Diageo – From London to the whole world

Approximately 33,000 employees are employed worldwide at Diageo, the market leader in premium spirits, with Smirnoff (vodka), Johnnie Walker (whiskey), J&B (Scotch whiskey), Baileys (liqueur), Captain Morgan (rum), Cuervo (tequila) and Tanqueray (gin), Guinness beer and branded wines. Production takes place all around the world: from Great Britain and Ireland, Italy, Spain and Africa, to the USA, Canada, Latin America, Australia, India and the Caribbean. The global corporation emerged in 1997 from the merger between Guinness and GrandMet. 180 markets around the world are handled from its London headquarters.

A lot of work and lots of attention to detail go into creating the in-depth product descriptions on Diageo’s website. Information and analysis is provided about issues ranging from detailed descriptions of the production down to the most minute ingredients. Finally, they are aware of the size of their company and also of their responsibilities as a supplier of alcoholic products. The name Diageo was also deliberately chosen – it represents their agenda. Put together from ‘dia’ (the Latin word for ‘day’) and ‘geo’ (the Greek word for ‘world’), it means that every day people are celebrating all over the world with products from their company. These products open up possibilities never dreamed of for special days and nights, marking special life events and even making the smaller things in life feel magical.

Participation in the World Spirits Award was magical: there was double gold for Tanqueray No. 10 (Spirit of the Year 2016), gold for Gordon’s London Dry Gin and Tanqueray London Dry Gin, as well as silver for Tanqueray Rangpur.

Erismann Distillery – Memories of summer and autumn

In the Erismann Distillery, good craftsmanship has been a passion and obsession for four generations. The focus is always on the product, its quality and its pleasure potential, however, there is no big secret about how it is done. Aside from fruit brandies, grappa and liqueurs, special attention is also paid to gin, whisky and rum.

Many factors determine the soul of a whisky; the right grain, the ideal yeast, the most appropriate barrel. This applies to Switzerland just as much as for Scotland. That special touch is due to the raw materials from the region and their specific flavour. The whisky matures for five and a half years in a sherry barrel. Unblended, lightly filtered and uncoloured, each batch is a limited edition. “The inspiration for gin came from our threshing floor, where a layer of hay flowers often lies. We want it to convey the character of a lush farmer’s garden.” Hans Erismann wanted an honest and simple product, fine and down-to-earth. The selected botanicals (juniper berries, barberry, bay leaves, oranges, lemons, grapefruit, liquorice, cubeb pepper, hay flowers, hyssop, elderflowers, beebalm, camomile flowers, iris root and mint) are laid individually in alcohol for a few days so that their aroma can unravel. The finished gin is combined with spring water. Ron Juan is a true rum – conceived in Zurich, made in Zurich. Selected organic molasses from Paraguay, specially developed rum yeast, some Zurich air and a large amount of Zurich spring water – this is Ron Juan.

At the World Spirits Award 2025, there was Gold for ZH Züri Gin and ZH Züri Whisky, and Silver for Ron Juan Züri Rum.

Heidebrennerei Bosselmann: Chemist and botanist, hunter and gatherer

The Heidebrennerei Distillery lies amidst the Luneburg Heath at the gateway to Hamburg. All their botanicals grow in the immediate vicinity in the largest heather biosphere reserve amidst moors and the 4,000-year-old burial mounds that characterise this rough landscape. The basis of their range is always formed by a strong hint of juniper, rounded off with a fruity body of sloe, wild blackberries and cranberries. The fresh citrus flavour of the Heidegin (heath gin) is provided by lemon balm, lemon verbena and fresh Douglas fir. Further botanicals include juniper branches and heather.

Gerhard Bosselmann and two herb ladies – the heart of the distillery – gather many ingredients themselves. Nearly all the botanicals are ground by hand to best release the essential oils. The mash is processed in stages over 72 hours and the distilling process ends at 40% to ensure an optimal taste. The gin is always unfiltered. Barrel Aged Gin is a speciality for which previously used oak and chestnut barrels are utilised.

The softest water from sources under filtering moors and sand dunes is guided over rose quartz and semi-precious stones after an ion exchange to relax it. “The distillery is a 120-litre facility, we produce the smallest batches in a London Dry Gin procedure in Germany’s purportedly smallest private gin distillery – under the motto of slow distillation at a low temperature. I am determined not to focus on quantity and profit. Only in this way can the fragile aromas release slowly, without partially dissolving the wood-body of rose hip, sloe and currant pips. Each bottle is a little work of art that is filled, sealed and labelled by hand”, as Mr. Bosselmann says.

At the World Spirits Award, there was gold for Heidegin and bronze for Master Destillerie Cut London Dry barrel aged.
