Ideal for bottling larger volumes, this filler allows the individual home wine maker or small winery to efficiently fill wine bottles at an increased rate. Perfect for bottling 50 to 500 gallons. Efficient gravity-feed reservoir system allows you to consistently fill each bottle to the same exact level. Just start the flow of your wine through the back entry shut-off valve, put a bottle over the filling rod, and push down to start the flow. You'll be done before you know it.
