I would like to add a lemon finish to my Belgian Whit and I have read a lemon tincture is a good way to do this. I have no idea what this is or how to do it. I just brewed yesterday and am fermenting now. How do I make a lemon tincture and when do I add it? I have read a bit that vodka is somehow used and I add it when I transfer to the secondary? Please help. Thanks!
