The best way, I think, is to create a store and sell your own producs - write an ebook, sell merch, whatever fits best.
You could also try patreon.
Can you send me a link to your blog? Maybe I will have more ideas.
And I would create a store, contact whiskey manufactures, and start selling their products, that shouldn't be too hard.
In fact, even for affiliates - contact the companies you want to advertise for personally, and offer them ads. Create beautiful banners that fit your design really well, and place them instead of adsense. And write articles along the lines of "the top best whiskey brands", with affiliate links. It will be much more profitable that way.
