No. Merlot is a dry red that runs between 12%-14% alcohol. Port is a sweet wine that's about 20% alcohol.
You probably can, but keep in mind that port is much sweeter than red wine.
Yes and it will work well as both a pre-soak and a marinade.
I don't think so. Merlot is a good dinner or cheese party wine. Sherry is served in smaller quantities and is generally much stronger than Merlot. - And there is NO substitute for a good sherry.
The part of speech depends on the use of the word in context. If the use is "Port wine", the word is used to describe the noun "wine" and therefore is an adjective. If the word is used as a noun e.g., "...a glass of Port", it is a noun.
According to the book 'Substituting Ingredients - The A to Z Kitchen Reference' by Becky Sue Epstein, Fourth Edition 2010, Sourcebooks Inc. NAPIERVILLE IL. Page 135: You can use either Madeira, port or Marsala.
you can and cant
You can use equal parts dry sherry/pale sherry wine; not the cooking wine... the drinking wine. :)
Port.
Another strong wine such as Merlot Actually, Merlot is not a "strong" wine. Amerone gets its unique rich taste from the fact that grapes are allowed to sit outside on fresh straw for days to dry slightly. This accumulates their sugars before going to mash for wine. To substitute Amarone, say in Osso Bucco, you can use an inexpensive Marsalla cooking wine, then add one canned stewed prune for every 1/2 cup of wine you use. When finished, the prune will have disolved, but you will have added rich, sweet, dried fruit layer of flavor that Amarone is known for. Enjoy!
sherry
Sometimes.
I would say yes for most recipes.Use a richer full bodied red wine. If you are using the wine in a sweet dish (eg pears poached in wine) you may need to add something to make up fro the lower sugar in the the red wine, sugar or perhaps a spoonful of honey.
