A red for the last of the British barbecue weather

August in Britain rarely picks a side. The middle of the day is warm enough for the garden, then by nine the light has gone and someone's gone indoors for a jumper. The food follows the same pattern: charcoal at the weekend, something braised on the hob when the rain sets in on a Tuesday.

That's an awkward brief for a bottle. Big fruit-forward reds feel heavy under a warm sun, and light chillable reds fall apart the second a stew arrives. What you want is a wine with savoury bones and enough tang to stay lively, which is exactly the trick that Spice Route's Swartland Mourvedre pulls off.

It's a grape that spends most of its life anonymous, folded into blends to lend backbone. On its own, it becomes the most useful red in the house for this particular month.

Why savoury beats sweet in august

The thing that makes this wine work now is the tension in it. There's dark, meaty weight on one side, the kind of depth that comes from thick-skinned berries grown without irrigation, and on the other there's a bright tang of red fruit that stops the whole thing sitting heavily on a warm evening.

That balance isn't a winemaking flourish. It comes from the way Swartland summers behave: hot and dry through the day, with the Atlantic close enough to send a cooling breeze inland late on. Ripening slows, flavour builds, and the acidity holds.

So you get a red that reads as savoury rather than sweet. Which matters in August, because savoury wines cope with heat, smoke and herbs in a way that plush, jammy ones simply don't.

Bush vines that had to work for it

The vines here are unirrigated bush vines rooted in koffieklip, a hard iron-rich stone that holds heat and forces roots downwards, and Oakleaf, a sandy loam over decomposed granite. Yields land at around three tonnes a hectare. Tiny, in other words, and concentrated as a result.

In the cellar, Spice Route keeps the handling deliberately old-fashioned. Hand-picked fruit is destemmed, lightly crushed and fermented in open concrete kuipe with the cap punched down by hand, then pressed off after about a week on skins.

Ageing happens in seasoned French and American barrels rather than new ones, with a small portion resting in qvevri, the traditional clay amphorae. The point of all that is restraint: seasoned oak seasons rather than dominates, and the clay lends a quiet roundness through the middle of the palate. You taste the vineyard, not the barrel.

It's worth knowing that this corner of the Cape was written off as bulk wine country before Charles Back bought an old tobacco farm near Malmesbury and started making serious reds in a converted tobacco-drying shed. The estate's reputation was built on old vines farmed for character, and it helped drag the whole region into the conversation. If you've only met Mourvedre as the silent M in a GSM, this is the version that explains the fuss.

What to put next to it this month

Start with the barbecue, because there are still weekends left for it. A ribeye over charcoal, well crusted and then rested properly before you slice it, with a peppercorn sauce made from the pan: the wine's grip cuts through the fat and the smoke finds the savoury notes rather than fighting them.

For a long lazy afternoon with no cooking involved, put out a board of saucisson with chorizo alongside it and a wedge of aged Manchego. The cured-meat character in the glass and the cured meat on the board speak the same language, and the salt in the Manchego brings the red fruit forward.

Then there's the other August, the one with a grey sky and the windows shut. Slow-braised lamb shoulder with rosemary and garlic, pulled apart with two forks, is the pairing I'd defend in court. Oxtail stew with red wine and root vegetables does the same job for a South African household missing something familiar.

And if you're feeding people properly at the end of the month, roast duck with thyme and a dark cherry jus is the one to reach for. The cherry in the sauce lines up with the cherry in the glass, the thyme picks up the wine's dried-herb edge, and the duck fat meets a wine with the structure to handle it. Something to think about for the bank holiday, when a roast suddenly feels appropriate again.

Now, or later

It drinks well as it is. There's no waiting required, no decanting ritual you have to observe before it makes sense, and it's happy on a Tuesday next to a shepherd's pie.

But there's enough structure here to reward patience if you're inclined. Give it a few years in a cool, dark spot and the savoury, meaty side deepens, the tannins soften further, and the bright red fruit drifts slowly towards dried cherry and leather.

My own approach with a wine like this is to buy in twos: one for the grill while the weather holds, one pushed to the back of the rack to see what happens. If you usually reach for the Rhone when you want something peppery and savoury, this is the swap worth making, and the same logic applies to South African Shiraz.

If that sounds like your kind of August, the sort where the barbecue and the casserole dish are both in play, then the Spice Route Swartland Mourvedre is the 750ml bottle to have standing by. Open it with a charcoal-grilled ribeye while the evenings still allow, or hold it for a slow-braised lamb shoulder when they don't. It suits anyone who likes their reds savoury rather than sweet, and anyone curious about what a grape usually hidden in a blend can do on its own.
