Reducing the Sweetness in Muscadine Wine

[KonureKing]

Hello, I've got some decent experience with beer brewing but am pretty new with making wines. I've only made two previous batches, both of which were plums. So I'm a complete newbie with regular wines. My parents have a Muscadine vine that grows on their property. It produces a ton every year, so I'd like to use those. The only problem is I don't like sweet wines and from everything I read online, Muscadine wine is really sweet. What amendments could I add to the wine to make It dry and bitter? Would I just need to add additional tannins? I also thought about using Magnum hops to make it bitter. Please let me know what and how many amendments you would use to accomplish this for a 5-gallon batch. Any advice would be greatly appreciated.

Oak it and balance it by taste with acids doing a bench test is what I know helps ime. I'm not an expert.
