Cascade Analytical has established a special database for wine grapes and concords. We test the grape leaf tissues at full bloom and at verasion. Grape tissue analysis gives valuable information and can help to diagnose deficiencies before there is a problem. With your help, we can continue to build a solid set of nutritional data which will have optimal nutrient ranges and are fined tuned to reflect the unique growing conditions of the Pacific Northwest. We have already done this for the tree fruit industry and adaptation to wine grapes is easily made.
At Cascade Analytical, we pride ourselves in assisting growers and wine makers to excel at their crafts.
