how can I achive this kind of material for glass? (photo attached). It looks like noise texture on very high scale, but when I try to set it, the bottle roughness is rising so high it losts the shiny glass material character. Thanks for your advice.
I would use something like this for the material - use the Noise texture as the basis for a Bump Node, and then use that as the Normal for the glass. I mixed it very heavily with white first (.998) otherwise, it looks too strong and unrealistic. You can also do this by adjusting the strength on the bump node, but I feel this gives more "fine" control. Lastly, use the Facing output of a Layer Weight node, to mix the inner "lighter color" with a more opaque outer "brownish". Don't forget to adjust the Blend Mode settings if you are using EEVEE (right side):
