A mixed case of wine is a dozen (or six) different bottles sold as one box — and, done properly, it’s a merchant’s argument. This red because Tuesday needs one; this white because your table leans to fish; this slightly dearer bottle because your palate is ready for it. Every case I build makes a case, if you’ll forgive me, and that’s the thesis of this whole page: a good mixed case argues, a bad one just clears shelves — and you can audit the argument in about five minutes. I sell more mixed cases than anything else in the shop, and I also get asked to justify them more than anything else, usually by someone holding two cases side by side and doing sums in their head. So what follows is my own checklist, handed over so you can use it on anybody’s case — mine included.
What’s actually inside a mixed case of wine
Nothing mysterious, physically. It’s the same cardboard (or, for serious stuff, timber) as a straight case — the wine trade has always packed its stock in cases rather than crates, unlike beer or milk, and a mixed case of wine just varies what’s in the dividers.
What should be inside is a set of jobs, each bottle hired for one. A crisp Picpoul for the Friday fish. A Côtes du Rhône for shepherd’s-pie weather. A Rioja Crianza for the Sunday roast, a Sauvignon for the friend who only drinks Sauvignon, and something a bit more serious — a village Burgundy, say — for the weekend that deserves it. When I pack one, I can tell you why each bottle is there; that’s the whole difference between assembly and argument.
The lazy version exists too, in numbers: whatever didn’t sell last month, bundled together and called a “selection.” Both kinds sit on the same shelves looking identical from the outside. Telling them apart is most of this article, and it’s a skill that pays for itself with the very first case you buy.
What is a case of wine called?
It’s called a case — not a crate, not a box, though people say both. The wine trade has kept “case” as its working unit for as long as merchants have shipped bottles by the dozen, and it sticks precisely because a case is a defined trading quantity, not just a container.
Within that, you’ll hear “mixed case” for an assorted selection, and sometimes “split case” in the trade when a merchant divides one standard case across two customers. A mixed wine case, in plain terms, is just a case where the bottles differ rather than repeat. Nothing more exotic than that — I’ve heard people expect some special legal category, and there isn’t one.
Is a case of wine 6 or 12?
Both, and the trade uses both deliberately rather than by accident. Twelve bottles has long been the default trading unit across most of the wholesale market; six has become more common as fine wine prices have risen, letting merchants (and customers) buy serious bottles without committing to a dozen at once. Neither is “wrong” — they serve different jobs.
There’s a genuine trade-off worth knowing, not just trivia:
| Case size | Why it exists | Trade-off |
|---|---|---|
| 12 bottles | The long-standing default trading unit | Less packaging per bottle — the more sustainable option |
| 6 bottles | Long favoured by the German wine trade; growing elsewhere as fine wine prices rise | More packaging per bottle shipped |
| Half case (6, sold as a subset) | Lets you try a producer or region without a full dozen | Sometimes a smaller discount than the full case gets |
Fine wines built for long ageing are often still shipped in wooden cases — usually rough pine, branded with the producer’s mark burned or stencilled on the end — because they hold up better over years in a cellar than cardboard does. Everyday mixed cases don’t need that; cardboard with proper dividers, from a merchant who actually cares about breakage, does the job fine for wine you’ll drink this year. The practical takeaway: pick the size that matches how fast you actually drink, not the one with the bigger discount sticker.
What is a half case of wine?
Six bottles make up a half case, which sounds like a technicality until you’re actually deciding what to buy. I tend to suggest it to anyone dipping a toe into unfamiliar territory — a producer they’ve only read about, a style they’re curious but not committed to — because it’s enough to form a real opinion without the financial or storage weight of twelve. It also happens to be the sweet spot for gifting: substantial enough to feel like a proper present, small enough that nobody’s rearranging their hallway to fit it.
It’s also handy for splitting interests within one household: three reds and three whites, say, rather than committing a full twelve to one style. If you’re planning for other people rather than yourself, our guide on wine gifts that land: choosing for someone else goes into sizing gifts properly — a half case sits in a nice spot between “bottle” and “showing off.”
