This depends primarily on how much you want to brew and what style (batch vs continuous). The easiest first step would be to go with a glass gallon jug. If you want to go a little bigger, get a 2 gallon with a non metal spigot (plastic and stainless steel are ok). Spigots make it way easier to pour for 2F. Not sure it’s worth it for a 1 gallon jug but for sure for 2+ G.
