Make the dough: In stand mixer, mix the water, yeast, brown sugar, fine salt, 4 Tablespoons melted butter and 5 cups of the flour. Mix for about 30 seconds, letting all the ingredients get incorporated and the dough pulls together into one big mass. Lightly pat dough with your finger. If it feels wet and is sticking to your fingers, add a little more flour, 1/4 cup at a time. Dough should be soft but not sticky and should be pulling away from the sides of the bowl. Knead for 3-5 minutes in mixer. Cover and let rest about 30 minutes while oven is preheating.
Preheat oven to 425°F.
Cut dough into 12 equal pieces. If you have a food scale, weigh each one to make sure you come out with all equal sized pretzels.
Shape the pretzels: Roll each piece into about a 20 inch long rope. Working from the center and rolling outwards makes this job quick and easy. Bring the ends up, twist, fold over and press to get a pretzel shape. You could also just cut the rope into 2 inch pieces for pretzel bites.
Place the pretzels on a lined baking sheet. Silicone mats work best for this. Parchment can also be used, but be sure to spray it with nonstick spray.
Bring the baking soda bath to a low boil. Drop 1-2 pretzels in and boil for about 20 seconds. Remove and place back on baking sheet. If desired, sprinkle with pretzel salt. Repeat with the remaining pretzels.
Bake for 7-9 minutes.
After removing from oven, use the reserved 4 Tablespoons of melted butter and brush onto pretzels. This is optional, but will give you that authentic Wetzels Pretzels flavor!
Serve warm and pair with your favorite dipping sauce!
