Polonius3 1,000 | 12,446 4 Nov 2009 / #1The acidity of sauerkraut available in the US varies considerbaly. The highly popular Silver Floss brand is quite sour and needs tro be rinsed. Some of the Polish brands eg Krakus can be used straight from the jar after draining (without rinsing). Aniotehr popular brand in michigna is Vlasic sauerkraut. There are also many own brands of supermarket chains and different ways of packing it: jar, tin, plastic bag or straight from the barrel at some Old World style markets in big cities.Do you think some of the companies cheat by adding vinegar to their kraut which is much quicker than slowly brine-curing it?So which brand of sauerkraut do you prefer and why?
