Step 1

Cut fish into 4 portions.

Step 2

Whisk together wine, olive oil, garlic, pepper flakes, and hot sauce in a small bowl. Pour over salmon and seal bag closed, letting out excess air. Place in refrigerator for 1 hour, turning after 30 minutes. Remove salmon from the marinade, letting excess drip off, and place on a plate to stand at room temperature for 15 minutes. Discard any remaining marinade.

Step 3

Preheat an outdoor grill for medium heat and lightly oil the grate.

Step 4

Place salmon flesh-side down on the hot grill. Close the lid and grill for 3 minutes. Flip and grill an additional 3 to 4 more minutes. Sprinkle with salt before serving, if desired.
