Adjacent vineyard — the big context

3545 Bloomfield Rd — 5 Wells Vineyard (Wells / Kwon family, immediate NE neighbor):

OwnersWells Crawford Maclain & Jane Selina Kwon
Operating entity5 Wells Family Vineyards LLC (formed 2015)
Acreage72 ac
Vineyard32 ac planted Pinot Noir / Chardonnay
Residence3,759 sf 2008-built modern estate home
Current listing$6,500,000 — active, listed 2025-12-18, 143+ DOM as of May 2026
Previously circulated$10,500,000 (Crexi / Cru Land — likely earlier listing or off-market ask)
Price cut~38% reduction
MLS #325103677
Listing agentDavid Carciere, Cru Land Company / Engel & Völkers St. Helena
Websitehttps://www.5wellsvineyardestate.com/

Why this matters for 3845:

  1. The adjacency confirms the soils-and-microclimate of this stretch support premium Pinot Noir / Chardonnay (the Sebastopol Hills sub-AVA).
  2. The 38% price reduction signals softening high-end vineyard demand into 2026 — Sebastopol’s $200K+/ac premium is being tested.
  3. If 5 Wells trades closer to $5M than $6.5M, the implied per-ac comp drops to ~$70K/ac. That sets a ceiling on what a vineyard-development premium can layer onto raw land at 3845.
  4. Wells / Kwon listing implies the family is exiting — which could be tactically relevant for a buyer trying to assemble multiple Bloomfield Rd parcels.

$/acre tier summary (west Sebastopol / Sebastopol Hills, 2023–2026)

  • Raw vacant ag land, 50–100 ac, no significant home: $25K–$50K/acre (Green Valley benchmark)
  • Plantable but unplanted land in vineyard-suitable belt: $50K–$80K/acre (vineyard upside premium)
  • Land with developed vineyard + estate home: $90K–$160K/acre (5 Wells, Cherry Ridge)
  • Estate residences on small lots: $110K–$1.2M/acre (Furlong, 2836 Bloomfield)

Working valuation

TrackAssumptionMathRange
A — Raw ag land$35–50K/ac × 51.15 ac—$1.78M–$2.56M
B — Vineyard-development potential$50–80K/ac × 51.15 ac—$2.56M–$4.09M

Net adjustments:

  • (−) LEA B6 160: no new primary dwelling permitted on sub-160-ac parcel; 1925 legal nonconforming dwelling may be maintained/replaced. Dominant value cap.
  • (−) 5 Wells 38% list-price cut → softening high-end segment.
  • (−) Engineered moto track is amenity for MX buyer, $150K–$400K remediation for non-MX.
  • (+) Adjacent to a known vineyard (validates soils for Pinot).
  • (+) Twin Hills/West Sonoma school district premium.
  • (+) Scarcity of mid-size Bloomfield Rd parcels.

Off-market as-is range: $2.0M–$3.2M Most likely clearing price: ~$2.4M–$2.8M ($47K–$55K/ac)
