Heat the olive oil in a large pot over medium heat.
Add the chicken, diced onion, and crushed garlic cloves.
Cook for about 5 minutes, until the chicken is lightly browned and the onion begins to soften.
Pour in the water, white wine, and lemon juice.
Stir in the sliced ginger, sugar, bouillon cubes, bay leaves, and peppercorns.
Bring the soup to a gentle simmer, then lower the heat to medium-low.
Let it cook for about 45 minutes.
Remove the crushed garlic cloves and discard them.
Transfer the chicken to a cutting board and chop it into bite-size pieces.
Add the carrots, celery, kohlrabi, rosemary, and thyme to the pot.
Reduce the heat to low and cook for about 20 minutes, until the vegetables start to soften.
Bring the soup back to a boil.
Return the chopped chicken to the pot along with the egg noodles, minced garlic, and grated ginger.
Remove the pot from the heat and let it sit for about 10 minutes, until the noodles are tender.
Season with salt to taste and garnish with chopped parsley before serving.
