The Aperol Spritz has become an unexpectedly precise marker of the British summer, with new research suggesting that the nation needs only 16°C before it begins reaching for the ice, the orange slice and the familiar glow of an early-evening aperitif. According to Deliveroo, orders of the drink rise by nearly 400% when the temperature hits that modest threshold, a reminder that in Britain, summer is as much a mood as it is a meteorological event.
There is something entirely believable about that number. Sixteen degrees is not the sort of temperature that would trouble southern Europe, but here it carries a certain authority. It is enough to change plans, enough to draw people outside, enough to make the garden feel temporarily useful. Above all, it appears to be enough to persuade a great many people that the moment has arrived for an Aperol Spritz.
A small rise in temperature, a large shift in behaviour
What Deliveroo’s figures capture rather neatly is the speed with which British habits change when winter finally begins to loosen its grip. A little warmth, a little brightness and a little more confidence in the sky, and the national appetite shifts almost immediately.
That shift is visible not only in the rising popularity of the Aperol Spritz, but in the broader ritual that surrounds it. The drink has become less an indulgence than a seasonal cue, shorthand for the first park picnic, the first meal outside, the first gathering that feels as though it belongs to a different part of the year.

Suzy McClintock, VP of Consumer and New Verticals at Deliveroo said: “The moment the thermometer hits 16°C, it’s like a silent signal goes off across the nation. We’ve found that Brits don’t need a heatwave to catch those summer feelings; just a glimpse of sunshine is enough to send Aperol orders through the roof.
Whether it’s a spontaneous park picnic or the first ‘Picky Bits’ dinner of the year in the garden, we’re seeing a real shift in how people shop as soon as the winter chill lifts. With our grocery partners like Sainsbury’s and Waitrose, we’re ready to bring the summer essentials to doorsteps in as little as 20 minutes – because when the British sun actually decides to show up, you won’t want to miss the moment!”
It is a sharp observation. British summer has always involved a degree of improvisation. One does not wait for certainty. One responds to possibility.
The appetite for Aperol Spritz is spread widely across the country, from major cities to coastal favourites and prosperous commuter pockets. Deliveroo’s data identifies the following as the leading locations for Aperol orders:
Some entries are unsurprising. Brighton has long understood the value of making the most of sunlight while it lasts. London’s place near the top feels inevitable, given the city’s appetite for sociable rituals and quick-moving trends. Manchester’s inclusion is perhaps the most endearing of all, suggesting that optimism, rather than climate, remains the defining force in British summer behaviour.
The rise of picky bits and the modern summer table
The Aperol Spritz may be the headline act, but it does not arrive alone. Deliveroo’s research also points to a parallel rise in so-called “Picky Bits”, those unfussy, shareable spreads that have quietly become one of the defining meals of the British summer. Orders increase by nearly 40% once temperatures reach 18°C.
This, too, feels telling. Warmer weather does not simply change what people drink. It changes how they eat. Formal meals begin to retreat. The season favours grazing, sharing and assembling rather than cooking.
The most popular category within that spread is dips, with hummus comfortably leading the field. Cream cheese & chive, guacamole and tzatziki follow behind. Alongside them come the expected summer stalwarts: sausage and savoury rolls, olives, savoury pastries, antipasti, breadsticks and charcuterie.
Taken together, it paints a picture of a distinctly modern kind of hospitality. Fridge-to-table convenience has become part of the appeal. The point is not culinary performance. It is ease, abundance and the ability to turn a brief spell of sunshine into an occasion.
Why the Aperol Spritz fits the British summer so well
Part of the drink’s success lies in its visual confidence. The Aperol Spritz is bright, recognisable and unapologetically tied to leisure. Even in duller light, it carries the suggestion of warmth and continental ease. It makes a British terrace, balcony or patch of decking feel fractionally more glamorous than it really is.
Yet the appeal is practical as well as aesthetic. British summer is often fleeting and opportunistic. The weather improves, and people move quickly. They do not want to spend the best part of a sunny afternoon queueing for groceries or realising, too late, that they have forgotten something essential.
That is where convenience has become part of the seasonal experience. Customers can order everything needed for an Aperol Spritz, along with a full selection of summer snacks and sharing food, through the groceries section of the Deliveroo app. Supermarket partners including Sainsbury’s, Co-op, Waitrose and Morrisons, along with smaller local retailers, allow shoppers to react to the weather rather than plan around it.
A British ritual built on optimism
There is a broader cultural truth buried in all this data. Britain does not require perfect weather to behave as though summer has arrived. It requires only a glimpse of it.
That instinct is part practicality, part theatre and part hope. People know the good spell may not last. They know the clouds may be back within the hour. Still, they bring out the glasses, put together the sharing plates and sit outside as though the season has formally opened.
The Aperol Spritz has become the ideal symbol of that habit: light, social, brightly coloured and just ceremonial enough to make an ordinary afternoon feel a touch more significant.
Sixteen degrees may not sound like much. In Britain, it is apparently enough to change the menu, alter the mood and send the country in search of summer.
