The Whiskey Machine: Nanofactory-Based Replication of Fine Spirits and Other Alcohol-Based Beverages The Whiskey Machine: Nanofactory-Based Replication of Fine Spirits and Other Alcohol-Based Beverages © 2016 Robert A. Freitas Jr. All Rights Reserved. Abstract. Specialized nanofactories will be able to manufacture specific products or classes of products very efficiently and inexpensively. This paper is the first serious scaling study of a nanofactory designed for the manufacture of a specific food product, in this case high-value-per- liter alcoholic beverages. The analysis indicates that a 6-kg desktop appliance called the Fine Spirits Synthesizer, aka. the “Whiskey Machine,” consuming 300 W of power for all atomically precise mechanosynthesis operations, along with a commercially available 59-kg 900 W cryogenic refrigerator, could produce one 750 ml bottle per hour of any fine spirit beverage for which the molecular recipe is precisely known at a manufacturing cost of about $0.36 per bottle, assuming no reduction in the current $0.07/kWh cost for industrial electricity. The appliance’s carbon footprint is a minuscule 0.3 gm CO2 emitted per bottle, more than 1000 times smaller than the 460 gm CO2 per bottle carbon footprint of conventional distillery operations today. The same desktop appliance can intake a tiny physical sample of any fine spirit beverage and produce a complete molecular recipe for that product in ~17 minutes of run time, consuming <25 W of power, at negligible additional cost.

Introduction Specialized nanofactories will be able to manufacture specific products or classes of products very efficiently and inexpensively. This paper is the first serious scaling study of a nanofactory designed for the manufacture of a specific food product, in this case high-value-per-liter alcoholic beverages. The main purpose of this paper is to assess the technical opportunities for the inexpensive chemical analysis and manufacturing of fine spirits and other alcohol-based beverages using the equipment and techniques of atomically precise manufacturing. Of particular practical concern to commercial interests is the vulnerability of existing fine spirits business models to potentially disruptive new sources of atomically indistinguishable replicant products having significantly lower production cost and/or higher consumer desirability than traditionally produced products. The discussion here focuses on alcohol-based fine spirits, using whiskey1 as the exemplar beverage product. Other closely related product classes, including distilled spirits such as cognac, rum, brandy, gin, tequila, vodka, Japanese shochu, and Chinese baijiu, other beverages of intermediate alcohol content such as Japanese sake and liqueurs2 such as Bénédictine, Chartreuse, Grand Marnier, nalewkas, and American schnapps, and fermented and fortified beverages of low alcohol content such as champagne, beer, wine, sherry, and cider, technically could be synthesized by similar methods if product pricing and manufacturing costs permit, as could perfumes and fragrances which are often solvated in fine spirits such as brandy and cognac,3 but these applications are not discussed extensively in this document. Non-alcoholic beverages – such as coffee, tea, milk,4 juices, and carbonated sodas – could in principle be manufactured in the same manner but might not be justifiable purely economically unless the cost of energy drops a bit; these also are not discussed further in this document. While further investigation will be required, the analysis presented here makes a compelling case that the following capabilities may be enabled by the development of nanofactories and atomically precise manufacturing: (1) Quickly and inexpensively performing a quantitative assay of all organoleptic congeners

  • Whisky Bible
    WHISKY BIBLE FOURTH EDITION aqua vitae uisge beatha – ‘water of life’ A brief history of Whisky The Gaelic ‘usquebaugh’, meaning ‘Water of Life’, phonetically became ‘usky’ and then ‘whisky’ in English. Scotland has internationally protected the term ‘Scotch’. For a whisky to be labelled Scotch it has to be produced in Scotland. ‘Eight bolls of malt to Friar John Cor wherewith to make aqua vitae’. The entry above appeared in the Exchequer Rolls as long ago as 1494 and appears to be the earliest documented record of distilling in Scotland. This was sufficient to produce almost 1500 bottles. Legend would have it that St Patrick introduced distilling to Ireland in the fifth century AD and that the secrets travelled with the Dalriadic Scots when they arrived in Kintyre around AD500. The spirit was universally termed aqua vitae (‘water of life’) and was commonly made in monasteries, and chiefly used for medicinal purposes, being prescribed for the preservation of health, the prolongation of life, and for the relief of colic, palsy and even smallpox. Scotland’s great Renaissance king, James IV (1488-1513) was fond of ‘ardent spirits’. When the king visited Dundee in 1506, the treasury accounts record a payment to the local barber for a supply of aqua vitae for the king’s pleasure. The reference to the barber is not surprising. In 1505, the Guild of Surgeon Barbers in Edinburgh was granted a monopoly over the manufacture of aqua vitae – a fact that reflects the spirits perceived medicinal properties as well as the medicinal talents of the barbers.

