* celantro wine is doable, your first question is what do you want to add with cilantro “aroma” to balance out “flavors”? You can get an approximation of a straight celantro aroma in alcohol by steeping a jar of chopped leaves with grain alcohol.
* A typical food has aroma compounds (your extract in alcohol) sweet/ sour/ bitter/ salt/ umami. Wines minimize umami, salt and bitter and focus on balancing sweet and sour. I could see a mix with an Asian theme of ginger garlic etc or Hispanic theme. As a first step at the lab bench I take the alcohol extract above and bench trial it with other flavors. The start for me is an acidic ingredient as lemon juice, rhurbarb, gooseberry, cranberry, tamarind, . . . wine is a acidic roughly pH 3.5/ alcoholic preservative system.
* when I try dandelion I have a backbone that provides sugar to ferment, nitrogen, minerals and vitamins for yeast growth, and tannic as an antioxidant. By itself cilantro has nothing to maintain yeast growth so you have to provide it.
A simple backbone is pear or white grape or even zucchini. A complicated backbone is pulling out the chemical bottles (ex EC Krause dandelion recipe) and producing a “sugar wine”.
There are lots of sugar wine recipes with names like elder flower wine, pine needle wine, beet wine, black berry tip wine, ginseng, dandelion wine, etc. They are good models on the type of ingredients that make a backbone and balance flavors.
A final wonder is pine needle had woodsy campfire notes, wonder how that would have been with celantro for aroma front notes?
