hey im looking for a good simple beer recipe, ive just finished (and drunk) some nettle beer loosely based on a recipe from this website and am now looking to brew something without having to buy anything, so any beer with ingredients i can forage or get for cheap would be great also looking to use irish moss (carrageenan) as i bought some of this and my last lot didnt clear properly.
anyway yea any help would be appreciated,

Many thanks