  • The Perceptual Categorisation of Blended and Single Malt Scotch Whiskies Barry C
    Smith et al. Flavour (2017) 6:5 DOI 10.1186/s13411-017-0056-x RESEARCH Open Access The perceptual categorisation of blended and single malt Scotch whiskies Barry C. Smith1*, Carole Sester2, Jordi Ballester3 and Ophelia Deroy1 Abstract Background: Although most Scotch whisky is blended from different casks, a firm distinction exists in the minds of consumers and in the marketing of Scotch between single malts and blended whiskies. Consumers are offered cultural, geographical and production reasons to treat Scotch whiskies as falling into the categories of blends and single malts. There are differences in the composition, method of distillation and origin of the two kinds of bottled spirits. But does this category distinction correspond to a perceptual difference detectable by whisky drinkers? Do experts and novices show differences in their perceptual sensitivities to the distinction between blends and single malts? To test the sensory basis of this distinction, we conducted a series of blind tasting experiments in three countries with different levels of familiarity with the blends versus single malts distinction (the UK, the USA and France). In each country, expert and novice participants had to perform a free sorting task on nine whiskies (four blends, four single malts, one single grain, plus one repeat) first by olfaction, then by tasting. Results: Overall, no reliable perceptual distinction was revealed in the tasting condition between blends and single malts by experts or novices when asked to group whiskies according to their similarities and differences. There was nonetheless a clear effect of expertise, with experts showing a more reliable classification of the repeat sample.

  • Brewing Grains What Is Malt?
    612.724.4514 [email protected] www.aperfectpint.net Brewing Grains Brewing grains are the heart and soul of beer. Next to water they make up the bulk of brewing ingredients. Brewing grains provide the sugars that yeast ferment. They are the primary source of beer color and a major contributor to beer flavor, aroma, and body. Proteins in the grains give structure to beer foam and minerals deliver many of the nutrients essential to yeast growth. By far the most common brewing grain is malted barley or barley malt, but a variety of other grains, both malted and unmalted, are also used including wheat, corn, rice, rye, and oats. What is Malt? To put it plainly, malt is cereal grain that has undergone the malting process. In the simplest terms, malting is the controlled germination and kilning of grain. Malting develops the diastatic enzymes that accomplish the conversion of starch to sugar during brewing and begins a limited process of conversion that makes the starches more accessible to the brewer. Malting also gives brewing grains their distinctive colors and flavors. Only the highest quality grain, called brewing grade, is selected for malting. Brewing grade grain is selected for, among other things, high starch content, uniform kernel size, low nitrogen content, and high diastatic power. Diastatic power is the ability of grains to break down complex starch molecules into simpler sugars for brewing. It is determined by the amount of diastatic enzymes in the grain. Barley is the most commonly malted grain, but other grains like wheat and rye are also malted.

  • Penderyn Press Pack Nov 5Th 2018
    PENDERYN PRESS PACK NOV 5TH 2018 PENDERYN WHISKY: 100 YEARS IN THE MAKING Penderyn Whisky is made at the Penderyn Distillery which is located in the southern foothills of the famous Brecon Beacons National Park, north-west of Cardiff, and north- east of Swansea. Small stills existed in Wales in the 4th century, but the last whisky officially distilled in Wales was produced by the original, but short-lived Welsh Whisky Company at the Frongoch Distillery in Bala, North Wales, which closed in the early 1900s. Other notable characters in Wales’ whisky past include David Lloyd George, the only Welsh Prime Minister of Great Britain, who introduced the ‘3 year/1 day’ rule for whisky maturing; and Evan Williams (from Dale in Pembrokeshire) who was one of the founders of the American Bourbon industry. The idea for Penderyn was conceived by a group of friends sitting around a pub table in The Glancynon Inn in nearby Hirwaun, who decided to re-introduce the lost art of whisky distilling to Wales when they bought an un-commissioned whisky still designed by Dr David Faraday, a descendant of the famous Victorian scientist, Michael Faraday. Their dream was to create a world class single malt whisky. On Thursday 14 September 2000 the first distillation was carried out. The whisky is distilled in a unique single column still, producing a flavourful spirit at 92% abv which is married with water from the Brecon Beacons. The late great Master Distiller Dr Jim Swan came on board in 2002 and his vision helped create Penderyn’s unique style.
