The Tzatziki Martini: The Most Surprising Cocktail in Edinburgh Arrives Crystal Clear

There is a particular moment that happens at Nectar when the Tzatziki Martini arrives at a table for the first time.

The glass is completely clear. Not pale yellow the way a gin martini is clear, and not cloudy the way you might expect something containing yogurt and cucumber and dill to look. Crystal clear. The kind of clarity that makes you hold it up to the light to confirm that something is actually in the glass.

Then you take the first sip.

The flavour arrives in a sequence that takes a second or two to fully register. Something herbal and botanical first, the gin making itself known. Then the cucumber, fresh and clean. Then the dill, quiet but present. And then, from somewhere unexpected, the garlic: not sharp or aggressive but rounded and warm, integrated into everything around it in a way that makes the whole drink feel more cohesive and more savoury than the glass suggested it would be. It finishes dry and precise, the way a good martini should finish, with a length that lingers.

At that point most people look at the glass again. The visual information and the flavour information are telling them completely different stories, and the gap between the two is exactly where the Tzatziki Martini lives.

I think it is the most interesting cocktail on the Nectar menu. It is not always the most ordered, because the name asks more of a first-time visitor than the Warmth Within or the Drops of the River do. But it is consistently the one that produces the strongest reaction from the people who order it, and it is the cocktail that most directly represents what the whole drinks programme at Nectar is trying to do.

Where the idea comes from

Tzatziki is one of the oldest and most ubiquitous condiments in the Greek culinary tradition. It appears in versions of the dish going back centuries, rooted in the broader tradition of yogurt-based sauces that run through Turkish, Iranian, and eastern Mediterranean cooking. The specific combination of strained yogurt, cucumber, garlic, dill, and olive oil that most people recognise as tzatziki has been part of the Greek kitchen for generations, served alongside grilled meat, as a dip for bread, as a condiment for souvlaki, and as the cooling element that balances the heat and richness of everything it sits beside.

The logic of translating that flavour profile into a cocktail is not as strange as it first sounds. The components of tzatziki are all aromatic: cucumber is herbal and fresh, dill is distinctive and slightly anisic, garlic in its cooked or mellowed form has a warmth and depth that is far removed from the sharpness of raw garlic, and yogurt provides a creamy, slightly acidic backdrop that brings everything together. These are flavour qualities that spirits and vermouth can carry. The question is how to carry them in a way that creates something genuinely excellent rather than merely novel.

The answer at Nectar is the process. And the process is the story of this cocktail.

Why Gin Mare is the only possible base

The starting point is Gin Mare, and the choice is not arbitrary.

Gin Mare is a Spanish gin produced in a Gothic chapel in the small fishing village of Villanova i la Geltrú on the Catalan coast. Its name comes from the Latin Mare Nostrum, meaning Our Sea, the ancient Roman name for the Mediterranean. The botanical profile is built entirely around Mediterranean ingredients: Arbequina olives from Catalonia, fresh basil from Italy, thyme from Greece, and rosemary from the Spanish coastline, alongside the more traditional gin botanicals of juniper, cardamom, coriander, and citrus peel.

The result is a gin that smells and tastes like the Mediterranean in a way that is specific and unmistakable. It has a savouriness from the olive that most gins do not have. It has an herbaceous quality from the basil and thyme that sits naturally alongside fresh herbs. It has a particular warmth and earthiness that makes it significantly more food-friendly than a classic London Dry gin, which is why it appears elsewhere on the Nectar menu in the Spring Spritz special, where its botanical character works naturally alongside basil, honey, and elderflower.

Using a standard gin in the Tzatziki Martini would produce a version of the drink. Using Gin Mare produces the drink, because the gin's existing Mediterranean botanical character aligns with the tzatziki flavours being introduced rather than competing with them. When the cucumber and dill and garlic arrive in the infusion, they are joining a flavour conversation that the gin has already started rather than starting one of their own.

The infusion: 24 to 48 hours of patience

The Tzatziki Martini begins days before it is served. That is the part of the process most guests never see and the part that makes everything else possible.

Fresh garlic, cucumber, dill, and Greek yogurt are combined with the Gin Mare and left to infuse for between 24 and 48 hours. This is not a quick infusion done in the hour before service. The spirit sits with the ingredients long enough for the flavour compounds to fully bond with the alcohol molecules rather than simply existing alongside them.

The distinction matters enormously. When you add a fresh ingredient to a spirit for a short period, you get the surface flavours: the immediate top notes of cucumber, the sharp brightness of fresh dill, the aggressive raw quality of garlic. These are the obvious, first-impression flavours that would produce a drink that is interesting for two sips and tiring by the third.

A 24 to 48-hour infusion goes deeper. The alcohol has time to pull the secondary and tertiary flavour compounds from each ingredient, the compounds that are responsible for depth and complexity rather than immediate impact. The garlic mellows from sharp and aggressive into something rounded and warm. The cucumber moves from simple freshness into a more nuanced, slightly earthy register. The dill develops a complexity that goes beyond its most obvious anisic note. The yogurt contributes its lactic quality, its slight acidity and creaminess, into the body of the spirit itself.

By the end of the infusion, the Gin Mare has been permanently changed. It no longer tastes only like Gin Mare. It tastes like something that grew in a Greek kitchen over a long afternoon, which is precisely what tzatziki tastes like at its best.

