1. Put salmon steaks in a glass dish and pour in the wine, oil, and seasonings, turning salmon to coat well.
2. Cover with plastic and put in refrigerator for 2 hours or more, turning several times to make sure salmon marinades all over.
3. When ready, oil the grill grates (or fish basket if you have one) and set outdoor or inside grill to medium.
4. Remove fish from marinade, reserving marinade.
5. Put fish on direct heat on grill and cook for about 6 to 8 minutes, then flip and cook for about 6 to 8 minutes more, brushing several times with the leftover marinade.
6. Remove from grill to a platter and serve hot with wedges of lemon.
The salmon should be cooked all the way through and flake with a fork. Salmon is a solid, oily fish that can stand a little extra time on the grill without drying out.
One trick to know about grilling salmon is to let the fish 'tell' you when it's ready to flip. The fish will 'let go' of the grill when cooked properly and ready to flip, and then ready to remove. If the fish sticks to the grill, it's not ready to flip, so just be patient.
