The Travelling Merchant sells items to fill your Vampire Hunter's Kit (1 per slot) and
wychwood to restore sun weapons.
There is a bottle of Champagne du le Stomp spawned at four locations. It is a simple quest. When found you just take it to Arik Lorensk the bar tender, a man of few words. The side quest counts as 10% of your Barovian Daily. Also he pays 10 coins, 3 omens, 1,107 copper, and 2,540 XP.
Note: The merchant found near the ruins enters the scene near the river edge and walks about half way up the cliff side.
Happy Hunting!

I updated the map at the top, found 2 spawns for the red wine. The witches cart at the base of the hill near campfire in the Cursed Meadow. The brick wall in the ruins, where the Restless Dead encounter takes place. That is a total of 6 bottles. When Sybella has her 5 quests in Ravenloft these bottles count as missions. All you need to do is find the bottle spawned and turn it in at the bar. I am thinking there might be 2 more bottles, as the map seems unbalanced.
