It’s basically a secret weapon when it comes to dog care. If your dog has eaten something hard to digest (like a toy or a bone), feed them a serving of sauerkraut, and most dogs will need to go outside 10 minutes later and everything will come out.

I'm quite sensitive to it and can only have a spoonful or so and generally plan to work from home the next day. Note that the store bought stuff is often heated or similar and doesn't contain anywhere near the same level of bacteria.

Putting sauerkraut into barrel was a ritual for whole family - cutting cabbage heads on manual spinning cutter, then smaller person in the household would but a plastic bag on one foot/both feet and stand in the barrel, while family was adding more layers (to compress it all and get juices from cabbage out and salt in). It was mixed with some apples, spices like whole black pepper and salt. Once closed and water was put in, over time it would start regularly 'farting' out excess gasses from fermentation.

Lasted whole winter and then some, base for many nice meals but by far the best is hearty cabbage soup, tradition for not only Christmas dinner. That sauerkraut tasted/tastes much better than best bio stuff I can buy in most expensive Swiss/German shops.
