Not super hot but delicious. Definitely try it if you're in the Twin Cities and see it at the farmers' market. If it really sounds like your thing it looks like you can order it online.
On the larger version of that image you can easily read the ingredients, its very simple:
Gochujang, rice vinegar, sesame oil, water, brown sugar, honey, cayenne. Sweet, tangy, hot, rich.
