Wine Stocks Monthly BriefSeptember 2026
A source-linked read of the month: what issuers reported, what was dated and had not yet happened, and what moved around the tracked registry.
Scope and cut-offScheduled, announced, reported and checked-and-absent are kept apart: an event with a date in a calendar is not an outcome. Issuer figures are recorded in the currency and period the issuer uses and are not restated, converted or set against another company.This is a benchmark and a read. It is not investment advice, it rates nothing and it forecasts nothing.
The source cut is dated 2026-09-22. It carries 22 qualifying constituents across 13 countries and 16 exchanges, with a further 30 names tracked but not admitted to a series. Those are separate denominators and are not added together.
3 series are computed from that registry. All are cap-weighted, all are denominated in euro, and all are based to 100 on 2026-07-03. WINE takes every qualifying row, which is 22 names in this cut; EAST takes the Asia-Pacific rows, which is 6. CRU's membership is a function of current accepted prices and FX rather than of the registry alone, so it is not stated at a cut-off and no count for it is printed here.
No index level, movement or return appears in this issue. A share-input question on one constituent is still open in the registry, and the public series could not be independently re-fetched in this pass, so a level computed here would not be reproducible from the same snapshot. It is left out rather than estimated.
What follows is a benchmark and a read. It does not rate or rank any listed company against another, it is not investment advice, and it makes no forecast. Where an event was dated but had not happened at the cut-off, the row says so and stays empty.

Results
| Issuer | Period | Standing | What the record says, and where it is |
|---|---|---|---|
| Maison Pommery & Associés POMRY.PA | H1 ended 30 June 2026 | Reported by the issuer | Revenue of €96.2m for the six months, against €109.3m in the prior reported period. The issuer's own comparable-growth figure is measured on a different scope — it excludes Heidsieck and interprofessional sales — so the two are not the same measure and are not netted together here.
|
| Lanson-BCC ALLAN.PA | H1 ended 30 June 2026 | Reported by the issuer | Revenue of €99.1m, with the issuer stating growth of 7.7 per cent year on year. First Heidsieck shipments and half-year seasonality both sit inside that figure. It is recorded as the issuer states it and is not set against another house, because the scopes differ.
|
| Ambra AMB.WA | FY2025/26 | Filed, read via a relay | Sales net of excise and trade charges of PLN 901.330m, against PLN 894.895m in the prior financial year. Read from a filing relay rather than from the issuer's own site, and both the fiscal period and the reporting currency differ from the euro reporters above.
|
| Italian Wine Brands IWB.MI | H1 2026 | Checked and not present | Board approval of the half-year result is dated 22 September in the issuer's own corporate-events calendar. At 13:43 EEST on 22 September the issuer's financial-documents page and press-release page carried no H1 2026 outcome. This row records a checked, bounded absence at that moment — not a statement about the whole day — and stays empty until a release exists.
|
| Schloss Wachenheim SWA.DE | FY2025/26 | Scheduled, not yet published | The annual report is dated 25 September in the issuer's financial calendar. On 22 September the issuer's reports page still ended with the prior year's annual report. The preliminary announcement published on 2 September is a separate document and is not read in its place.

Around the registry
| Issuer | Period | Standing | What the record says, and where it is |
|---|---|---|---|
| Viva Wine Group VIVA.ST · tracked in coverage | Offer by Riesling Ventures | Announced, not yet observed | The offeror reports 89,412,188 shares held or controlled, approximately 99.8 per cent of capital and votes, and states that compulsory redemption has begun. The 22 September last trading day is announced rather than observed at this cut-off, and the recorded stage is checked again on or after 23 September. This name is carried in coverage rather than in the tracked registry, so no series level moves on account of it.
|
| Delegat Group DGL.NZ | FY2026 final dividend | Scheduled, not yet published | A final dividend of NZD 0.22 per share is timetabled with an ex-date of 24 September, a record date of 25 September and payment on 9 October. Nothing in that timetable had occurred at the cut-off and none of it is stated here as an outcome.

CorrectionsA later result is added here as a dated note. A figure that has been published is never silently overwritten, and a correction keeps the original reading beside the new one.
