The Drinks Shelf Showdown: Coffee, Isotonic, and Milk Tea Picks

The drinks aisle is where a grocery shop stops being a chore and starts being a holiday. It’s the shelf for the 3pm slump, the post-football thirst, and the nostalgic craving for a milk tea that tastes like a Taipei night market. We’ve lined up three very different ways to quench that: a Vietnamese instant coffee that means business, a Malaysian isotonic that’s a national reflex, and a Taiwanese milk tea mix that’s pure comfort in a mug. Here’s what we’d actually reach for.

First impressions

This is a category for decision-makers: the coffee is for the person who needs a proper hit without the fuss, the isotonic is for the one who just finished a run (or a long shift), and the milk tea is for anyone who believes a drink can be a hug. Each one answers a different question, but they all share that satisfyingly straightforward appeal — no brewing equipment, no barista skills, just hot water or a cold fridge.

What it tastes like

Let’s start with the heavyweight. Trung Nguyen G7 Gold Instant Coffee Rumi is a Vietnamese classic, and the "Gold" label signals a step up from the standard red tin. The blend of soluble and microground coffee means you get a proper crema-like texture and a deeper, earthier body than your average instant. The non-dairy creamer and sugar are already in the mix, so it lands sweet and smooth with a gentle bitterness at the back — think of it as a café-style cup that’s ready in thirty seconds. It’s robust, but the microgrounds give it a slightly gritty, authentic edge that fans of Vietnamese phin coffee will recognise.

Next, the 100 Plus Isotonic Drink — a Malaysian institution that’s basically the country’s answer to Lucozade. It’s a carbonated, lightly sweet isotonic with a clean, citrusy fizz that’s far less syrupy than you might expect. The minerals (sodium, potassium, calcium) do the heavy lifting for hydration, but the taste is refreshingly neutral — think lemon-lime soda that’s been dialled back to something you could drink on a hot day without feeling sticky. It’s crisp, cold, and exactly what you want after sweating.

Finally, the 3:15 PM Sun Moon Lake Milk Tea from Shih Chen. This one is a treat: a Taiwanese instant milk tea that uses both black and oolong tea leaves for a more complex, slightly toasty flavour than the usual brown-sugar bombs. The creamer makes it rich and velvety, and the sweetness is prominent but not cloying — it’s like a proper bubble-tea-shop base without the tapioca. Our honest favourite? The milk tea. It’s the one we’d buy again just for the comfort factor.

Before you buy

The G7 Gold is for the coffee purist who wants a strong, sweet Vietnamese-style cup without leaving the house — just check the milk and soya line if you have allergies. The 100 Plus is the one for the athlete, the hungover, or anyone who needs a quick electrolyte top-up; it’s allergen-free as far as the supplier states, but the preservative list is worth a glance. The 3:15 PM milk tea is for the sweet-toothed nostalgic who wants a proper tea-shop moment at home — but it’s strictly for those who can handle dairy. Serve the milk tea hot with a side of buttery biscuits, or pour it over ice for a summer treat.
