Vineyard Yield Estimator
Enter row spacing, vine spacing, clusters per vine, and cluster weight to estimate grape yield in tons per acre, kg per hectare, and wine cases per acre.
Vineyard Parameters
Distance between vine rows. Common range: 8–12 ft (2.4–3.7 m).
Distance between vines within a row. Common range: 4–8 ft (1.2–2.4 m).
Count clusters on 10–20 representative vines and average. Typical range: 15–60 clusters/vine.
Weigh 10–20 clusters near harvest and average. Common range: 80–200 g for wine varieties.
Enter total vines in the block to get whole-block estimated yield.
Enter vineyard parameters, then click Estimate Yield.

Summary
Enter row spacing, vine spacing, clusters per vine, and cluster weight to estimate grape yield in tons per acre, kg per hectare, and wine cases per acre.
How it works
- Enter row spacing in feet — the distance between vine rows (typically 8–12 ft).
- Enter vine spacing in feet — the distance between vines within each row (typically 4–8 ft).
- Enter the average number of clusters per vine counted across a representative sample.
- Enter the average cluster weight in grams — weigh 10–20 clusters and average them.
- Optionally enter total vine count to get a whole-block yield estimate in addition to per-acre figures.
- Click Estimate Yield to see tons per acre, kg per hectare, and estimated cases per acre.
Use cases
- Pre-harvest crop load forecasting to schedule picking crews and equipment.
- Estimating wine production volume to plan barrel, tank, and label inventory.
- Comparing yield potential across blocks with different trellis or spacing configurations.
- Calibrating vine crop load after cluster thinning to check against target tons per acre.
- Documenting block-by-block yield components for farm records and bonded winery reports.
- Teaching viticulture students the standard yield component calculation method.
