The secret is in the blend of cane sugar and Maui natural white cane sugar.
Waialua has a mild burn level, and the subtle hint of vanilla in the after taste is a nice touch.
We recommend you chase Waialua with a glass of water. Though the sugars are what make this root beer taste good, they also leave a slight film on the top of your mouth, causing your tongue to stick to it slightly.
All in all this little jewel is worth the taste, and it's got a great bottle cap, ta boot. Hard to deny that winning combo.