The clarification: turning something cloudy into something clear

After the infusion, the liquid is cloudy. Greek yogurt will do that to anything it touches: the proteins and fats in the dairy scatter light and produce the opaque, milky appearance that anyone who has stirred yogurt into a sauce will recognise.

Clarification is the process of removing that cloudiness while keeping everything that causes the flavour.

The technique used at Nectar is milk punch clarification, one of the oldest and most effective clarification methods in cocktail making. Despite the name, the process at Nectar does not add additional dairy. The milk punch method works by introducing an acid, in this case the natural lactic acid already present in the yogurt itself, to cause the proteins in the liquid to coagulate and bind with the particles responsible for cloudiness. As those protein chains form and clump together, they trap the physical matter that is scattering light: the fine particles of yogurt solid, the tiny fragments of cucumber and dill, the microscopic elements that the naked eye reads as cloudiness.

The coagulated proteins are then strained out through increasingly fine filters. What is left behind is a liquid that is completely clear under light but retains every volatile flavour compound that was present before clarification. The aromatic molecules, the flavour-carrying compounds, the essential qualities of the cucumber and dill and garlic and yogurt: these are soluble and remain in the liquid. The cloudiness, being physical rather than chemical, is removed with the coagulated proteins.

The science of this process was understood in some form by Georgian-era punch makers who used milk to clarify their preparations centuries before the technique was applied to cocktails. Iain McPherson at Panda and Sons, whose own innovations including Densing we have written about on this blog, has been one of the most influential figures in bringing these historical techniques into modern bar practice. The clarified Tzatziki Martini is Nectar's most direct expression of what that tradition produces when it is applied to a genuinely distinctive flavour concept.

Noilly Prat and the martini structure

Once clarified, the infused and clarified Gin Mare is mixed with Noilly Prat dry vermouth in the proportions of a classic dry martini.

Noilly Prat is a French dry vermouth produced in Marseillan on the Languedoc coast, aged in oak barrels outdoors in the Mediterranean sun before blending. It is drier and more herbaceous than Italian dry vermouths, with a slightly oxidised, almost nutty quality from the outdoor ageing that gives it more complexity than fresher, more neutral vermouths. It is the most classical choice for a dry martini and it is the right choice here for a specific reason: its own herbal and slightly savoury character aligns with the botanical profile of the infused Gin Mare without either element dominating the other.

The result is a drink that has the precise structure of a classic dry martini: the gin-vermouth relationship, the dry finish, the elegant clarity in the glass. But the gin is no longer simply gin. It has been transformed by the infusion and clarification process into something that carries the full flavour architecture of tzatziki within a spirit that already spoke the same culinary language.

Stirred, not shaken. Cold, precisely measured, served in a chilled glass. Everything a martini should be, containing everything a tzatziki should contain, looking like neither of them.

What it teaches you about cocktail making

The Tzatziki Martini is the cocktail that most directly expresses the philosophy behind the drinks programme at Nectar. The underlying idea has always been that Greek and Mediterranean flavour provides a genuine creative framework rather than a superficial theme: ingredients and combinations that have been developed across centuries of culinary tradition and that carry real depth when they are properly understood and properly handled.

The tzatziki concept works as a cocktail not because someone decided to make a novelty drink with yogurt in it. It works because the flavour components of tzatziki, cucumber, dill, garlic, yogurt, are genuinely aromatic and genuinely complex, and because the technique exists to carry those components into a spirit without losing their character or their coherence. The clarification is not a trick to make the drink look impressive. It is the necessary step that makes the drink work: without it, the yogurt proteins would make the liquid undrinkably thick and visually unappealing. With it, the drink can be precisely what it sets out to be.

There is also something worth noting about the relationship between the cocktail and the food it sits alongside. The chicken skewer is the most natural pairing on the menu, and the reason is direct: tzatziki is the traditional accompaniment to souvlaki in Greece, and the Tzatziki Martini is tzatziki in a glass. Drinking one alongside the other is the most explicitly Greek combination available at the bar, and it consistently produces a moment of recognition at the table when people make the connection.

The cheese filo pastry also works well alongside it. The saltiness and richness of the melted feta provides a grounding for the herbaceous, savoury quality of the cocktail, and the honey on the pastry creates a sweetness that makes the dryness of the martini feel more structured rather than austere.

The reaction that never gets old

I have watched this cocktail arrive at a lot of tables now. The reaction is different to the reaction that other drinks produce. The Warmth Within produces pleasure: the heat arrives, the complexity builds, people enjoy it. The Mountain Chalet produces satisfaction: warm, spirit-forward, the right drink at the right moment. The Tzatziki Martini produces something closer to genuine surprise.

The visual information says one thing. The flavour says another. The gap between those two experiences is where something interesting happens, and that particular quality, of a drink that teaches you something about what a cocktail can be, is not something that any amount of technique produces on its own. It requires an idea that is genuinely worth exploring in the first place.

The Tzatziki Martini is that idea. It has been on the menu since we opened and it will remain on the menu for as long as Nectar exists, because it is the cocktail that most completely answers the question of what this bar is trying to do.

Book a table at Nectar Bar and order it before you have decided whether it sounds like something you would enjoy. That is exactly the right moment to try it.