How a merchant actually judges value in a mixed case
Here’s the direct answer, then the reasoning behind it. A mixed case is good value when the bottles inside earn their place individually — not padded with filler to hit a price point — and when the case as a whole costs less, or delivers more, than buying each bottle alone. Cheap isn’t value; value is a case where every bottle would justify its price sold on its own.
That distinction trips people up constantly, and it took me a long while to explain it well rather than just insisting on it. Trade writers have made the same point with fine wine: a bottle costing three times another isn’t automatically three times better — sometimes it’s simply scarcer, or from a more fashionable commune, and the quality gap is real but modest. The same logic runs straight through mixed cases at every price point.
What I actually check, in order:
- Who chose it. A case put together by staff who taste the range and know it — the kind of hand-selling a specialist shop is built around — differs completely from a generic assortment stacked to move volume.
- Whether it’s padded. Watch for the same house style repeated under three different labels. It happens, particularly with own-label bulk wine sold cheap.
- The bottle-by-bottle maths. Add up what each wine costs on its own, then compare to the case price. If the saving is thin once you do that, the “discount” is mostly marketing.
- Whether it’s fresh stock. Reliable merchants, quick shipping and genuinely good vintages inside the case matter more than the headline percentage off — a discount on tired stock isn’t a discount.
Four checks, one breath: who chose it, what’s padding it, what’s the real maths, how fresh is the stock. Any mixed case in the country can be judged on those four, in about five minutes.
A well-built mixed case will sometimes include something like a Bordeaux second wine sitting next to a village-level Burgundy — different price points doing different jobs in the box. If that pairing logic interests you, I’ve written more on it in second wines: how to drink a great château without the grand vin price. For the fuller picture on reading labels and scores before you buy anything, start with how to buy wine like a merchant: labels, ratings and value. And as a rough shape for a first case: most of it in the everyday-but-honest band, one or two bottles that stretch your palate, and nothing that’s only there to hit a price.
Getting the most from a mixed case once it arrives
The case’s argument only lands if you actually listen to it, so give it three habits. First, spread it: open the bottles across a few weeks rather than one evening — six different wines teach you more about your own taste than twelve of the same, but only if each gets its own dinner rather than a crowded Saturday. Second, compare: when two bottles in the case share something — two reds, two whites, two takes on the same region — open them on consecutive nights and notice what’s different. That’s where the education hides. Third, take one note: which bottle would you reorder? That single line is the most useful thing you can hand a merchant next time, and it turns your second case from a guess into a fitting.
There’s a hosting use too. If you’re planning for a dinner party rather than restocking your own rack, a mixed case is often the easiest way to cover courses without buying six separate bottles individually — reds, whites, something with a bit of sweetness for the end. Our hosting without stress: planning wine for a dinner party guide walks through matching a case to a menu properly.
Questions customers ask us
Which wine is best for diabetics? That’s genuinely a medical question, and I’d rather send you to a GP or pharmacist than guess. If you want a steer on dry, lower-sugar styles for other reasons — taste, mainly — just ask when you’re in, that part I can help with.
Does a mixed case ever cost more than buying bottles separately? Occasionally, yes — usually when it includes something rare that the merchant has priced to reflect scarcity rather than volume. Always worth the quick maths above before assuming a case is automatically cheaper.
Can I ask a merchant to build a mixed case for me? Most will, especially specialist shops rather than supermarkets — tell them your budget and what you already like, and let them use their palate rather than a spreadsheet.
The merchant’s last word
I’ll be honest — I sold mixed cases badly for years, just bundling whatever needed shifting and calling it a “selection.” A good one argues: every bottle with a job, every job worth doing, nothing there just to hit a price. Now you’ve got the checklist, run it on anything I put in front of you — that’s exactly how I’d want to be shopped. When you’re ready to build one properly, come and browse the Red cellar — tell me your week’s menus and your budget, and I’ll make the argument bottle by bottle.
