This is great whiskey. It's not "the best", but it's such a great value for the price, it's pretty much the first whiskey I mention to anyone who is looking for some sort of portal into the world of great whiskey.
Wait, what? Is french pressing your beer actually a thing?
I use a french press a lot, mainly for coffee, sometimes tea - but I've also used it to emulsify salad dressings and stuff - but that seems like a funky thing to do.
In the time it would take to infuse an oil, or a liquor, your beer would go flat.
It's not going to filter out ALL of the sediment from the pie, or whatever, so you are going to have a backwash of sorts. There's always some leftover sludge whenever I make coffee (but I like to drink the sludge. It's like Turkish coffee.)
I don't think you are going to get the effect you are looking for. You are essentially "dry hopping" your beer, but not giving it enough time for the flavor to infuse in a realistic way. I would imagine the best way to transfer flavors like that would be during fermentation, or right after fermentation, prior to filtration and carbonation.
