Wine for a picnic or a garden party: thirty guests, no fridge
A meadow, a garden, a riverbank, tablecloths and cool boxes. Thirty people, a summer afternoon, and only one real difficulty: keeping the wine cold far from any kitchen. Rosé, clairet, a dry white, ideally with screw caps. Here are the quantities, the cold chain, and an honest answer: at this size, you probably don't need a wine merchant.
The afternoon's numbers
Set for 30 guests: two and a half hours standing or sitting on the grass, 70% drinkers, because there are children and drivers, and in full sun people drink water first. “Decent” level. Half rosé, a quarter white; the last quarter, in the red column, is clairet or a light red served cool. No sparkling.
What the afternoon gets through
Setting up
The tablecloths are spread out, the cool boxes opened. Twenty-one drinkers, forty-two glasses: seven bottles, mostly rosé.
Lunch on the grass
Salads, quiches, charcuterie, cheeses. Another hour and a half, one glass an hour: five bottles, the clairet with the charcuterie, the white with everything else.
The cool box
A well-closed cool box keeps bottles at around 8 °C for four hours if it is full, two hours if half empty. That is what sets the length of the picnic, not appetite.
The raw count is 12 bottles; with the 8% margin, the calculator shows 15, by the bottle: 7 rosé, 4 white, 4 clairet. That is under the threshold of 18: it doesn't round up to full cases, and it tells you that you don't need us. At decent level, €124, a little over €4 per guest.
The cold chain without a fridge
Cold the day before, cool box full in the morning, ice on site
Cold is made at home and carried; it isn't created on the grass. The day before, the kitchen fridge takes the twelve bottles it can hold: rosé and white first, they need about three hours. The clairet, served less cold, waits in the coolest room. In the morning, everything goes into cool boxes filled to the brim, with ice packs between the bottles: a half-empty cool box warms up twice as fast.
On site, keep one cool box or closed bucket for the reserve, not opened for every glass, and a bucket of water, ice and a handful of salt for opened bottles: twenty minutes in it is enough to rescue a rosé that has been sitting in the sun. Allow a two-kilo bag of ice per four bottles, so four bags for fifteen. The detail of tubs and timings is on the page how to chill 50 bottles quickly.
Aim for the bottom of the range: white and rosé at around 8 °C out of the cool box, clairet at about 12 °C. Outside, at 28 °C, wine warms up in the glass within minutes: pour little, top up often. The page wine serving temperature gives the guide colour by colour.
How much wine for a picnic of 30 people?
Twelve bottles in the raw count for two and a half hours, 15 with the margin: seven rosé, four white, four clairet, half a bottle per guest. If the afternoon stretches into the evening, add an hour in the calculator and one more cool box. For a different number of guests, the general calculator starts from scratch.
Do you need a wine merchant for a picnic?
No, usually not. Fifteen bottles of rosé and white is a trip to the wine shop or the supermarket, sometimes cheaper, and the wine shop may even have them chilled. With this schedule, the calculator stays by the bottle up to 40 guests; it switches to full cases from 41, and then shows 24 bottles. A quote makes sense beyond that: a company or association garden party, several families ordering together. The page wine merchant, wine shop, supermarket or producer compares the four without flattery.
Why clairet, and why screw caps?
Clairet is a Bordeaux speciality, deeper than a rosé, lighter than a red: it is drunk cool and stands up to charcuterie and cold grilled meats, where a tannic red warms up and hardens in the sun. A screw cap means no hunting for the corkscrew at the bottom of a basket, and an opened bottle can be closed and laid in the ice without leaking. For a young wine to drink within the year, a cork adds nothing. The screw-cap choice depends on what is in stock: ask.
Which wine with a cold meal outdoors?
Lively, fresh wines: pale rosé with salads and tarts, dry white with cold fish and goat's cheese, clairet with charcuterie and cold chicken. The page which wine with a cold buffet goes into detail. If the picnic brings a whole building together in the courtyard, the neighbours' party page does the sums for forty people in bag-in-box.
What goes wrong outdoors
- Setting off with lukewarm bottles. A cool box keeps the cold, it doesn't create it. What isn't cold when you leave will never be cold on the grass.
- Leaving the open bottle in the sun on the tablecloth. Ten minutes is enough to warm it. It goes back in the bucket between rounds.
- Glass everywhere. Reusable cups or unbreakable glasses, and a bag to take the empty bottles home.
- Not enough water. In high summer, it is what people drink most: at least a litre per person, in its own cool box.
