I purchased a solar powered ice cube maker that makes cubes in about 10 minutes. For when the power goes out and you need to keep food in the fridge.
Texas winemakers produce some really great wine, at a reasonable price. I admit to going more upscale, as in buying $25-$30 bottles, lol. But when I want a decent Riesling, I go to the liquor store and buy a bottle of Piesporter Spatlese, which runs between 9-12 bucks a bottle.
For cooking when power's out, I'll hook up my Traeger to the generator, too.
