I think that poke or polk berries may have been mixed in with the elderberries that I use to make some wine. i hear the polk berries are poisonous. I have heard just the seed is and that they should be boiled first, so Im not sure. The berries were rinsed in hot water, drained and placed into a cheese bag in the fermenting bucket and boiled sugar water was poured over them. Does anyone know if this wine needs to be tossed out because of the polk berries, or if it will be okay to drink. Help.
