Harvest Planning and Logistics for Vineyard Managers
A practical guide to harvest planning covering Brix targets, picking crew management, bin tracking, winery communication, and the records needed to execute a smooth harvest.
Starting Harvest Planning Early
Harvest planning that starts at veraison is too late. The blocks you'll be picking in September and October need to be in your planning framework by late July at the latest. That means reviewing your block list, understanding the ripening trajectory from current Brix and acid readings, confirming your picking crew availability, and aligning with your winery buyer on intake capacity and scheduling windows.
The compressed nature of harvest, where multiple blocks may hit Brix targets within days of each other, means that every logistics element needs to be confirmed before the season peak rather than figured out on the fly. Running out of bins on a Monday morning when three blocks are ready is a situation that damages your crop, your relationship with your crew, and your winery relationship all at once.
Brix Targets by Variety and Buyer
Brix targets are set in coordination with your winery buyer and reflect the style of wine being produced. A sparkling base wine producer may want Chardonnay at 19 to 20 Brix with 9+ g/L titratable acidity. A premium still Chardonnay program may want 23 to 24 Brix. A high-volume commercial program may have different targets entirely.
Track your Brix sampling data by block throughout the ripening period. Record sample date, block, sample size (number of berries, from how many vines, which locations in the block), Brix reading, pH, and TA if you're testing those parameters. Plot these readings over time and compare the trajectory to prior years. A year where Brix is accumulating two weeks ahead of your historical average means you need your crews, your winery communication, and your bins ready correspondingly earlier.
Sampling Protocols
A reliable Brix sample represents the actual sugar level in your fruit. A misleading sample produces bad decisions. Standard protocol is to sample 100 to 200 berries per block, collected from multiple locations across the block (front, middle, back rows), from multiple heights in the canopy, and from multiple positions on the cluster (tip vs. shoulder). Put berries in a bag, crush, and read the juice with a refractometer.
The more variable the block, the larger the sample you need. A block with noticeably uneven ripening, such as lower ground that's consistently behind the upper portions, should either be sampled as two separate zones or sampled with a larger total berry count to average across the variability.
Picking Crew Management
Labor availability during harvest is one of the most constrained resources in wine grape production. Your crew relationships, built across prior seasons, are part of your vineyard infrastructure just as much as your trellis system. Communicate your anticipated harvest windows to crew supervisors in July and confirm again when Brix trajectories clarify in August.
Record planned and actual crew start times, block assignments, crew size, tons picked per block per day, and any issues that affected picking speed or quality. This data helps you plan future harvests more accurately and gives you documentation if labor rate questions arise. Per-block picking records also feed into your cost of production calculations for the season.
Bin Tracking
Bins are an expensive, finite resource that disappear into logistics chaos during peak harvest. Track every bin by block, pickup date, winery delivery, and return date. At minimum, record how many bins went out to each block on each picking day and confirm they came back or went to the winery. If you're selling to multiple wineries, keeping bins separated by buyer matters for both logistical and contractual reasons.
Electronic bin tracking with numbered bins and a simple spreadsheet or VitisScribe log by block eliminates most bin reconciliation problems. The alternative, which is trying to remember after the fact where 80 bins went during a chaotic three-week harvest, produces errors that affect your payment records and your ability to account for fruit movement.
Winery Communication
Your winery buyer needs advance notice to schedule receiving, refrigerated storage, and processing equipment. Most wineries want 48 to 72 hours notice for a commercial pick, and premium programs may want a week's notice and multiple Brix checks before confirming the pick date.
Document every communication with your winery contacts about harvest timing in your records. This includes text messages, emails, and phone calls where specific Brix numbers or pick dates were discussed. In the event of a dispute about fruit condition, pick timing, or contract performance, your communication record is the contemporaneous evidence of what was agreed.
PHI Clearance Before Harvest
Before any block goes to picking crew, verify that all pesticide PHIs are cleared. Pull up the spray history for the block and check every product applied in the past 60 days against its labeled PHI. This is a harvest checkpoint that should happen as a formal step in your planning process, not an afterthought.
VitisScribe's harvest clearance report pulls all spray records for a block and shows PHI clearance status automatically, making this review a two-minute task rather than a manual calculation across a season's worth of paper records. Any block with a pending PHI issue should be flagged before crews are scheduled.
