We opened the subjects of water needs of the vine, how they are related to yield and quality, and how to use available vineyard technology to supply those needs in the correct time - and save both the environmental cost of pumping and using unnecessary water, and the financial resources needed to do so,

In the first episode of Vine & River podcast, we interviewed Garrett Buckland, partner at Premiere Viticulture.
