What began as a single depot in Düsseldorf has grown into a network of around 350 depots across the DACH region, where customers are invited to come in, taste and enjoy. Its online shop, jacques.de, extends that promise into the digital channel — with an extensive range of wines, a winemaker directory and depot pages that thousands of visitors browse every day. The shop is built as an Angular single-page application on top of headless commerce and content APIs, a modern architecture that gives the team full freedom over the experience but also puts the rendering work on the visitor's device. That is exactly where speed becomes a commercial question: on image-rich listing and product pages, every extra second of waiting is friction on the path to purchase. To make browsing feel as effortless as a visit to a depot, Jacques' Wein-Depot introduced Speed Kit — with the goal of delivering pages dramatically faster without touching the existing stack.",[11,20,22],{"id":21},"challenge","Challenge",[16,24,25],{},"A single-page application shifts rendering to the client: before a visitor sees a product image or a price, the browser has to download and execute the application bundle and fetch content from the commerce and content APIs. For Jacques' Wein-Depot, this affected precisely the pages that matter commercially — the wine listing pages and the product detail pages where customers make their decision. The team wanted a substantial improvement in load times across these surfaces without rebuilding the frontend, changing the headless architecture, or adding development effort on their side.",[11,27,29],{"id":28},"solution","Solution",[16,31,32],{},"Speed Kit was added as a lightweight optimization layer on top of the existing shop — no architectural changes required. Because jacques.de is a single-page application, Speed Kit renders the pages in the background and serves visitors a ready-made view instead of an empty application shell, so content appears without waiting for the bundle and the API round trips. On top of that sits predictive preloading: Speed Kit anticipates which page a visitor is most likely to open next and quietly prepares it in advance. The result is a browsing experience that feels immediate — above all when moving between listing and product detail pages, the surfaces where speed drives dwell time and conversion.",[11,34,36],{"id":35},"results","Results",[38,39,41],"h3",{"id":40},"predictive-preloading-coverage","Predictive Preloading Coverage",[16,43,44],{},[45,46],"img",{"alt":47,"src":48},"Predictive preloading coverage on jacques.de: 100% of navigations, 93% preloaded, 61% prerendered","\u002Fimages\u002Fcustomers\u002Fjacques-wein-depot\u002F1.webp",[38,50,52],{"id":51},"performance-improvements-largest-contentful-paint-lcp","Performance Improvements — Largest Contentful Paint (LCP)",[16,54,55],{},"During the PoC phase, Speed Kit produced substantial LCP gains — most pronounced on the listing and product detail pages, the shop's central browsing and decision surfaces.",[16,57,58],{},[45,59],{"alt":60,"src":61},"Largest Contentful Paint before and after Speed Kit on jacques.de, by device and across the LCP rating distribution","\u002Fimages\u002Fcustomers\u002Fjacques-wein-depot\u002F2.webp",[38,63,65],{"id":64},"business-impact-poc-phase-conversion-rate-analysis","Business Impact — PoC Phase: Conversion Rate Analysis",[16,67,68],{},"Over the PoC phase, a Speed Kit-accelerated group was measured directly against an unaccelerated control group across more than 286,000 users and 446,000 sessions.",[70,71,72,80,86,92,98],"ul",{},[73,74,75,79],"li",{},[76,77,78],"strong",{},"Revenue:"," +4.04% (relative)",[73,81,82,85],{},[76,83,84],{},"User conversion rate:"," +2.22% (relative)",[73,87,88,91],{},[76,89,90],{},"Transactions \u002F orders:"," +2.12% (relative)",[73,93,94,97],{},[76,95,96],{},"Add-to-cart rate:"," +1.84% (relative)",[73,99,100,103],{},[76,101,102],{},"Average order value:"," +1.89% (relative)",[16,105,106],{},"Every commercial metric moved in the same direction, with the group split confirmed as balanced (no sample ratio mismatch).",[11,108,110],{"id":109},"conclusion","Conclusion",[16,112,113],{},"For Jacques' Wein-Depot, speed is what makes a large wine range enjoyable to browse.
