What it’s worth

One good water call can protect a season’s margin.

What protecting a little yield is worth.

Grapes cost about R75 800 per hectare to grow, and the margin is thin: roughly R11 000 per hectare. Protecting a little yield on your best blocks in a hard week moves that margin. Try your own numbers.

water you’ll have to take from some blocks. Rigo shows which.

Example only, from your inputs and published averages (Vinpro Cost Guide 2025/26; 5 000 m³/ha planning figure). Not a promise and not a result. In the pilot we measure the real number on your blocks.

How we’ll prove it: with the vine, the meter and the Eskom bill, not opinions.

  • The vine

    Stem readings stay inside the target band your consultant set.

  • The water meter

    Water per block against last season, adjusted for a hotter summer.

  • The Eskom bill

    More of your pumping lands in off-peak hours.

  • The record

    Actions done before the window closed. Every time-stamp kept.

  • Your consultant

    Ranks the same days blind. We check that Rigo agrees.

  • Your money

    We only continue if it’s worth paying for. You decide.

The 2026/27 pilot

One farm. One summer. Measured.

We’re choosing one irrigated wine farm for the 2026/27 pilot: 4–8 blocks, Dec to Mar, no new hardware to start. You decide if it’s worth paying for.
