I tried that viral “juice box ice cube” hack where you freeze a grape juice box, cut it open, and use it like instant highball ice. The idea is simple: the frozen juice should chill and flavour your whisky immediately. To test it properly, I set up two pours side-by-side—one lighter whisky at 46% ABV and one much stronger at 68% ABV—then poured about 1.5 oz (a full pourer) over the frozen juice “ice” and tasted right away with my cameraman. Here’s the honest result: it smells like grape, but it mostly tastes like whisky. On the 46% whisky, the grape flavour was barely there—more like a minimal mixed drink vibe that’s still quite pleasant. On the 68% whisky, the ice basically made no difference at the start; it was just very strong chilled whisky with only mild grape notes. After letting it sit around 15–20 minutes, things improved as more of the juice melted and the flavour finally came through, especially for the stronger whisky. So no, it’s not an “instant highball” like the way those videos film it. If you try this at home, don’t expect immediate results—give it time and you’ll enjoy it eventually.
