Diageo reformulates Indian spirits after flavouring action

Diageo India is preparing to reformulate several major whisky and rum brands in India following regulatory action over the use of flavouring substances, turning a dispute over product composition into a nationwide manufacturing and packaging change.

The affected products include Royal Challenge and Antiquity Blue whisky, along with McDowell’s No. 1 Celebration Matured XXX Rum. India’s Food Safety and Standards Authority has challenged the addition of flavourings intended to reproduce the characteristics of the spirit itself, including whisky flavour added to whisky and rum flavour added to rum.

United Spirits, Diageo’s Indian business, is expected to remove those flavourings from the affected recipes rather than limit changes to plants originally covered by stop-sale action. The reformulation is expected to take place across Indian production of the brands, with implementation planned over the coming months.

Temporary packaging changes are also expected while revised products move through development and manufacturing. Labels will make the presence of added flavourings more explicit during the transition, creating a packaging conversion alongside the recipe work.

The original regulatory action centred on spirits produced at particular facilities. Royal Challenge and Antiquity Blue made in Madhya Pradesh were among the whiskies affected, while McDowell’s No. 1 Celebration Matured XXX Rum produced in Maharashtra was also subject to action.

FSSAI argued that flavour derived from a spirit’s recognised ingredients, fermentation, and maturation should not be reproduced by adding a flavouring that identifies itself as the finished alcoholic drink. The regulator classified tested products as sub-standard where external artificial or nature-identical flavourings had been identified.

United Spirits initially challenged elements of the action, arguing that its products complied with applicable rules and that some of the underlying labelling questions were still being discussed with the regulator. Separate court proceedings also questioned the process used to prohibit sales of the McDowell’s rum.

Reformulation provides a more direct manufacturing route through that disagreement. Removing the disputed additives allows the company to address the composition issue without relying entirely on a prolonged legal argument over how existing rules should be interpreted.

The industrial work is less straightforward than the ingredient list suggests. A flavouring used at a relatively low inclusion level can still influence aroma, palate, consistency, and the way different spirit components are perceived in the finished blend.

Any replacement recipe therefore has to preserve a recognisable product profile while working with the remaining grain spirits, malt or Scotch components, permitted colours, water, and other ingredients. Laboratory formulation is only the first stage; the revised blend also has to remain consistent when transferred across commercial production volumes.

Royal Challenge alone is sold at more than 4.5 million nine-litre cases a year in India, according to Diageo. At that scale, even a modest formulation change affects ingredient specifications, batching instructions, quality-control references, packaging stocks, production scheduling, and distribution planning.

Several factories may also be involved in supplying the same brand. Maintaining a consistent flavour profile therefore depends on common specifications and analytical controls being applied across sites rather than solving the issue in one production facility.

The packaging transition creates a second change-control problem. Existing bottles, labels, cartons, or other printed materials may carry declarations tied to the previous formulation, while replacement artwork has to correspond with the liquid actually being filled.

Manufacturers normally manage such changes through controlled depletion of old stock and a defined conversion date. Regulatory restrictions can compress that timetable, leaving businesses to balance compliance against the cost of obsolete packaging and finished inventory.

The flavouring dispute is not the only issue bringing closer scrutiny to Indian spirits labels. FSSAI has separately challenged claims associated with maturation and the description of Scotch components in Royal Challenge, arguing that consumer-facing wording needs to reflect the characteristics of all significant components in the blend.

That widens the work beyond recipe development. Regulatory teams, production departments, procurement, quality assurance, packaging engineers, and brand managers all have to work from the same approved product specification if the revised spirits are to reach the market without another mismatch between formulation and presentation.

The case also has implications beyond Diageo. FSSAI action has involved products from other Indian spirits manufacturers, indicating that the regulator is examining practices used across the wider category rather than treating the issue as an isolated manufacturing error.

Where producers have relied on similar flavouring approaches, the resulting interpretation could trigger further recipe reviews and place additional demand on flavour houses, sensory laboratories, packaging suppliers, and regulatory teams.

For large-volume spirits, the critical measure will be whether reformulation can be completed without creating noticeable variation for consumers or interrupting availability. The manufacturing programme has to replace the disputed flavouring, qualify the revised liquid, synchronise new packaging, and convert factories and inventories while established brands continue moving through the market.

The regulatory argument began with a comparatively small entry on an ingredient declaration. Its resolution now sits in commercial-scale blending, quality control, and packaging — precisely where a wording dispute becomes an operating problem.
