I. The Core Ingredient of Gin - Juniper Berries
Juniper, also known as European Juniper, is the only indispensable core plant ingredient in Gin production. It is distributed in Europe, Asia, North America and other regions, among which Tuscany and Macedonia are the main producing areas, and it is also widely cultivated in Serbia, Bulgaria and the Scandinavian Peninsula. It should be noted that the "juniper berries" we often refer to are not true berries, but soft scale fruits wrapped around oil-rich seeds.
The aroma of juniper is affected by factors such as year and soil, with rich and unique flavor layers: the core is a strong pine scent (derived from α-pinene), followed by the gradual release of citrus, lavender, camphor, turpentine, mixed floral notes, heather, mixed fruits and resin flavors. This complex and layered aroma runs through the entire tasting process of Gin. Brewers need to closely control the quality and characteristics of juniper to ensure the stability of Gin's aroma.
II. EU Official Definitions of Juniper-Flavored Spirits and Gin
1. Juniper-Flavored Spirits (Broad Category)
According to EU legislation Ec110-2008, juniper-flavored spirits are spirits produced by adding the flavor of juniper berries (Juniperus communis L. and/or Juniperus oxicedrus L.) to alcohol of agricultural origin, grain Baijiu or grain distillates, with a minimum alcohol by volume of not less than 30%.
During the brewing process, additional natural or nature-identical flavors, flavorings, or aromatic plants and parts thereof within the specified scope may be used, but the sensory characteristics of juniper must be clearly distinguishable, even if such characteristics are weakened in some cases.
2. Gin (Narrow Category)
The EU has a stricter definition of Gin: Gin is a type of juniper-flavored spirit that obtains its flavor by adding juniper berries (only Juniperus communis L.) to alcohol of agricultural origin that is organoleptically suitable, with a minimum alcohol by volume of not less than 37.5%. During brewing, only the specified natural or nature-identical flavors and flavorings may be used, with the core purpose of ensuring that juniper aroma is the main flavor.
Popularly speaking, the law clearly requires: Gin must be flavored with juniper and other compliant plant ingredients, with juniper flavor as the core, and the alcohol concentration at the time of bottling must not be less than 37.5%.
III. Global Classification of Gin (By Brewing Process/Producing Region)
As the world's largest category of spirits, Gin is produced in many countries around the world. Due to differences in raw materials, spices and brewing processes, a variety of sub-categories have been formed, as follows:
1. Gin (Basic Version)
Specifically refers to Gin made by adding natural flavors or legally permitted artificial flavors to alcohol, with no restrictions on coloring or sweetening.
2. Distilled Gin
Made by redistilling neutral alcohol with legally permitted natural/artificial flavors; after distillation, additional alcohol consistent with the previous ingredients or other compliant natural/artificial flavors may be added, and coloring and sweetening are allowed.
3. London Gin/London Dry Gin
Redistill high-grade alcohol in a traditional still in an environment containing only natural flavors, with the alcohol concentration after distillation reaching at least 70%; additional alcohol may be added after distillation, but the ingredients must be consistent with the previous ones. Any coloring or sweetening is prohibited, and it is one of the most popular Gin categories in the world currently.
4. American Gin
The United States has a relatively flexible definition of Gin: it can be made by distilling/redistilling malt mash, mixing alcohol with juniper and other aromatics, or using extracts of these materials; the core flavor must come from juniper berries, and the alcohol concentration at the time of bottling must not be less than 80 proof (equivalent to 40% alcohol by volume).
5. Dutch Gin (Jenever)
Specifically refers to Gin made by blending alcohol, grain wine or juniper-flavored distilled spirits (juniper flavor may not be the main flavor), and the volume of the wooden barrels used for brewing shall not exceed 700 liters. On this basis, it is further divided into two categories:
Traditional Dutch Gin: contains at least 15% malt wine per liter, with a sugar content not exceeding 20 grams;
Jonge Gin: contains no more than 15% malt wine per liter, with a sugar content not exceeding 10 grams.
6. Cologne Gin (Kölsch Gin)
Specifically refers to Gin with a malt wine content of not less than 51%.
7. Grain Gin
Brewed from 100% pure grain; on this basis, it is subdivided into Traditional Grain Gin: which must be brewed from 100% pure grain and aged for at least 1 year.
In addition to the above classifications, Gin from some producing regions has the EU Protected Designation of Origin (AOC, appellation d'origine contrôlées) qualification to ensure its quality and regional characteristics, mainly including:
Belgium: Hasselt, Balenheim, Pakerke and Oost-Vlaanderen regions;
France: Artois region in Flanders;
Germany: Coevorden region in East Frisia province.
