BoomCellar: Wine Stock Index

Wine stocks, tracked in one number. BoomCellar puts the BoomCellar WINE Index — a cap-weighted wine stock index of the world's listed wine companies — on your phone, with the companies behind it, their investor calendar and alerts when something moves. Editorial research and market data, not investment advice. WHO IT IS FOR Investors and professionals who follow wine equities: the wine producers, champagne houses and wine groups that trade on stock exchanges from Sydney and Santiago to Paris, Milan and London. If you invest in wine through the stock market rather than by the case, or cover wine shares for a living, BoomCellar keeps a sourced record of which listed wine companies exist and how their stocks move. WHAT'S INSIDE • Index — the WINE index level, day change and performance since its base (100 on 3 July 2026), in US dollars and euros, with the as-of session, weighting and constituent count as the feed states them. • Companies — every constituent with its index weight, exchange and country. Star a company to keep it at the top and see its last close. • Calendar — results dates, AGMs, dividends and trading updates, soonest first, plus the listing and IPO pipeline (open stages only, straight from filings) and the most recent events. Every row links to its source. • Monitor — the newest issue of the Wine Stocks Monthly Brief: title, date, composition at cut-off, and a link to read it on boomcellar.com. • Alerts — switch them on and the app tells you when the index moves by the published threshold in a session, when a company joins or leaves the index, when a calendar event falls within the week, and when a new Brief is out. THE WINE STOCKS IN THE INDEX Constituents today include Treasury Wine Estates and Australian Vintage (ASX), Viña Concha y Toro and Viña San Pedro Tarapacá (Santiago), Yantai Changyu Pioneer Wine (Shenzhen), the champagne houses Laurent-Perrier, Lanson-BCC and Maison Pommery & Associés plus AdVini (Paris), Italian Wine Brands and Masi Agricola (Milan), Schloss Wachenheim (XETRA), Bodegas Riojanas (Madrid), Purcari Wineries (Bucharest), Ambra (Warsaw), Sula Vineyards (NSE), Chapel Down and Naked Wines (London), Delegat Group and Foley Wines (NZX), and Crimson Wine Group and Willamette Valley Vineyards (US). Membership follows the published methodology and changes over time; the app always shows the current list. On boomcellar.com, BoomCellar also publishes the CRU boutique-winery index and the EAST Asia-Pacific index. BUILT FOR A PHONE, NOT COPIED FROM A WEBSITE • Alerts on index and IPO events, evaluated on your phone by comparing each fetch of boomcellar.com's feeds with the previous one; notifications are local. No push server, no device token, no account. • Watchlist on device. Your starred companies live in the app's own storage and nowhere else. • Offline last snapshot. Every feed's last fetch is kept on the device and shown with its own date when there is no connection. NO ACCOUNT, NO ADS, NO TRACKING No sign-up, no advertising, no analytics SDK and no in-app purchase. The app's only network requests are to boomcellar.com for its published data feeds. HONEST ABOUT ITS LIMITS Prices are typically 15–20 minutes delayed and market caps are approximate; constituent weights follow the published methodology, versioned and dated on boomcellar.com/methodology. Nothing in this app is a recommendation to buy or sell any security, and past index levels say nothing about future returns. Capital is at risk. The same index, calendar and Monthly Brief are on boomcellar.com. Built by JukkaBlomberg.com — one founder, an AI-native team, on Portfolio OS. More apps at jukkablomberg.com/apps.
