By Ellen McHale
A mouth-watering mix of juices, fruit, syrups and alcohol, co*cktails are a favourite alcoholic drink.
From tree bark to herbs, we round up theplant heroes essential to the art of co*cktail-making.
1. Fever tree (Cinchonaspp.)
An essential component in a classic gin and tonic,tonic water compliments the fruityflavour of gin and gives it a tangy taste.
The origin of this clear, fizzy liquid is theamazing fever tree.
The fever tree (Cinchonaspp.) is native to the eastern slopes of the Andeswith a range across Ecuador, Peru and Bolivia.
Contained in the bark is an alkaloid called quinine. The tree produces it to ward off insects and itgives tonic water that recognisablebitter taste.
In the 17th century, quinine was used as a fever medicinein South America. Thetree was also thought to havecurative properties and was used intreatmentfor malaria.

150ml bitter lemon
Juice of one orange (approx 150ml of juice)
Ice cubes
Method
1. Place the ice in a glass, and pour over the gin.
2. Add the bitter lemon and fresh orange juice to taste. Give it a stir, and enjoy.
2. Juniper(Juniperus)
Gin is made from a neutral spirit flavoured with botanicals (seeds, berries, roots, herbs and fruit).
Gin relies on plant ingredients to giveit flavour. Distilleries steep the neutral spiritwith botanicals to extractessential oils and achieve the delicious taste.
The most important botanical in this process is juniper (Juniperus).Ginmust contain juniper to be officially classed as a gin.
Juniperis an evergreen tree that has thin needle-like leaves. Berries from the tree are used to flavour gin. You might also use them to enhancefood disheslikecasseroles or marinades.
Common juniper(Juniperus communis)is native to the UK and Europe. OurMillennium Seed Bankhas 51collections of the UK'snative juniper trees.
With pests and diseases such asPhytophthora austrocedrithreatening juniper trees,these collections are important to preserve the nation's favourite tree seeds.
Juniper pairs well with other botanicals likelavender and eucalyptus, which we collect in the Gardens to beused inKew gin.
3. Mint (Mentha)
Mint brings afresh, zesty taste to drinks like the mojito, the ultimate refreshing co*cktail on a summer's day.
It's a versatile plant and can be grown in beds, pots and even windowsills.
To keep your plant healthy, keep cutting leaves toencourage new growth.
Like most herbs, mint is best used fresh. Thisis when the volatile oils in theleaves are at their most intense, giving a bigger flavour kick. You can also freeze mint after you pick it, as itwill help to preserveflavour.
As well as its use in cooking, mint is also used in many of our everyday products like mouthwash, toothpaste and chewing gum.
Menthol is extracted from itsessential oil andis the compound used in these products. It gives a cooling, tingling sensation as it triggers receptors in our mouths that respond to cold temperatures.
Mojito
Ingredients
Juice of 1 lime
1 tsp of sugar
Soda water
A handful of mint leaves
60ml white rum
Method
1. Mix the lime juice, sugar and mint leaves in a jug. Crush the mint leaves as you do this, which willrelease their flavour.
2. Pour into a glass and add a handful of ice.Pour in the rum and mix.
3. Top with soda water and a mint garnish.
4. Coffee (Coffea)
Not just for breakfast, coffee is used in a variety of popular boozy co*cktails like the espresso martini.
The coffee beans we're familiar with are actually the roasted seeds of coffee (Coffea) plants.
Coffee beans go on an epic journey from plant to cup, as they go through a lengthy sorting, drying and roasting process.
Whilst there are 124 species of coffee, Coffea arabicais the most widely used. It is a small tree that grows between 2m and 8m, withevergreen leaves, white flowers and red fruits.
Scientists at Kew have found that wild arabica coffee is endangered, mainly because ofdeforestation, climate change, and the spread of diseases.
Our research intowild species of coffeeand how to protect themcould help us develop a tasty cup of coffeethat supports both livelihoods and protects one of the world's most popular drinks.
Espresso martini

5. Pomegranates(Punica granatum)
Pomegranatesare a secret ingredient in manyco*cktails.
These bright red fruits are behind a syrupcalled grenadine, which is used in co*cktails like Tequila Sunrise. The syrup is made from the fruit's juice and sweetened with sugar.
Native to Middle Eastern countries like Afghanistan, Iran and Pakistan, the pomegranateplant is a large shrub or small tree that hasevergreen leaves and bright orange flowers.
The round fleshy fruit of the pomegranate plant contains two layers. The outer, hard later is called an epicarp, and the inner soft layer is called a mesocarp.
The inner mesocarp forms distinctchambers containing seeds with a fleshy covering. These are the seeds we buy in the supermarket to eat and add to dishes like salads and couscous.

Fever Tree (Cinchona spp.): Tonic water, a quintessential ingredient in a classic gin and tonic, owes its distinct flavor profile to quinine derived from the bark of the fever tree (Cinchona spp.). The tree, indigenous to the Andes, contains quinine—an alkaloid that gives tonic water its bitter taste. Historically, quinine was used as a fever remedy and in the treatment of malaria.
-
Juniper (Juniperus): A crucial botanical in gin-making, juniper berries lend their signature flavor to gin, being a mandatory ingredient for its classification. These berries, obtained from the juniper tree, notably Juniperus communis in the UK and Europe, are also used in culinary applications to enhance dishes like casseroles and marinades.
-
Mint (Mentha): Known for its fresh, zesty taste, mint is a versatile herb used in co*cktails such as the Mojito. Its volatile oils contribute to its intense flavor, making it a popular choice in both culinary and everyday products like mouthwash and chewing gum.
-
Coffee (Coffea): Coffee beans, obtained from Coffea plants, aren't solely reserved for morning beverages. They are employed in co*cktails like the espresso martini. Coffea arabica, the most widely used coffee species, faces endangerment due to deforestation and climate change, emphasizing the importance of conservation efforts.
-
Pomegranates (Punica granatum): These vibrant fruits yield grenadine syrup, a key ingredient in co*cktails like the Tequila Sunrise. Originating from Middle Eastern countries, the pomegranate plant bears a significant cultural and culinary legacy, celebrated in traditions such as Yalda Night.
Each ingredient listed plays a pivotal role in the diverse array of co*cktails, offering distinct tastes, aromas, and cultural significance, while also highlighting the intertwined relationship between plants, beverages, and human traditions.
