Archive Site: Country Wines
Country Wines is located in the North Hills on Babcock Boulevard. They have both wine making supplies and beer brewing supplies.
I haven't been there myself. However, I've heard they have a large selection of supplies. They have several homebrewers on staff, including several who have won awards in national competitions. They also have a certified BJCP Certified beer judge on staff.
Their prices are reported to be somewhat higher than South Hills Brewing Supply.
