You can just use the principled shader and pull the transmission all the way up. The distortion should only be wrong if the bottle doesn't actually has a wall thickness or if the the IOR is wrong (~1.49 for glass)
Make sure to to turn the transmission bounces (and total amount) in the light path settings up - if the ray doesn't make it out of the glass that spot will remain dark.
It's also common to switch from the principled/glass shader to a transparent shader if the transmission depth is high enough (>4) using the light path node. This helps with performance and requires less bounces if you have a lot of glass in the scene
