A wholly different beast from the 10 year old and one of the rarest and most exclusive single-barrel bourbons ever produced, Michter's 20 Year Old Single Barrel Bourbon Whiskey has a seriously big flavor profile. With 10 percent more alcohol than its younger brother, this blend offers a fiery experience, with a luxurious balance of oak and spice, followed by a finish that swims with smooth cinnamon and caramel. A remarkably rare find, this cult blend is a genuine enigma but well worth tracking down if you love some sophisticated punch with your sip.

The younger brother of its 20 year old sibling, Old Rip Van Winkle Pappy Van Winkle's 15 Year Old Family Reserve Bourbon has become a legend in its own right. Bottled at 107 percent proof and hand-crafted according to the family's own secret recipe, only the very best and most heavily charred barrels are selected for this acclaimed blend. Laid to rest for 15 years, the whiskey emerges as a smooth, oaky liquid offering a unique silkiness on the palette. Simply sublime.

The eldest sibling in the range, Old Rip Van Winkle Pappy Van Winkle's 23 Year Old Family Reserve Bourbon is the rarest and most elusive of the Old Rip Van Winkle range - a remarkable 'wheated' bourbon enigma that very few have the opportunity to enjoy. Meticulously selected from the heart of the Rip Van Winkle Distillery warehouse, this oaky blend is unbelievably smooth, proving that every single month of its 23 years in the barrel has been worth it. Released yearly in the most minute batches imaginable, if you're lucky enough to get your hands on a bottle, we recommend taking it neat to enjoy the full uniqueness of its superb flavor.

Named after William Larue Weller, a legendary Kentucky whiskey maker, Weller bourbons are produced at the Buffalo Trace distillery in Frankfort, Kentucky. The William Larue release is part of the Buffalo Trace Antique Collection and is almost as hard to find as a rare Pappy. If you do happen to come across it, however, there's cause for celebration. On the nose, scents of pepper, oak, leather and caramel corn bring this spirit alive, whilst the rich palate entry with warming honey notes leads to an explosion of caramel, roasted almonds, figs and dates. At a remarkably high proof, this whiskey isn't for the faint hearted, but will reward those bold enough to sip neat.

A statement piece for any serious collection, the Double Eagle Very Rare 20 Year Old Bourbon from Eagle Rare is perhaps the most decadent and beautifully crafted bourbon whiskey in the world, both inside and outside the bottle. Beset with two crystal glass eagle sculptures, this handcrafted, custom decanter is eye-catching and elegant, and will certainly make a lasting impression upon any serious whiskey connoisseur. Aged for twice as long as the standard Eagle Rare iteration, the 20 Year old 'Very Rare' No. 3 has an upgraded 101 proof, making it an even complex and captivating high-end whiskey, which presents a fantastic balance of vanilla caramel and warm toasted oakiness, all the while oozing luxurious class and style.
