Survival foods! Beside Potatos, turnips, carrots, and Rutabagas are good choices and all store well for a long time. In season, turnips are just about the fastest growing vegetable. You can eat them, your animals can eat them. (So can wild animals...Other readers....fencing is probably the first thing a starting gardener should buy! Ellendra...I know you already know this!)

I actually do all my brewing with ordinary bread yeast. I know there are lots of specialized strains, there’s even a shop nearby that sells them. But when I decided to try my hand at winemaking I chose to look for the simplest method possible. Results have been good. I just don’t drink that much, so I stopped making it. It’s a good skill to have.
