In a large mixing bowl, whisk together the active sourdough starter, warm water, and 10g olive oil until well combined.
Add the bread flour, fine sea salt, and optional sugar to the wet mixture, then mix with a spatula or your hands until no dry spots remain and a shaggy dough forms. Cover the bowl with a damp cloth or plastic wrap and let it rest for 30 minutes (autolyse).
Over the next 2-3 hours, perform 3-4 sets of stretch and folds every 30-45 minutes. To do this, lightly wet your hands, grab a portion of the dough, stretch it upwards, and fold it over itself towards the center of the bowl, rotating the bowl each time.
After the stretch and folds, cover the bowl and let the dough bulk ferment at room temperature (around 72-76°F / 22-24°C) for 8-12 hours, or until it has visibly doubled in size and appears bubbly.
Generously drizzle 3-4 tablespoons of olive oil into a 9x13 inch baking pan, ensuring the entire bottom and sides are coated.
Gently scrape the fermented dough into the oiled baking pan. Drizzle a little more olive oil over the top of the dough. Cover loosely with plastic wrap and let it rest for 30-60 minutes at room temperature, allowing it to relax and spread.
Using oiled fingertips, gently press deep dimples all over the surface of the dough, pushing down until you feel the bottom of the pan.
Sprinkle generously with flaky sea salt and arrange your desired toppings, such as fresh rosemary, halved cherry tomatoes, or thinly sliced garlic.
While the dough rests, preheat your oven to 425°F (220°C) with a rack in the middle.
Bake the focaccia for 25-30 minutes, or until it's golden brown and cooked through.
Carefully remove the focaccia from the oven and immediately transfer it to a wire rack to cool slightly. Drizzle with a little more extra virgin olive oil before slicing and serving warm.
