PROFITS at Inver House Distillers have plunged by nearly 20 per cent in a transitional year which saw the Scotch whisky firm reduce its reliance on bulk spirit sales and restructure its distribution arrangements in the US.

Airdrie-based Inver House reported pre-tax profits of £9.5 million for the year to December, with turnover dropping by 15.2 per cent to £67.2m largely because of falling bulk whisky sales.

The distiller, owned ultimately by Thailand’s International Beverage Holdings, said its core single malts – Old Pulteney, Speyburn, anCnoc and Balblair – had broadly shown “excellent growth” during the year.

However it highlighted slowing growth in the US, where the switch from its own distribution model to a deal with Sazerac led to a rise in operating expenses, and in Russia, where demand was affected by weak currency and depressed economic conditions.

Trading conditions were also challenging for the distiller in emerging markets such as Thailand, home country of the company’s owner.

Stripping out the US and Russia, Inver House said the value of sales generated by its single malts rose by 8.6 per cent. Old Pulteney, produced in Scotland’s most northerly mainland distillery at Wick, saw sales rise by 6.6 per cent, while anCnoc, Speyburn and Balblair saw increases of 6.6 per cent, 8.6 per cent, 9.7 per cent and 10 per cent respectively.

Away from Scotch, sales of Scottish small-batch gin Caorunn, which is made at the Balmenach distillery, grew by 65 per cent in value terms last year.

Inver House continued to invest last year to build whisky stocks for future sales and to market and promote its brands.

The investment included a multi-million project to expand its Speyburn Distillery in the north of Scotland, doubling its capacity to 4.2m litres.

Inver House had previously spent £1m to renovate its Balmenach Distillery, also in Speyside.

Managing director Graham Stevenson, who backed the industry to cope with the challenges presented to international sales by the Brexit vote, said: “Although our reported profits have fallen, our actual results are slightly ahead of expectations. 2015 was the start of a period of transition as we began to reduce our reliance on bulk and lower value products, and we took the opportunity to make significant changes to our distribution arrangements in the very important US market.

“We have strong brands which continue to grow despite difficult trading conditions in numerous markets.”
