Woman who stole 19 bottles of wine caught by Sheng Siong’s facial recognition system

How Did Sheng Siong's Facial Recognition System Catch a Serial Wine Thief?

Sheng Siong's facial recognition system flagged Catherine Tan Li Eng after she stole 19 bottles of wine across seven separate visits — and honestly, this story says as much about Singapore's supermarket wine culture as it does about retail surveillance tech. If you've ever browsed the wine aisle at your local Sheng Siong and wondered who's buying all those mid-range bottles, well, now you know at least one person wasn't buying them at all. The case is a surprisingly revealing window into how seriously Singaporeans take their supermarket wine runs — and how seriously supermarkets are now taking security.

Catherine Tan Li Eng is the 47-year-old woman at the centre of the case, sentenced to eight days in jail after pleading guilty to the thefts. She made off with 19 bottles of wine from Sheng Siong over seven occasions before the supermarket's facial recognition system identified her and flagged the pattern. The sheer repetition of it — seven visits, same store, same category of product — is what makes this story stick. It wasn't opportunistic. It was a routine.

What Is Sheng Siong's Facial Recognition System and How Does It Work?

Sheng Siong is a homegrown Singaporean supermarket chain with over 60 outlets across the island, known for competitive pricing on everyday groceries — including a surprisingly well-stocked wine and spirits section that rivals some bottle shops. The chain has quietly invested in facial recognition technology as part of its loss-prevention infrastructure, a move that puts it ahead of many regional supermarket operators. Facial recognition systems in retail work by capturing images of shoppers at entry points, cross-referencing them against a database of known offenders or flagged individuals, and alerting security staff when a match is detected.

According to retail security industry data, supermarkets in Singapore lose an estimated 1–2% of annual revenue to shoplifting and internal theft — a figure that sounds small until you apply it to a chain the size of Sheng Siong. The technology isn't new globally, but its deployment in a mainstream Singaporean supermarket context is a signal of where things are heading. If you thought your weekend wine run was anonymous, think again.

Why Should Singapore Wine Lovers Actually Care About This Story?

This isn't just a crime story — it's a lifestyle story. Sheng Siong has become a genuinely credible destination for affordable wine in Singapore, stocking everything from Chilean Sauvignon Blancs under $15 to French Bordeaux blends that wouldn't embarrass you at a dinner party. The fact that someone thought these bottles were worth the risk of repeated theft tells you everything about how the supermarket wine segment has levelled up in Singapore. We're not talking about cooking wine here.

For the average HotInSG reader who picks up a bottle or two before a weekend gathering, the takeaway is twofold. First, Sheng Siong's wine selection is genuinely worth exploring — the value-to-quality ratio on many of their labels is hard to beat. Second, the store is watching. Not in a paranoid way, but in a very 2024 way. Facial recognition is now part of the shopping experience whether you're aware of it or not.

19 bottles across 7 visits — Catherine Tan's wine-stealing streak lasted long enough to suggest Sheng Siong's selection is genuinely compelling. The facial recognition system, however, was more compelling still.

What Should You Actually Buy at Sheng Siong's Wine Aisle?

Since we're here and talking about Sheng Siong wine, let's make this useful. The supermarket's wine section punches well above its weight for a grocery store, and if you know what to look for, you can walk out with a genuinely solid bottle without spending more than $25. Here are five picks worth grabbing on your next run:

• Jacob's Creek Double Barrel Shiraz (~$18): Smooth, approachable, and reliable for casual entertaining.
• Frontera Cabernet Sauvignon (~$12): Chile's workhorse red — great for cooking or a weeknight pour.
• Yellow Tail Pinot Grigio (~$14): Crisp and easy, ideal for Singapore's humidity.
• Casillero del Diablo Reserva Sauvignon Blanc (~$16): Bright citrus notes, pairs well with hawker seafood.
• Wolf Blass Red Label Shiraz Cabernet (~$15): An Australian classic that consistently overdelivers at this price point.

None of these will win awards, but all of them will make your Friday night considerably better without breaking $25. That's the Sheng Siong wine proposition in a nutshell — and apparently, it's compelling enough that at least one person decided the normal rules didn't apply to her.

Is Sheng Siong Worth Visiting for Wine and Groceries?

Yes — Sheng Siong is absolutely worth visiting for wine and everyday groceries, especially if you're after value without sacrificing quality.

For anyone planning a dinner party, a picnic at Gardens by the Bay, or just a quiet night in, Sheng Siong is one of Singapore's most underrated wine stops.

The Catherine Tan case is a reminder that the store takes its inventory seriously — seriously enough to deploy facial recognition technology that caught a repeat offender across seven visits. That level of investment in loss prevention signals a retailer that knows its wine section is a meaningful revenue driver.
