01 · The model

It reads the valley, then writes you one sentence.

No dashboards, no indices out of 100. Published epidemiology runs quietly against your parcels — and speaks only when something needs doing.

/01

Weather at canopy height

Not the airport forecast — temperature, rain and humidity where your vines actually live, parcel by parcel.

/02

Leaf wetness & infection

Hours of wet leaf, spore pressure, growth stage — the variables a good agronomist keeps in their head.

/03

Published science, not thresholds

Peer-reviewed disease models for mildew, oidium, botrytis and frost — quiet on purpose most days.

/04

A sentence with a deadline

"Treat before Thursday 18:00." When it speaks, it means it — and it tells you why.

02 · The record

The logbook a regulator accepts.

On 1 January 2027, EU rules make electronic spray records mandatory. Yours are machine-readable today — logged in the field in twenty seconds, exported in one tap.

03 · Two kinds of day

Most days, it tells you to relax.

You check five forecasts and act when three agree. SOSVine replaces the ritual: an explicit all-clear on quiet days, a deadline when the window is real.

▲ HIGH RISK · DOWNY MILDEW

Treatment window closes Thursday 18:00

Two dry days left. After Thursday, rain keeps the tractor out of São João for a week — and infection pressure keeps climbing.

04 · The winter half

Other apps sleep from October to March. Vineyards don't.

Half the year happens when every competitor goes quiet. SOSVine works in January.

PRUNING WINDOWS

Safe to prune until Saturday

Wound-infection risk from rain, tracked per parcel — so esca doesn't enter through a cut made on the wrong day.

FROST NIGHTS

−1.5 °C at canopy height, 04:00

Cold air pools row by row. The warning arrives the evening before — not in the morning post-mortem.

CHILL ACCUMULATION

Budbreak, forecast in winter

Chill hours accumulate all season — so spring's first decisions are planned, not improvised.

05 · Everything else

One app for the whole year.

Ten disease models, all weather free, the legal record, the community — and the winter half of the year.

06 · The science

Named models, checkable claims.

Every alert traces back to a published model and a dated infection event — so you, or your agronomist, can check the science.

Read the methodology →
/01 Infection events from published kernels — never a score out of 100
/02 Growth stage from degree-days on the BBCH scale
/03 Frost severity from FAO critical-temperature tables
/04 Winter chill in Dynamic Model chill portions

−50%

fungicide use versus calendar spraying, with no added disease risk — peer-reviewed, cited in the app.

2.45 ha

the size of vineyard we build for. Real growers with scattered parcels — not estates with agronomy departments.

6 languages

and both hemispheres. Working in some 60 wine countries — every alert in the grower's own language and time zone.

07 · Price, published

€49.99 /year

Priced for two hectares, not two hundred. The spray record is free.
