My best guesses are CGF 1988 . The 88 on the base of the bottle is reliable for these older bottlings . WT 12 20002005 . You cannot date the more recent WT exports by the number on the bottle and the laser codes from this era are similarly inscrutable . This style of label was used 20002011 , so it must be between those dates . Given the separate crimson strip on the bottom , this looks like a transition label between the splitlabel and the later single label bottlngs . Therefore , I would guess it was from the earlier half of the 2000 s . WT 8 USA 1986 . The 86 on the base of the bottle is reliable for these older bottlings . WT 8 JPN 1996 . The laser code is more reliable than using the number on the bottom of the bottle . Further proof that this bottle is from after 1992 , is that it has the phrase 8 yearsold embossed on the neck .
