What Vine-Level Records Look Like at Scale: Lessons from a 184,000-Vine Estate
Most vineyard record-keeping systems track blocks. Some track rows. Almost none track individual vines.
The reason is straightforward: tracking 184,000 individual data points across three vineyards, 57 blocks, and 35 years of planting history sounds like a data management nightmare. And with spreadsheets or paper maps, it would be.
But with RTK GPS and a purpose-built platform, vine-level records stop being a burden and start being the foundation everything else rests on. This is what that looks like in practice.
The Estate
The property in question is a premier Napa Valley estate producing Bordeaux blends from three vineyards spanning nearly 200 acres. Plantings date back to 1990. The varietal mix is 75% Cabernet Sauvignon, 14% Cabernet Franc, 6% Petit Verdot, and 4% Merlot, planted across six rootstock combinations.
This is not a research vineyard or a technology showcase. It is a working estate where the vineyard team needs to make decisions every day about which vines to pull, where to replant, which blocks to prioritize for crew work, and how to plan three to five years ahead.
What "Vine-Level Records" Actually Means
Every vine in the operation carries a digital record with:
- GPS coordinates at sub-centimeter accuracy (RTK-corrected)
- Variety and rootstock pairing
- Planting year (ranging from 1990 to 2025)
- Production status (Producing, Non-Producing, Miss, or Rootstock)
- Health history (disease observations, treatments, roguing decisions)
This is what we call "digital flagging tape." Just like physical flagging tape marks a vine in the field, a digital record marks it permanently in the system -- except the digital version never fades, never falls off, and is searchable from anywhere.
The numbers behind this deployment:
| Metric | Value | |---|---| | Vines individually recorded | 183,996 | | Blocks managed | 57 | | Vineyards | 3 | | Varieties tracked | 4 | | Rootstock combinations | 6 | | Years of planting history | 35 | | Team logins (cumulative) | 978 | | Saved queries | 74 |
Those last two numbers matter. 978 team logins and 74 saved queries mean this is not shelfware. The vineyard team uses this system daily because the data is trustworthy enough to act on.
Four Problems This Solves
1. Replant Planning Without Guesswork
The estate currently has a 5.2% miss rate -- 9,534 vines that need replacement. Another 9,326 are rootstock plantings in various stages of development.
Without vine-level records, replant planning looks like this: walk the blocks, count gaps, estimate from memory, order rootstock, hope the numbers are close enough.
With vine-level records, the team can filter to every missing vine in Block 12A, see exactly which rootstock was used in the surrounding vines, check the planting year of the originals, and generate a replant order that accounts for variety, rootstock, and spacing. No walking. No counting. No estimation.
When you are spending $15-25 per vine on replants, getting the count wrong by even 5% across a 184,000-vine operation means wasting tens of thousands of dollars.
2. Disease Tracking That Persists Through Crew Changes
Red Blotch and Leafroll do not respect management transitions. A vine flagged for Red Blotch in 2019 needs to be tracked through every subsequent season, regardless of which crew member walks that row, which viticulturist manages that block, or whether the vineyard manager changes entirely.
In a spreadsheet, disease history lives in a tab that nobody updates consistently. On paper maps, it lives in a filing cabinet that nobody opens. In a GPS-verified vine record, it lives permanently on that vine's digital profile -- visible to anyone with access, from anywhere.
This is institutional knowledge that does not depend on any single person's memory.
3. Regional Block Management Across Properties
Managing 57 blocks across three vineyards means the team needs to compare performance, allocate crew resources, and plan work orders across geography. A block at one vineyard might share the same variety-rootstock combination as a block five miles away, but perform completely differently.
Vine-level records make these comparisons possible without anyone manually assembling data from three different spreadsheets. The team builds saved queries -- 74 of them, in this case -- that surface exactly the information they need for recurring decisions.
4. Crew Collaboration at Scale
978 cumulative logins across the team means this is not a single-user tool. Multiple team members access the same vine records, add observations, update statuses, and coordinate work without the information bottleneck of everything flowing through one person's inbox or whiteboard.
For an estate operation where the vineyard manager, viticulturist, crew supervisors, and winemaking team all need different views of the same vineyard, shared access to ground-truth data eliminates the game of telephone that usually connects these roles.
Why GPS Ground Truth Matters
There are multiple approaches to vineyard data collection. Drones and aerial imagery provide canopy-level views. ATV-mounted cameras use computer vision to scan rows. Satellite imagery offers broad coverage at lower resolution.
Each has a place. But for permanent vine-level records -- the kind you build once and reference for decades -- the data has to be verified at the source. An AI model can predict that a vine looks unhealthy from a camera image. A crew member with an RTK GPS receiver can confirm that vine V-4782 in Row 23 of Block 7A has Red Blotch, tag it in the system, and that observation becomes a permanent, coordinates-verified record.
The difference matters when you are making roguing decisions, planning replants, or defending compliance records. Predictions are useful for scouting. Verified observations are necessary for records.
The Transition from Spreadsheets
Estates that move to vine-level records typically follow the same path:
-
Initial mapping: Walk the vineyard with an RTK GPS receiver. Each vine gets a GPS coordinate and basic attributes (variety, rootstock, planting year, status). For a 200-acre estate, this takes a few weeks of field work spread across normal operations.
-
Daily use: Once the base map exists, the crew adds observations during their normal walks. Disease flags, replant tracking, and status updates happen in real time on mobile devices.
-
Query building: As data accumulates, the team starts building saved queries for recurring questions. "Show me all Cab Sauv on 101-14 rootstock planted before 2000" or "Which blocks have more than 10% miss rate?"
-
Institutional asset: After one to two seasons, the vine records become the authoritative source of truth for the estate. New team members onboard by looking at the data, not by asking whoever has been there longest.
The hardware investment is modest: an Emlid Reach RX receiver (approximately $3,000) and mobile devices the crew already carries. The software subscription runs $25-120 per acre annually, depending on estate size.
What This Means for Your Estate
If your vineyard operation relies on spreadsheets, paper maps, or one person's memory for vine-level decisions, the question is not whether to digitize those records. It is when.
Estates that have made the transition consistently report the same outcome: the data they thought they had was incomplete, and the data they needed was easier to collect than they expected.
The estate profiled here started with a mapping phase, moved to daily use within one season, and now manages 184,000 vines across three vineyards from a single platform. Their team logs in daily. Their records span 35 years. Their replant planning is precise to the individual vine.
That is what vine-level records look like at scale.
