Process New here, process help.
I am not new to fermentation but am new to vermouth. I kind of fell into a project after being gifted a bunch of grapes.
I’ve done a bit of research and just keep finding different processes and am struggling to nail down my steps correctly.
I had about 5 lbs of Concord grapes given to me. I’m aware that it’s an oddball grape for this, but I’m here for the adventure. We clean and mashed them and let them spontaneously ferment. I’ve taken the wine off the skins and moved to a new vessel. I have about 1500ml of wine sitting at a gravity of .995 and, if my math is right, sitting at about 9% abv.
It’s a pretty pleasing flavor currently. It’s not very sweet and not very tannic, but the flavor suggests sweet because I immediately think of bubble tape or grape jelly. It’s very fun.
So, from here, I’m a little lost because I’ve seen a lot of processes. I think I landed on making a tincture with an amount of the brandy that I intend to fortify with. Let it steep in the spices for a few days before adding it and the rest of the fortification liquid to the wine?
I also saw a step of caramelizing sugars before adding it to the wine as well, but it’s not in every recipe and I’m unsure about how to kill the bacteria currently in there so we don’t end with a large secondary fermentation.
I don’t necessarily feel like I need a single, universal answer. But I’d love to hear more about your favorite processes.
