Calvados

Calvados is a cider brandy from Normandy, France. Calvados is distilled from cider made from specially grown and selected apples, from over 200 named varieties. The fruit is harvested and pressed into a juice that is fermented into a dry cider. It is then distilled into eau de vie. After two years of aging in oak casks, it can be sold as calvados. The longer it is aged, the smoother the drink becomes. Usually, the maturation goes on for several years.

Calvados is different from a Hard Cider which is popular in the British Isles.

a Hard Cider is a bubbly low alcohol beverage that is often mistaken for a beer for it's carbonated nature and is not even a wine since it's fermentatation is not complete and thus it's less alcoholic and mildly sweet (since apple doesn't contain as much sugar as grapes even the semi-fermented beverage doesn't contain as much leftover sugar as a wine at s similar stage would have ) whereas a Calvados is produced by distilling a cider.

"Calvados is the regimental drink of The Queen's Own Rifles of Canada, The Royal Regina Rifles, The Royal Canadian Hussars, Le Régiment de Hull, Le Régiment de Maisonneuve, and The Sherbrooke Hussars. The troops were gifted with Calvados as the units passed through Normandy following the D-Day invasion." - Wikipedia

Grenadine

Grenadine is a common non-alcoholic pomegranate syrup with a characteristic deep red colour. It is a very popular cocktail ingredient, used for its pomegranate flavour and more for its ability to add a reddish to pink tint to a cocktail.

The name Grenadine originates from the French for pomegranate, which is grenade.

Grenadine is not subjected to regulations like alcoholic beverages are, and there are no region specific formulae any more, and thus manufacturers often replace pomegranate with blackcurrant juice and other fruit juices while retaining the same flavour profile.

Many producers now use artificial ingredients like high fructose corn syrup, water, citric acid, sodium citrate, sodium benzoate and food grade red colour along with natural and artificial flavours.

Lemon Juice

In drink mixing, fresh lemon juice brings a tangy zing to so many classic drinks and in fact, it's the most used ingredient in drink mixing other than the liquors of course.

Tequila

Tequila is a distilled beverage, made only from a specific cultivar of Agave Tequilana called 'Weber Azul' or Blue Agave, native to the states of Jalisco, Colima, Nayarit and Aguascalientes in Mexico. The Blue Agave grows above an altitude of 1500 m and are juicy succulents with spiky fleshy leaves.

Tequila is made around the city of Tequila 40 miles northwest of Guadaljara, and in the Jaliscan Highlands of Central Western Mexico. Mexican laws state that Tequila can only be produces in the state of Jalisco and a few limited municipalities in the other Blue Agave growing regions.

Tequila is 35% to 55% Alcohol by Volume (70 and 110 U.S. proof), it must be at least 40% ABV to be sold as Tequila in the USA.

Tequila is a distilled derivative of the pre-Columbian fermented beverage called pulque, made from the Agave plant. When the Spanish conquistadors ran out of their brandy, they started distilling Agave to produce a distilled spirit. This by 1600s was what Don Pedro Sánchez de Tagle, the Marquis of Altamira, began mass-producing in his distillery near modern day Jalisco and came to be known as Tequila.
