Heat the butter in a small saucepan over medium-high heat. Add the flour and cook, stirring until smooth, for 2 minutes. Slowly whisk in the beer so the mixture is smooth. Simmer until thickened, about 5 minutes. Add the Cheddar, Gouda, sour cream, mustard and paprika and whisk until the cheeses are melted, 2 to 3 minutes. Stir in the jalapenos, and season with salt and pepper. Serve with tortilla chips.
