Because its a drink without the downsides.
It's not overly sweet like a highball.
Or overly filling like beer.
Or overly aggressive like soju.
You can sip SWAY, gulp SWAY, shotgun SWAY, or just hold SWAY in your hand.
It's really the only drink that fits any occasion.
So as long as you're drinking, you should drink SWAY.
If you're not drinking, we're not sure how you got here.
