Solvay's labeling method has several parts.
1) The type of wine must be clearly written on the front label and packaging: Single Malt Scotch Whiskey, Single Grain Scotch Whiskey, Blended Scoch Whiskey), Blended Malt Scotch Whiskey, or Blended Grain Scotch Whiskey. If you are not clear about the differences between these types, malt and grain, and the various definitions of single and blended, I have written about them before. Please check them by yourself. I will not repeat the explanation here.
2) These types of nouns must strictly follow the format and cannot be used separately. The only prefix allowed is the name of the place of origin, provided that all the wine must be distilled in this place of origin. For example, you can write Islay Single Malt Scotch Whiskey, indicating that it is single malt distilled in the Islay producing area. It can also be written as Speyside Blended Scotch Whiskey, indicating that all the ingredients in this blend are distilled in the Speyside region. The law provides for the division of five production areas: Highland, Lowland, Speyside, Islay and Campeltown. Note that there is no concept of island production areas. Distilleries on these islands tend to write about a specific geographical location, for example Highland Knight can write about Orkney Single Malt Scotch Whiskey, which is allowed. Some distilleries are on the border of the Highlands and Speyside (such as The Macallan) and may be located in either Highland or Speyside.
3) If the brand name is the name of a distillery, all the ingredients must be distilled in this distillery. It is illegal to mislead consumers. This rule applies to all future new and reopened distilleries. For example, Glenfiddich is both a brand name and a distillery name, so all whiskeys bearing the name Glenfiddich must be actually distilled in the Glenfiddich distillery. For example, if IB is independently bottled, it does not need to indicate which distillery it is, but the condition is that there must be no distillery with a similar brand name to IB to prevent confusion.
4) The year label must be the oldest among all the wine components, and can only have one number. For example, a bottle of wine is a blend of 8-year-old, 10-year-old and 15-year-old wines. If you want to mark the aging year, you must write 8 years. At the same time, the aging year must be an integer, rounded down. For example, if it is aged for 10 years and 11 months, it can only be marked as 10 years. (Note that Meiwei allows the month to be indicated.) Words such as "5 to 10 years old", "up to 60 years old", "average 20 years old", and "distilled before 1991" cannot appear.
If the year of distillation (vintage) is indicated, only one specific year can appear. All component wines must be distilled within the same year indicated, and the year of bottling or aging must be clearly written. For example, Glendronach 1992 means that all wines were distilled in 1992 and must also have a vintage or bottling year. (Note that wine bottled before 2011 does not have this restriction)
