In its latest annual accounts the Aberdeenshire firm said its ice-cream volumes had fallen 15% as a result of the wet summer in 2012.
The ice cream division recorded turnover of almost £9.3 million in the 12 months to May 31, 2013, but that was lower than the £10.4m from the previous year.
Farming revenue improved from £454,000 to almost £508,000 while wind turbines was steady at £518,167.
According to the accounts the turnover from the company's joint venture crisp business was down from more than £120,000 to just short of £29,000.
In total, turnover dropped by 11% from £11.5m to £10.3m.
Along with the lower sales family owned Mackie's also had to cope with higher ingredient costs and it highlighted a 40% increase in cream prices.
Operating profit for the 2013 financial year came in at £244,761, compared to £391,000 in the previous year.
Writing in the accounts the directors said: "Production efficiencies and accurate stock planning enabled manufacturing costs to be controlled in line with sales volume and helped cushion the impact of ingredient cost increases."
The directors signalled the hot summer weather of 2013 had resulted in improved ice cream sales in the current trading year but warned retailers were still reluctant to accept price increases.
