In heavy saucepan, bring chicken broth to a boil. Add wild rice and stir. Cover pan and reduce heat to low. Let simmer for one hour, until rice is tender and has popped open.
Meanwhile, cook bacon in a frying pan over medium until almost crisp, about 8-10 minutes.
Add butter to bacon pan, add onions, celery, mushrooms, garlic, thyme and salt and pepper. Cook over medium heat for 5-7 minutes, until onions are translucent. Remove from heat and fold in parsley, hazelnuts and grapes.
Add rice with any remaining liquid in pan, to vegetable mixture and toss well to combine.
