Heat a large pot over medium heat and add the pancetta. Cook until the pancetta is crispy and the fat has been rendered. Remove the pancetta with a slotted spoon and place it on a paper towel to drain any excess grease. If using bacon then cook to desired doneness.
Add the 1 tablespoon of butter or olive oil to the pot and keep it over medium heat. Add in the garlic and pepper flakes with a pinch of salt and pepper. Cook, stirring often, until the garlic is fragrant and slightly golden, about 2 to 3 minutes. Pour in the red wine and bring it to a boil, reduce heat and simmer, stirring occasionally, until the wine reduces by 1/3.
While the red wine is boiling, bring a pot of salted water to a boil and cook the pasta. Cook it until it’s very al dente. Then drain pasta
Add pasta, pinot noir sauce, 4 tablespoons butter/olive oil, and pancetta and mix together. Add more wine to mix if desired. Pasta will soak up the red wine.
Serve the pa! sta and top with the parmesan and herbs.
