Thee story of rum is complex, as complex as the blending process involved in producing the best brands in the world''s greatest spirit. It involves a cast of thousands to tell anywhere near accurately. It includes some of the greatest heroes and villains of history: colonialism, pirates, wars, slavery, and the growth of global capitalism. A ten part, big budget, television series or a blockbuster Hollywood film would struggle to do the story justice. Key points, oddities and anomalies, would be glossed over, ignored or conveniently forgotten. In short, it is an intricate, multifaceted story, by turns fascinating and absorbing and at times downright alarming. This book tells only part of A Rum Tale . The origins of rum are difficult to trace other than there is one indisputable fact - wherever in the world sugarcane is grown, rum (or something related to rum) is and has been produced.

The ''cast of thousands'' I mentioned above include such historical luminaries as Christopher Columbus, George Washington, Admiral Lord Nelson, John Adams, Captain William Bligh, Earnest Hemmingway and, in contrast by his abstinence and brilliant exhortations that rum was ''a slave owners drink'' Malcolm X: A whole host of major and minor characters throughout history that no doubt would have made for a great dinner party, with or without rum being served. And yet rum remains, at least until recently, considered a ''childish'' drink, something that neophyte girls order on a first date when their priapic beau takes them to a cocktail bar: "oh, I''ll just have a Bacardi and coke please." Possibly one of the most revolting drinks in the history of trying to have something resembling fun. Rum however, is on the march. New small batch distilleries are springing up all over the world, new markets opening and ''rum festivals'' becoming commonplace across the world. This both dark and light drink, seeped in history, is finally starting to find its place. I have to admit that this is probably because the sudden interest in gin from the mid 2000s has started to wane through saturation, so the thirst for the ''next big thing'' has centred on rum. I like to think of rum as a sleeping giant in that context, unencumbered by market forces, a drink for those ''in the know'', which brings me neatly on to the matter of tasting and evaluating rum.

Unlike other spirits, rum has no international classification- basically anything goes. There are some fantastic and very learned ''rum scholars'' writing books and blogs, of whom I am greatly indebted to researching and writing this book- nonetheless I take issue with pretentious and meaningless tasting notes and refer you to David Hume (1711-1776); my book is for rum enthusiasts- people interested in the history of drinks they enjoy, not for elitist snobs. I hope it is a beginners guide, so to speak, and doesn''t smack of any snobbery or petty prejudice. David Hume, the Scottish philosopher and historian attempted to analyse the problem of how to define good from bad in matters of judgement and expertise in his essay ''Of the Standard of Taste'' (1757). Hume was concerned with critical judgements and how (or why) one pronouncement can hold sway over another contrary point of view. One of the major concerns clouding critical judgements- claiming one rum the best in its class, over another, boiled down to an inability to distinguish between simple facts and expressions of sentiment and/or emotion. For example, an ardent supporter of a certain football team may witness a goal scored by their team that exhibits skill, balance and athleticism and pronounce it a ''beautiful goal''. If the opposition, moments later, score a goal of comparable merit, it is unlikely to be viewed with dispassionate reason.

This is because the initial judgement is coloured by sentiment and emotion and therefore subjected to prejudice. Critical verdicts based upon sentiment and emotion are devoid of any discernible truth-value and thus rendered, in Hume''s words: "absurd and ridiculous". For Hume, standards of taste and their accompanying critical judgements are often determind by slight differences, nuances and subtle oppositions. As a general rule people respond to more obviously apparent aspects and qualities in ''things''. How many times have you heard people express pleasure at the sight of a sunset , yet the sunsets every dusk all over the world so why should one sunset be any more beautiful than another. This point, in turn, opens up questions about perception, time and place, or, if you like, ''being in the moment''. Some years ago I visited filmmaker/ wine producer Francis Ford Coppola''s winery in Geyserville, California. A stunning estate that contains a small museum of Coppola film artefacts and props.

My wife and I toured the estate and had a private tasting of the over 40 wines they produce onsite (I hasten to add we didn''t taste all 40 wines but a selection of their vintages). If I am truly dispassionate in my assessment of the wines we sampled, they weren''t actually that great, but there was something about sitting behind Don Corleone''s (Marlon Brando''s) desk from The Godfather sipping a fair to middling Pinot Noir that was very seductive on my judgement. I subsequently purchased a case of mixed wines to ship back home but when opened and drunk back in the UK on a cold, wet November evening, they proved to be a profound disappointment. Situation, moment, sentiment, blimey, even the bloody weather can cloud judgements. Hume makes this point about the ''fine margins of taste'' and illustrates it with reference to Miguel de Cervantes (1547-1616) timeless novel Don Quixote (1605). In one scene in Cervantes episodic master work, Sancho Panza tells a story about two wine connoisseurs tasting and evaluating a barrel of wine which they have been told is the finest produced in the whole of Spain. The first of the ''experts'' samples the wine with the tip of his tongue, rolls it around his mouth and spits it out into a bucket and concurs that the wine is indeed of good quality and has a finish of rusty iron. The second ''expert'' smells the wine, breathing deeply and agrees that it is of very high vintage but that has a hint of burnt leather in its bouquet.

Some onlookers ridicule and dismiss the judgements of the so-called ''experts'' accusing them of making false and bogus judgements. However, when the all of the wine has been drunk a rusting iron key and a burnt leather strap are found in the bottom of the empty barrel. Hume deploys Cervantes'' tale to illustrate his view that developing good taste is a matter of refinement that requires time and needs to be practised in as detached a manner as possible. For Hume, it is not a matter of determining if one stated position in contrast with another is true or false, or vice versa; but in deciding which is simply better according to certain principles. In summary, Hume sets out the following criteria for sound taste and judgement: "strong sense, united to delicate sentiment, improved by practice, perfected by comparison, and cleared of all prejudice, can alone entitle critics to this valuable character of sound judgement and taste". In other words, practice and perseverance, variation, considered comparison - find what you like and then measure according to that standard - and never stop looking for something new makes a rum connoisseur, not daft tasting notes about coconut husks and rotting mangoes. I can''t actually remember when I first tasted rum and thus, if I actually liked it immediately. It is possible, even likely, that my first contact with the ''flavours'' of rum wasn''t through drinking at all, but through cakes and ice cream, sweet treats.

This stands in stark comparison to other spirits. Experimenting with alcohol at teenage parties inevitably is a matter of trial and error, with more errors occurring to the novice drinker. I can remember being violently ill on gin, an experience that has coloured my ability to drink ''mother''s ruin'' to this day. Whiskey too presented its pitfalls, particularly during my undergraduate years and vodka only seemed to serve one notable purpose - to get drunk as quickly as possible (a position I later revised when I lived in Russia - although getting drunk in Russia is less of a vice than a necessity and national pastime). I don''t think I ever considered rum to be a childish drink as was a common misconception in some quarters, quite the opposite in fact. If I am to identify two people to thank for my love of rum it is my father and his long-time friend Joseph Christopher (whom I am named after). My father met Joseph ''Joe'' Christopher at Durham University in the early 1960''s where they were both Post-Graduate researchers in the physics department. Joe Christopher was born and bred on the island of Bermuda which has a rum related history and culture thanks in the main to the Gosling Brothers (see Rums of Distinction: Goslings Black Seal).

My father didn''t drink alcohol regularly (having come unstuck at a student party on Scotch) aside from the odd sociable pint of bitter in the Student''s Union-or wine at special occasions. Joe Christopher introduced him to the wonders of rum, sales of whi.
