Sometimes it can be tough for those following a ketogenic lifestyle to indulge in their love of cocktails. Many drinks are loaded with sugar and carbs, which can easily kick them out of ketosis. However, this doesn’t mean that you have to sacrifice your favorite bourbon-based drinks just because you’re watching your carb intake. In fact, bourbon is a relatively good choice for keto drinkers since it’s made from corn, which has lower carb content compared to other grains.

But not all cocktails are created equal, and some traditional recipes can be problematic. Take the Old Fashioned or Whiskey Sour, for example – these classic drinks often contain added sugar or sweeteners that can quickly add up in carbs. So what’s a keto bourbon lover to do? The answer is simple: get creative with your ingredients! By experimenting with new combinations and substituting some key ingredients, you can create delicious and keto-friendly cocktails that won’t blow your diet.

In this post, I’ll be sharing some of my favorite low-carb bourbon cocktail recipes, from spicy and savory to sweet and refreshing. Whether you’re a seasoned mixologist or just starting out, these recipes are sure to satisfy your cravings without compromising your dietary goals. So sit back, grab your favorite bourbon, and get ready to discover the best keto-friendly bourbon cocktails out there!
