Predictions of grape yields are extremely important to juice processors and wineries but until recently, forecasting yields has relied on expensive and labor-intensive hand-sampling methods. However, a new approach, Trellis Tension Monitor has been developed that works by detecting weight change on trellised grapevines as the vine and grapes grow. Using 10 commercial vineyards, researchers found that TTM produced more-accurate estimates of yield than previous methods.
