So a while back I was having a conversation with my grandmother who who lives in Portgual, and beer came up in the conversation. She told me that when she was younger she used to home brew in Portugal. However, she said that Lupini/lupin beans were used in the recipe, along with some type of grain, (she couldn't remember what type of grain). And lupini beans were quite popular to use in beer in Portugal. Im really curious to know how lupini beans were incorporated in this but she is very elderly and does not remember how she made it. I would like to replicate this beer that my ancestors drank but I cannot find anything like it on the web...........Does anyone have any idea on how the lupini beans could of been used? Mashed? Thrown in the boil? Thrown in the fermenter?
