many thanks to responders
seems i have been demoted to "guest" and cannot log in but i would like to thank everyone for the help. i think i have a clear understanding as to what this is. i looked at the bottle again and im thinking that the cork is damaged as i can see that while the outer seal is in tack there are signs of seepage. as stated earlier i have no clue so i rely on the comunity for my education.
this experience was really interesting and i "raise a toast of the finest" to you all! im going to explain to my friend that the lack of care has rendered this bottle "near worthless" but should any one wish to pursue this please feel free to contact me and i will put you in touch with him directly.
once again thank you all,
