South Mountain Creamery has expanded their delivery area and covers much of Fairfax County. You can email them through http://smc.deliverybizpro.com/home.php and they will tell you whether your address is covered in their delivery area. Their dairy products are excellent, and for home cheesemakers their milk is not subject to high temperature pasteurization. I have gotten excellent ricotta yields from their whole milk, and their cream makes excellent butter. They also deliver a wider range of products such as meat or eggs from their farm as well as other local farms. Their pricing is competitive with supermarkets even with the delivery charge. Reliable, good, and local.
