Hidden behind fabric curtains in Tiong Bahru, Dirty Sips is quietly rewriting Singapore's cocktail scene. Tucked inside Dirty Supper, this intimate 30-seat bar has built a cult following not through Instagram gloss, but through craft that actually shows up in the glass. In a city where rooftop bars compete on views and garnishes compete on theatre, Dirty Sips competes on something rarer: substance.
Zero-Waste Cocktails, Maximum Flavour
The zero-waste philosophy here is not a marketing line. Every ingredient that comes in goes out in a glass. Citrus peels are candied or pressed into oils. Spent botanicals become infusion bases. The team sources locally where possible and rotates the menu based on what is available and what can be used in full. The result is a tightly curated list of 10 to 12 cocktails that changes seasonally.
Signature serves have included a clarified milk punch aged in-house, a fermented pineapple Negroni, and a smoked tamarind sour that takes three days to prepare. The complexity sits in the process, not the presentation.
Why Tiong Bahru Works
Tiong Bahru's mix of heritage shophouses, independent cafes, and low-key creative energy is the right backdrop for a bar that does not shout. Dirty Sips draws locals, regulars, and in-the-know visitors — the crowd that appreciates what it is doing rather than how it photographs.
The 30-seat format keeps service personal. Bartenders know their regulars, explain the menu without being precious, and take custom orders when ingredients allow. It is the kind of place where you sit at the bar, not at a table.
Sustainability That Shows Up Operationally
Singapore produces roughly 744,000 tonnes of food waste annually according to the National Environment Agency. The bar industry contributes a disproportionate share through citrus offcuts, over-ordered spirits, and single-use garnishes. Dirty Sips is one of a small number of Singapore bars taking this seriously at an operational level rather than just as brand messaging.
Herbs come from urban farms. Spirits are chosen partly on packaging — bulk where possible, recyclable where not. The intent is visible in every menu decision.
What to Order and When to Go
The menu rotates but some principles hold: the sours are uniformly excellent; ask about the milk punch if it is on; let the bartender read the mood. Cocktails are priced between S2 and S8 — fair for the level of preparation involved.
Dirty Sips is open Wednesday to Sunday from 6pm. No reservations. First come, 30 seats. It fills up by 8pm on weekends.
