title_body: What type of beer should be used in making Beer Soup (Polewka Piwna)
upvoted_answer: A saison would be the closest if you want "authenticity". This soup was usually a breakfast dish made with very weak farmhouse style ale often served to farm workers. The beers were locally brewed often by the farmers themselves. It only had about 3-4% abv so even today's commercial saisons have a bit more (5-8% abv). Sometimes kvas was used. Kvas is a light brew made from fermenting stale/dried bread (1-3% abv).
