Alcoholic spirits measures are instruments designed to measure exact amounts or shots of alcoholic spirits.
The most common products used today to measure spirits are the thimble measure and the non-drip measure, often referred to as an optic. The terms Optic, Optic Pearl, OpticJade and OpticOpal are all trademarks of Gaskell & Chambers owned by the company IMI Cornelius (UK) Ltd, [1] but the word “optic” has become synonymous with inverted or non-drip spirit measures. Other manufacturers, such as Beaumont TM, also supply this type of measuring device. [2]
The optic or non-drip measure is mounted beneath an inverted spirit bottle, so that a pre-defined volume of the bottle's contents drains into the measure. Lifting a lever on the side of the measure first closes off the measure from the bottle, then dispenses the measured liquid into the glass or mixing vessel held underneath. This mechanism ensures that a correct spirit measure can be dispensed each time, as the inverted bottle allows the measure to be replenished in the optic after each shot has been dispensed. These types of measures are commonly used for highly demanded drinks in professional bar settings, and are often incorporated into visually-appealing machines that serve both functional and marketing purposes for the liquor being poured. Bottles are available to the trade with their labels affixed upside down so that they will be the right way up when mounted on the optic.
The thimble measure is a stainless steel vessel, like a shot glass, either with predefined measuring lines etched or stamped into the sides, or else pre-sized so that pouring up to the brim of the measure yields the correct volume. This second variation is commonly seen in a double-thimble or "hourglass" form, with two metal cups of different volumes (often in a 3:2 or 2:1 ratio, like a U.S. standard 1.5 fl oz "jigger" and 1 fl oz "pony", or UK standard 25/50mL or 35/70mL combos) spot-welded to each other at their relative bottom surfaces, possibly with a handle between them, allowing one unit to easily measure two common volumes.
Thimble measures are popular for home use, as they allow a relatively untrained person to pour quickly and accurately from several bottles without risking cross-contamination between them, or requiring the purchase, use and cleaning of a pour spout for each bottle as would be seen in a professional bar.
Common in U.S. bars, these devices consist of a simple rubber or plastic stopper with a metal or plastic tube fitted into it, and often a second smaller tube extending down into the bottle, designed to replace the cap or cork on a bottle of liquor. The spout, in the U.S., is usually calibrated to allow a flow of 1 fluid ounce per second, so that a bartender can measure accurate and consistent shots of liquor or portions for cocktails based on timed pours, without needing to use a jigger or other measuring device. [3]
Common in U.S. bars, these devices appear visually to be the same as a free-flow pour spout, but have an internal mechanism to block the tube after a pre-defined and calibrated volume of liquid has passed, oftentimes a set of 2 or 3 balls. Because of the geometry, the bottle with one of these spouts needs to be held at a specific angle, typically 45 degrees, otherwise the volume poured will be under or over the stated calibration.
Common in France, where it is called a bouchon doseur boule, this device consists of a transparent T-shaped glass tube arrangement, [4] with a ball on one end of the horizontal section, a cap or cork on the other end, and a cork or plastic bottle stopper on the bottom of the T, allowing the measure to replace the cap of a liquor bottle. In use, the bottle is inverted until the ball fills with liquor, and then tilted in the other direction to let the liquor pour out the spout in a manner that keeps additional liquor entering the measure from the bottle.
The Weights and Measures Act of 1963 made it illegal in Britain for businesses to give short weights or short measures to consumers. Before this there was no legislation, only guidelines as to the correct weight of an alcoholic spirit measure, and if spirit measures or optics were used, they required a government stamp to certify that the measure was accurate. This act specified that only gin, rum, vodka and whisky were spirits and had to be served in the prescribed measured quantities using an approved optic measure. All other drinks are not spirits (for the purposes of the act) and could be free poured. Today, these other drinks may not be free poured, but must be measured, though the bar is free to choose the size of the measure (which must be advertised). In practice, most bars will use the same size measure as for the four spirits. [5]
The 1963 act formalized the legal measures by which spirits and other alcoholic beverages should be dispensed, namely 1⁄4, 1⁄5 or 1⁄6 gill (36, 28 or 24 ml), but this was replaced in 1985 when 25 ml or 35 ml were permitted. [5] Landlords have the option to decide which quantity they sell, with the difference being caused by historically larger measures being used in Scotland and Northern Ireland. The landlord can choose one or the other but not both.
Thimble measures are also used in 175 ml and 250 ml volumes for measuring wine. Although government stamped for the correct volume, the thimble measure does rely on the user measuring the wine out manually into the thimble.
Units of alcohol are used in the United Kingdom (UK) as a measure to quantify the actual alcoholic content within a given volume of an alcoholic beverage, in order to provide guidance on total alcohol consumption.
