There are no moles in Saaremaa and Hiiumaa. When hay is cut to make silo on the continent, harvester blades cut close to the ground and because of the presence of mole hills, a little soil inevitably gets mixed in with silo. This includes good and bad bacteria in the soil.
In Saaremaa, however, no soil is mixed in with soil, so milk has a purer taste (because animal feed is cleaner).
Saaremaa is the Sun Capital of Estonia. According to Statistics Estonia, the sunniest area in Estonia is on Sõrve Peninsula in Saaremaa, where sunshine can be enjoyed for 2,101–2,200 hours per year. The northern area of Puhtu-Laelatu Nature Reserve in Lääneranna Parish is the most species-rich wooded meadow in the world. The abundance of species in the nature of the islands and the western coast gives milk its special flavour. Because small producers graze their cows on natural grasslands more frequently, their milk has more of that special flavour. In cheese production, the limestone base in Saaremaa adds to the characteristic by making cheese milk rich in calcium and promoting milk coagulation.
