In the bowl of a stand mixer fitted with the hook attachment, add the water and sourdough starter. Mix well. The dough is very stiff.
Add the whole wheat flour, salt, and 12 g of honey. Close the stand mixer and let it mix for 5-6 minutes.
When the dough forms a ball and comes away from the sides of the bowl, cover the bowl with plastic wrap or a damp kitchen towel. Let it rise for 8-10 hours or until it doubles in size.
In the morning, lightly flour your surface and turn the dough onto the surface. Cut the dough into 8 pieces for larger bagels, 10 pieces for smaller bagels.
Shape the dough into small balls and let them rest on a parchment lined baking sheet for 10-15 minutes.
Push your finger through the dough ball and shape into a bagel. Let the dough rest for 30-40 minutes on the baking sheet.
Preheat the oven to 425 degrees F. Fill a Dutch oven ¾ of the way full with water and bring it to a simmer. Add 12 g of honey to the simmering water and let it dissolve.
Carefully add 2-3 bagels at a time to the boiling water. Let them boil for 30 seconds and remove the bagel. Continue until all the bagels are boiled.
Place the bagels back on the baking sheet. Bake for 25-30 minutes or until golden brown. Serve immediately.
