer yeast). I’ve never tried this beer, but think that it should not behave this way.
Of course this is not always bad. Contaminating a baths with bacteria is sometimes desired result!
I like a lot the triple exposure from the first photo and its “ghost” effect.
Cheers!
Geez, at first I thought that there might be someting wrong with the beer, but then I decided that it must be the Kvass that is causing the "gushing". You can give it a try next time you find yourself in Nosferatu :)
Glad that you liked the photos Miro and thanks for stopping by! :)
Cheers!
