HELP! I need to make fake bourbon to not give away pregnancy!

Ok, common problem. I am a drinker, not in excess, but I drink socially and turning down a drink will be a dead giveaway when with my family or friends. I can't pull the diet card bc I want to eat everything in sight LOL. 
I LOVE bourbon and nobody else in my family does. I want to take an empty bottle and fill it with something that looks like bourbon so I can continue to fool everyone. I've read food coloring is really bad for you. 
All ideas are super appreciated. Bonus points for something that does not have to be refrigerated.
