Dairies, bakeries and other food producers increased their prices by an average of 2.7 compared to September last year, the Federal Office of Statistics said.
Butter and milk showed the most striking price rises, increasing by 32.1 percent and 18.2 percent, while cheese and yogurt also cost 8.8 percent more over the 12 months.
Prices for dairy products have varied a lot in recent years, however, with prices in autumn 2007 and autumn 2011 having stood at a similar level to now.
Wine costs 7.5 percent more, while potatoes have gone up by 6.4 percent. Bread prices have also gone up 2.9 percent.
However, some key products have actually fallen in price, Focus reported. Coffee prices are down 2.5 percent, whilst meat, excluding poultry, is on average 2.4 percent cheaper.
August saw an average price rise of 3.7 percent, and in July it was 4.1 percent.
The "producer price" statistics measure the price of the goods as they leave the manufacturer, before they enter the market, so they can be used as an indicator of how consumer prices are likely to develop.
In contrast, the overall average "producer price" of goods, including metal, wood products and energy, fell by 0.5 percent compared to September last year.
