As an expert sommelier and brewer, I can provide a detailed answer to the question: What is the difference between Pimm's No. 1 and Pimm's No. 2?
Pimm's No. 1 Cup, also known as Pimm's Cup, is the most popular version of Pimm's and has been enjoyed since 1840. It is a gin-based drink with a base that is bottled at 25% alcohol by volume. The gin used in Pimm's No. 1 gives it a distinct flavor profile and contributes to its popularity as a refreshing summer cocktail.
Pimm's No. 2 Cup, on the other hand, was introduced in the 1930s and was based on Scotch whisky. Unlike Pimm's No. 1, which is gin-based, Pimm's No. 2 had a different base spirit. However, the use of Scotch whisky in Pimm's No. 2 was phased out in 1970 by the new brand owners, The Distillers Company.
The difference in base spirits between Pimm's No. 1 and Pimm's No. 2 is the most notable distinction between the two versions. While Pimm's No. 1 is centered around the botanical and juniper flavors of gin, Pimm's No. 2 had a unique character derived from the smoky and rich flavors of Scotch whisky.
It is important to note that Pimm's No. 2 is no longer available as it was discontinued by The Distillers Company. This makes Pimm's No. 1 the only remaining and widely popular option for Pimm's enthusiasts.
In terms of taste, Pimm's No. 1 has a light and refreshing flavor with hints of citrus, spices, and herbs. The gin base provides a crisp and clean taste, making it a perfect choice for summertime sipping. Pimm's No. 2, with its Scotch whisky base, would have had a more complex and robust flavor profile, with the smoky and malty notes of the whisky shining through.
While I have not personally tasted Pimm's No. 2 since it was discontinued before my time, I have had the pleasure of enjoying Pimm's No. 1 on numerous occasions. Its unique blend of flavors and the versatility to be mixed with various fruits, herbs, and mixers make it a delightful drink for any occasion.
The main difference between Pimm's No. 1 and Pimm's No. 2 lies in their base spirits. Pimm's No. 1 is based on gin, while Pimm's No. 2 was formerly based on Scotch whisky. The discontinuation of Pimm's No. 2 makes Pimm's No. 1 the sole and popular choice for Pimm's lovers.
