How do you serve spritzes to a crowd? Batch the base, not the bubbles, with a jug planner

A spritz is the easiest drink to love and the hardest to serve to a crowd. Mixed one at a time it is bright, cold and bubbly. Mixed in a big jug an hour before the guests arrive, it is a warm, flat, orange-coloured wine. The fix is not a better jug. It is knowing which parts of the drink can wait and which cannot.

Batch the base. Never batch the bubbles.

The base is the bitter aperitivo, which keeps happily in a chilled jug. The bubbles are the sparkling wine and the soda, which stay in their bottles until the moment they go into a glass. Everything below is built on that one split.

The spec, per glass

Specs vary a little between bars, so treat 3-2-1 (three parts sparkling wine, two parts aperitivo, one part soda) as the common starting point rather than a law. A part is 30 ml here, which makes the maths easy to scale.

Why a mixed jug goes flat

Bubbles are carbon dioxide dissolved in the liquid under pressure. Pull the cork and the pressure drops; from then on the gas leaks out. It leaves faster when the drink is warm, when it is stirred or poured from a height, and when it touches ice, a rough glass or a jug wall with thousands of tiny spots for bubbles to form on.

A jug of finished spritz suffers all of that at once. You pour the wine in, stir it, stand it on a table, and then pour it again into each glass. By the second round most of the fizz has gone, and the dilution from melting ice has made it thin as well. A glass built to order keeps the bubbles because the wine goes in last, cold, down the side of the glass, with one gentle stir.

The aperitivo has no bubbles to lose. That is why it is the part to prepare ahead.

The jug planner

Set the guests, how many glasses each might have, the strength style, and how many glasses should be alcohol-free. The planner gives you the base to mix ahead and the fizz to keep sealed.

How to serve them on the night

1. Chill everything. Put the sparkling wine, the soda and the aperitivo jug in the fridge or in a bucket of ice and water well before you start.
2. Line up the glasses and fill each with ice. Ice first means the wine meets something cold straight away.
3. Pour the aperitivo from the jug: 60 ml, or a mark you have scratched on the jug's side.
4. Tilt the glass and pour the sparkling wine slowly down the inside wall. Straight down the middle makes foam and wastes the bubbles.
5. Top with the soda, give one gentle stir from the bottom, and add the orange slice.

Open one bottle at a time. A sparkling-wine stopper slows the fizz loss in an open bottle but does not stop it, so open the next only when the last one is empty. Keep a jug of water on the table too, because plenty of guests will want a glass of it between drinks.

The alcohol-free version

The same build works with no alcohol at all. Swap the bitter aperitivo for an alcohol-free bitter orange aperitif, and the wine for an alcohol-free sparkling wine or a dry sparkling juice. Soda stays soda. Serve it in the same glass with the same orange slice, so nobody has to stand out for choosing it.

Use the planner's alcohol-free setting to see the split. Some guests are driving, some are pregnant, some simply do not want a drink, and the party works better when that option looks as good as the rest. Two clearly labelled jugs make it easy for whoever is pouring.

Strength, pace and variations

A classic spritz is a long, low drink, but it is not alcohol-free: with both bottles around 11% ABV, one glass holds roughly 1.6 UK units. Two or three over an evening adds up, and the bubbles can make it drink faster than it feels. Serve food, pour 3-2-2 for a longer, lighter glass, and never let anyone drive home on the strength of "it's only a spritz".

For a different taste, change the aperitivo: a more bitter red one gives a stronger flavour and a deeper colour, and an elderflower or herbal one gives a softer, floral glass. Each works with the same planner, because the jug, the bottles and the order of pouring do not change.
