QR Codes for Bottles & Cans

A label on a bottle or can is a close cousin of packaging generally, with its own wrinkle: the code is small, the surface curves, and the product can genuinely sit on a shelf — or in someone's fridge — for a long time after it was filled.

Drinks labels are where a QR code earns its keep the most: there's rarely room to print the full origin story, tasting notes, or sourcing detail directly on the label, so a scan is often the only practical way to tell that story at all. The question is the same one as everywhere else on this list — what happens to that code once the batch is bottled and out the door.

Why this is worth thinking about before printing

• Batches ship over a long window. A single print run of labels can cover months of bottling, and the product itself can sit on shelf for months more after that — a static code baked into thousands of labels is a long-term commitment to whatever it points to on day one.
• Tasting notes and vintages change. A code meant to point to detailed tasting notes for one batch is wrong the moment the next batch — with different notes — uses the same label design.
• Loyalty programs and promotions end. A code driving a rewards signup or a limited promotion is only useful while that program exists — after it wraps, the code either needs redirecting or it's dead weight on every can still in circulation.
• Sourcing and origin details are worth being able to correct. Supplier or ingredient sourcing can shift between batches; a static code can't reflect that without a relabel.

What a dynamic label code fixes

• Update what the code points to as the story behind the product changes — a new vintage's tasting notes, an updated sourcing page, a new loyalty program — without relabeling stock already bottled.
• Retire a promotion cleanly by redirecting the code to something else once it ends, instead of leaving old cans pointing at a dead page.
• See real scan data, which is one of the only ways to know whether people are actually engaging with the label beyond glancing at it on a shelf.

A few practical printing notes

Curved surfaces and small labels make bottles and cans one of the trickier print surfaces for a QR code to scan reliably on the first try:

• Avoid the curve where possible. A code that wraps around a can's curved body distorts more than one on a flat label panel — placing it on the flattest available area improves scan reliability noticeably.
• Contrast against foil and colour. Metallic cans, dark glass, and coloured labels all reduce reliable contrast — test the actual printed label under real lighting, not just a screen mockup, before a full run.
• Don't go too small. Labels are compact, but a code shrunk too far to fit becomes unreliable — decide early how much of the label the code genuinely needs rather than squeezing it in as an afterthought.
• Keep the quiet zone clear of texture. Embossed logos, foil borders, or busy label art crowding the code's edges are a common reason a label code fails to scan on the first attempt.
