    Successful bar managers know exactly what drinks their guests want and the secret sauce: extraordinary flavour fusions! That definitely describes these summer cocktails made with coffee. If they are made right, these drinks can boost your sales and give your customers a taste of sunny summer holidays.

    Evening coffee? Sleep experts may disapprove but it's an ever more popular choice. A cold brew summer cocktail made using carefully selected beans will give your customers that cool caffeine kick they long for on a warm summer's evening.

    What is cold brew coffee?

    Cold brew is coffee that has been brewed in cold water over the course of several hours resulting in particularly intense coffee flavours with little bitterness.

    The headliner on our lineup will definitely wake you up! It's the espresso and tonic. With slightly acidic, slightly bitter flavours to bring even the wallflowers out onto the dance floor. Then we have two caffeinated variations on classic cocktails: a mild and creamy black Russian and a zingy, refreshing coffee sour. Number four is fruity and fresh: the coffee bramble is ‘berry’ summery! Then the summer's best kept secret: the ‘Coffeeaner.’ This virgin cocktail will really go to your head but with no need for alcohol! With these drinks on the menu, we wish that summer could last all year.


    Coffee offers over 1,000 different flavours, making it the ideal indulgent ingredient. Depending how it is made, it can be used for its acidity, subtle or intense flavours, as a filler, a syrup or for bitter notes. The biggest challenge is making the coffee just right. Embarking on that challenge can let you in for all kinds of surprises!’

    Paying with your coffee cup

    Costa Coffee and Barclaycard have developed a device called the Clever Cup – the first reusable coffee cup that you can use to drink your coffee and make contactless payments. The Clever Cup contains a bPay chip so coffee fans can pay for their takeaway coffee simply by walking past! So far the Clever Cup is only available in the UK.

    Washing cocktail glasses properly

    Enjoying drinks means washing up. This can be a real challenge, especially with tall, delicate cocktail glasses. But it doesn't have to be. Bar owners use professional dishwashing machines to avoid watermarks, smears and damage. In this article, we bring together ‘7 tips for clean glasses’ and explain how restaurateurs should deal correctly with glasses.

    The top 5 coffee cocktails of 2019

    Espresso and tonic

    Style factor: urban and hip
    Fashion factor: top cult drink of the moment

    Ingredients and method:
    Pour 60 ml cold drip coffee (see below for recipe) and 100 ml tonic water into a shaker with a little lemon zest and mix thoroughly. If desired, garnish with an attractive curl of lemon peel. Alternative: half a slice of lime. Place one half into the glass and balance the other on the edge.

    There you have it: the cult espresso and tonic

    Homemade cold drip coffee

    You will need: 100–200 g light roast coffee beans, 1 coffee grinder, 1 cold drip coffee machine (such as the ‘Dripster’ – a device that looks a little like something from a chemistry lesson with its glass flasks), ice cubes and at least 10–12 hours.

    Pro method: grind the coffee beans as coarsely as possible. Place the ground beans in the cold drip machine and fill the container above with ice cubes. Over the course of several hours, the ice-cold water will drip onto the freshly ground beans and slowly filter through. The result is an intensely flavourful coffee extract with a variety of fruity and floral aromas which emerge.

    Cheat method: you can also brew your ‘cold drip’ coffee in a cafetière. Simply put the freshly ground coffee into the cafetière and pour ice-cold water over it. Allow to brew for several hours. Before using it, push the plunger down until the coffee grounds are squashed together.

    By the way, this method of making coffee was pioneered by the Dutch in the 17th century and is particularly gentle on the beans.

    The classic black Russian is here

    Black Russian

    Style factor: elegant and smart
    Fashion factor: new twist on an old classic

    Ingredients and method:
    First place three (or more) ice cubes in a glass. Then add 20 ml vodka, 40 ml cold brew coffee and 20 ml water. To finish, carefully top with a circle made from 20 ml cream. This one is real eye candy, no garnish required.

    Coffee sour

    Style factor: a gentleman's drink
    Fashion factor: always in

    Ingredients and method:
    Place 40 ml whisky, 30 ml lemon juice, 30 ml orange juice, 10 ml sugar syrup, 20 ml Cointreau and 60 ml cold brew coffee in a cocktail shaker and mix well for about 20 seconds. Repeat, adding ice cubes. Now pour through a tea strainer into a pre-chilled champagne glass. To finish, squeeze out and zest an orange skin over the coffee sour. Top tip: brush the edge of the glass with orange zest for an extra kick.

    Cocktail trivia

    ‘In the traditional sense, a cocktail can contain anywhere up to 90 ml alcohol. Anything more than that is a long drink.’ – Maren Meyer, bartender (Hannover)
