Jameson 18 year Old Limited Reserve is the Master Blender's hand-picked selection of very old Jameson Irish Whiskey, aged in oak casks for at least 18 years.First introduced in 2002, Jameson 18 Year Old Limited Reserve is very limited in stocks and consequently is sold internationally on strick allocation to markets.Rich, complex and truly rare - only limited stocks of this whiskey are available. Thus, each bottle is individually numbered. The superlative Jameson 18yo has long been considered one of the brightest stars of the range. This blend of two potstill whiskies and a single grain is matured in Oloroso sherry casks and finished in bourbon wood for 6 months for a brilliantly complex potstill character.
