Heat the oil in a large Dutch oven over medium-high heat, add the kielbasa and brown. Remove the kielbasa to a paper towel-lined plate. Add the potatoes, paprika, coriander, allspice, carrots, celery, garlic, onions and some salt and pepper. Cook, partially covered, 5 to 6 minutes. Then wilt in the cabbage and season with a little nutmeg. Deglaze the pan with the beer. Add the stock and passata, then slide the kielbasa back in the pot and simmer to combine flavors, 15 minutes. Cool and store for a make-ahead meal. Reheat over medium heat. Finish the soup with the creme fraiche, herbs and lemon juice; serve in shallow bowls.