An alcopop is any of certain flavored alcoholic beverages with relatively low alcohol content, including:
A liqueur is an alcoholic drink composed of spirits and additional flavorings such as sugar, fruits, herbs, and spices. Often served with or after dessert, they are typically heavily sweetened and un-aged beyond a resting period during production, when necessary, for their flavors to mingle.
Alcohol proof is a measure of the content of ethanol (alcohol) in an alcoholic beverage. The term was originally used in England and was equal to about 1.8 times the percentage of alcohol by volume (ABV). The UK now uses ABV instead of proof. In the United States, alcohol proof is defined as twice the percentage of ABV. The definition of proof in terms of ABV varies from country to country.
A wine bottle is a bottle, generally a glass bottle, that is used for holding wine. Some wines are fermented in the bottle while others are bottled only after fermentation. Recently the bottle has become a standard unit of volume to describe sales in the wine industry, measuring 750 millilitres. Wine bottles are produced, however, in a variety of volumes and shapes.
A shot glass is a glass originally designed to hold or measure spirits or liquor, which is either imbibed straight from the glass or poured into a cocktail. An alcoholic beverage served in a shot glass and typically consumed quickly, in one gulp, may also be known as a "shooter".
A standard drink is a measure of alcohol consumption representing a hypothetical beverage which contains a fixed amount of pure alcohol. A standard drink varies in volume depending on the alcohol concentration of the beverage, but it always contains the same amount of alcohol and therefore produces the same amount of drunkenness.
A closure is a device used to close or seal a container such as a bottle, jug, jar, tube, or can. A closure may be a cap, cover, lid, plug, liner, or the like. The part of the container to which the closure is applied is called the finish.
A keg is a small barrel.
Liquor is an alcoholic drink produced by distillation of grains, fruits, vegetables, or sugar, that have already gone through alcoholic fermentation. Other terms for liquor include: spirit drink, distilled beverage or hard liquor. The distillation process concentrates the liquid to increase its alcohol by volume. As liquors contain significantly more alcohol (ethanol) than other alcoholic drinks, they are considered "harder" – in North America, the term hard liquor is sometimes used to distinguish distilled alcoholic drinks from non-distilled ones, whereas the term spirits is used in the UK. Examples of liquors include brandy, vodka, absinthe, gin, rum, tequila, and whisky.
A liquor store is a retail shop that predominantly sells prepackaged liquors – typically in bottles – usually intended to be consumed off the store's premises. Depending on region and local idiom, they may also be called an off-licence, off-sale, bottle shop / bottle-o liquor store (US) or other similar terms. Very limited number of jurisdictions have an alcohol monopoly. In US states that are alcoholic beverage control (ABC) states, the term ABC store may be used.
Wine accessories are things that may be used in the storage or serving of wine. Wine accessories include many items such as wine glasses, corkscrews, and wine racks.
Various unique terminology is used in bartending.
Absinthe is an anise-flavoured spirit derived from several plants, including the flowers and leaves of Artemisia absinthium, together with green anise, sweet fennel, and other medicinal and culinary herbs. Historically described as a highly alcoholic spirit, it is 45–74% ABV or 90–148 proof US. Absinthe traditionally has a natural green color but may also be colorless. It is commonly referred to in historical literature as la fée verte. It is sometimes mistakenly referred to as a liqueur, but is not traditionally bottled with added sugar and is, therefore, classified as a spirit. Absinthe is traditionally bottled at a high level of alcohol by volume, but it is normally diluted with water before being consumed.
An alcoholic beverage is a drink that contains ethanol, a type of alcohol that acts as a drug and is produced by fermentation of grains, fruits, or other sources of sugar. The consumption of alcoholic drinks, often referred to as "drinking", plays an important social role in many cultures. Most countries have laws regulating the production, sale, and consumption of alcoholic beverages. Regulations may require the labeling of the percentage alcohol content and the use of a warning label. Some countries ban such activities entirely, but alcoholic drinks are legal in most parts of the world. The global alcoholic drink industry exceeded $1 trillion in 2018.
A fifth is a unit of volume formerly used for wine and distilled beverages in the United States, equal to one fifth of a US liquid gallon, or 25+3⁄5 U.S. fluid ounces ; it has been superseded by the metric bottle size of 750 ml, sometimes called a metric fifth, which is the standard capacity of wine bottles worldwide and is approximately 1% smaller.
A well drink or rail drink is an alcoholic beverage served using the lower-cost liquors stored within easy reach of the bartender in the counter "speed rail", "speed rack", or "well".
A miniature is a small bottle of a spirit, liqueur or other alcoholic beverage. Their contents, typically 50 ml, are intended to comprise an individual serving.
Geist is a distilled beverage obtained by maceration of unfermented fruit or other raw materials in neutral spirits, followed by distillation.
