The art of infusing fresh herbs into cocktails at The Wheelhouse

Perched beside the rotating marvel of the Falkirk Wheel, our restaurant and bar has built its reputation on more than just the view. Walk through the door and you will find a drinks list that treats herbs the way most venues treat garnishes, treating them as an ingredient rather than an afterthought. We crush, steep, muddle and shake botanicals into nearly every cocktail we pour, and we rarely reach for a bottle of pre-made syrup when a fresh sprig will do the job better.

The team behind the bar treats each glass as a small experiment. Some infusions take a week in the cool of a back fridge, others need just ten minutes of gentle warming. The constant is the leaf, the stem, the flower that arrives that morning, bright with chlorophyll and ready to give up its oils. Once you start paying attention to that, the entire cocktail list begins to read differently.

From garden to glass

We grow what we can and source what we must. Our small herb beds out the back produce thyme, rosemary, mint and a surprisingly stubborn bay laurel through the Scottish summers. When the weather closes in, our buyers step up. That is where we take notes from growers further south who treat soil like a craft, much like the Sonoma farmers who supply another kitchen we admire and who write openly about their growing methods.

The supply chain matters more than people think. A sprig of mint that has sat in a refrigerated lorry for three days loses half its aromatic punch before it reaches the bar mat. By working with growers who cut to order and courier the same morning, we keep the volatile oils, those tiny parcels of flavour that exist only in the living plant, intact. We taste deliveries before we accept them, pinching leaves and breathing them in the way a sommelier would sniff a cork.

In Australia, where a cocktail culture has exploded across laneway bars in Melbourne and rooftop venues in Brisbane, this kind of obsession with provenance is now standard. Patrons at places like Maybe Sammy or Bulletin Place expect their bartender to know the farm that grew the basil in their Southside. The same expectation is starting to travel across the world, and we are happy to meet it head on with our own transparent sourcing.

The science behind the sip

Infusion is, at heart, chemistry in a teacup. When you drop a sprig of rosemary into gin, the alcohol acts as a solvent, pulling essential oils, terpenes and water-soluble compounds out of the plant material. Time, temperature and the size of the cut all change the outcome. A bruised leaf gives up its flavour fast and dirty, while a whole sprig teases out a slower, cleaner profile that rewards patience.

We use three main methods at the bar. Cold steeping, where herbs and spirit sit together in a sealed jar for three to fourteen days, draws out the most delicate floral notes without cooking off the lighter aromatics. Hot infusion, warmed gently over a bain-marie, forces oils out faster and suits tougher herbs like sage or thyme. Fat washing, where we render a herb into clarified butter or coconut oil then shake it through a spirit, creates a velvety mouthfeel that you might recognise in some of the dessert-leaning drinks on our menu.

If you want to see how chefs play with a similar philosophy on the food side, the minestrone with pesto piece is a lovely read on how layered herb flavour works in savoury cooking. The same principles transfer directly across the bar.

Australian distillers, particularly the ones tucked into the hills around Hobart, have turned these techniques into a national conversation. Tasmanian gin, with its pepperberry and lemon myrtle accents, sits behind our bar, and the producers there treat botanical loading the way we treat our house syrups, as a daily decision rather than a fixed recipe.

Herbs we reach for again and again

Mint is the workhorse. From a classic Southside to a clarified milk punch with spearmint, the herb has the rare gift of working in every season. In summer we lean on it heavily in tall, fizzy drinks served over crushed ice. In winter we shift to darker herbs, rosemary and thyme, that hold their own against a richer plate.

Basil gets more respect than it used to. We grow Genovese in the back beds and source Thai basil from a local supplier for drinks that want a little anise lift. Pair it with gin, a touch of dry vermouth and a saline solution and you have something that tastes like a salad you actually want to drink. We have even seen Australian venues turn basil into a smoked syrup for espresso martinis, a trick we have borrowed more than once on slow Sunday afternoons.

Lavender, chamomile and elderflower round out the floral shelf. These are the notes that often appear in our Champagne afternoon tea service, where a botanical cocktail needs to play nice with delicate pastries. The trick is restraint. Too much lavender and you are drinking soap, too little and you might as well leave it out.

Then there are the wild cards. Lemon verbena shows up in summer highballs. Shiso joins the Tom Collins when we feel like straying. Pine, yes, actual pine tips collected from a friend's garden, finds its way into a winter Negroni variation that has quietly become a favourite among the steak night regulars.

Seasonal shifts on the menu

Our cocktail list changes roughly every six weeks. The cadence is set by what is growing well, what our suppliers have in stock and what the kitchen team is putting out. A bright, herby drink sitting next to a slow-braised lamb shoulder would feel like a mismatch, so we sync menus deliberately rather than letting them drift apart.

We also tie our drinks to the wider experience at the restaurant. The Wheelhouse runs an all-day kitchen, brunches that locals travel for, Friday steak nights, Sunday roasts and the Champagne afternoon tea that pulls a steady crowd from Edinburgh and Glasgow. The bar list has to flex across all of those touch points. If you want to know more about who we are and what shapes those choices, the about page spells out the philosophy of the Townhouse Restaurants group behind us.

Australian travellers, especially those who arrive via the cycle paths or the canal cruises that bring visitors to the Falkirk Wheel, often mention how much the rhythm of an all-day menu reminds them of a Melbourne cafe. The same way a good Aussie brunch spot rolls from morning eggs to evening cocktails, our venue treats daytime and evening as a single conversation rather than two separate businesses.

Pairing cocktails with food

Pairing is where herb-driven cocktails earn their keep. A drink made with thyme and lemon balances beautifully against a grilled sea bass, while a rosemary and grapefruit spritz cuts through the richness of a Sunday roast. We taste every new cocktail alongside at least three menu dishes before it goes live, and we keep a notebook of what worked and what flopped.

Brunch, in particular, is a playground for botanical drinks. A Bloody Mary with a serious celery and basil lift sits next to eggs benedict surprisingly well. A gin and tonic with cucumber and mint can hold its own against a full Scottish breakfast. If you want a closer look at how our brunch menu shapes our daytime drinks, that story on the website goes deep into the thinking.

In Australian terms, this is similar to the way a Sydney wine bar might match a Pet-Nat with a prawn roll, treating the drink as part of the meal rather than a separate event. We have learned from that sensibility, even though our produce list looks nothing like a Bondi kitchen.
