The influence of typical feeds in the five mountain regions Engadin, Rheinwald, Emmental, Luzerner Hinterland and Toggenburg on the fatty acid (FA) compostion of milkfat was investigated over one year from May 2004 till April 2005. The average altitude of grass-based feed (GBF) growth was 1247 ± 465 m for the summer feed and 1136 ± 310 m for winter feed. Compared to winter, summer milk had a significantly lower concentration of saturated FA (SFA) (-8.6 %) and significantly higher contents of mono-unsaturated FA (MUFA) (+19.9 %), poly-unsaturated FA (PUFA) (+21.7 %), conjugated linoleic acid (CLA) (+70.1 %), and trans FA without CLA (+56.7 %). Summer and winter milk from mountains did not significantly differ with respect to the contents of n-3 and n-6 FA. However, the content of the main n-3 FA (α-linolenic acid) was significantly higher in summer milk and its content was positively correlated with increasing percentages of GBF and altitude. According to Swiss food law regulations, the commercialisation of the nutrional advantages of mountain milk is not possible at the moment.
At the new Centre of Excellence for Raw-Milk Products, Agroscope and Grangeneuve interviewed test subjects about the popularity of Vacherin Fribourgeois PDO cheeses made from raw and thermised milk. The study showed that the market potential of raw-milk cheeses has not yet been exhausted.
Divico, Agroscope’s new disease-resistant grape variety, is noted for the quality of its wines. Blending trials with the Pinot Noir variety have shown that Divico is also highly suitable for correcting colour intensity in the latter.

As part of the trend towards vegetarian and vegan products, Agroscope looked into the production of plant-based alternatives to soft cheese based on Swiss raw materials.
