This crimson clover cover crop (see image above) provides a natural source of nitrogen for Grace Farm's vines. The pink nodules on the clover's roots (see image below) contain a haemoglobin-like protein. So, just as our blood carries oxygen throughout our bodies, these nodules transport life-giving nitrogen from the atmosphere into the soil. It's just another piece of the 'feed the soil' philosophy that contributes to the ability of our wines to express the amazing terroir of Grace Farm.
