Liberation Bar Bangkok Review: The Speakeasy That Closed

Liberation Bar Bangkok was a hidden cocktail bar in Piman 49 on Sukhumvit Soi 49, where laboratory equipment helped turn herbs, apple peels, cacao, and even waterbugs into drinks worth remembering. We went for the speakeasy atmosphere we enjoy so much and came away equally impressed by what was in our glasses. Liberation is now listed as permanently closed. This Liberation Bar review looks back at its dark interior, inventive menu, and the four cocktails we tried, preserving a small piece of Bangkok’s cocktail history.

About Liberation Bar Bangkok

Liberation’s appeal came from its combination of a hidden setting and an experimental approach to cocktails. The bartenders used modern techniques to explore familiar ingredients in unfamiliar ways, producing drinks that gave us plenty to talk about. A rotary evaporator was central to that approach, helping the team work with aromas from plants, fruit, and less expected ingredients. The equipment was interesting in its own right; the real pleasure was tasting what the team did with it.

Liberation’s Closure

Liberation was included among the venues that had closed in BK Magazine’s December 2020 retrospective. Siam2nite also lists the bar as permanently closed. We retain this review for its photographs and first-hand account of the original drinks. The address identifies the former venue, and the old prices and hours should be read in that context.

The Science: Rotary Evaporation

A rotary evaporator, often called a rotovap, uses a vacuum to lower the temperature at which a liquid boils. As a flask rotates and is gently heated, vapor moves into a cooled condenser, turns back into liquid, and collects in a separate flask. In cocktail making, this can capture volatile aromas without the high heat of conventional distillation. The resulting distillate can be clear while retaining aromas from the original ingredients, as equipment manufacturer BÜCHI explains.

At Liberation, this gave the bartenders a broad collection of flavors to work with, including edible plants and a particularly fragrant waterbug. We liked the idea of this clear liquid “library”: an ingredient could arrive in the glass without looking anything like its original form. It made the menu intriguing, especially when the familiar flavor of a herb sat alongside something we had never expected to find in a cocktail.

The Atmosphere at Liberation

The interior was dark and minimalist, with black surfaces, wood, and a few reflective details. That restrained setting suited a bar where the drinks carried so much of the character. The large display of spirits drew our attention, and the high-tech equipment visible on the way to the bathroom gave us another reason to look around. An upbeat DJ performance brought energy to the room, completing the combination of a hidden bar and an evening out in Bangkok.

Liberation’s Original Drinks Menu

The menu we read had four parts, bringing together inventive cocktails and a substantial selection of spirits. Propaganda posters supplied the ideas behind several drinks, while the spirits covered gin, vodka, rum, mezcal, tequila, bourbon, and whiskies, including single malts, blends, and Asian labels. It was a menu that rewarded a little time: the cocktail names and ingredients made much more sense when read together.

Some combinations were immediately appealing; others invited questions. The staff were helpful when it came to navigating those unfamiliar ingredients, and their advice was useful in a bar with such an adventurous selection. Our drinks covered both ends of that spectrum, from a bright vegetable-and-basil cocktail to a waterbug distillation. The following tasting notes refer to that original menu.

The Four Cocktails We Tried

We tried Vegan War, Yellow Union Flag, Waterbug, and Cacao. Together, they showed the range of Liberation’s approach, from vegetable flavors and apple to an insect-derived aroma and Thai rum with chocolate. The ingredient lists were unusual, and we paid most attention to how those ingredients worked once the drinks reached us.

Vegan War

Vegan War was a pink cocktail with a strong basil fragrance, carrot cordial, tomato, and red cabbage. Its color made an immediate impression, followed by the herb’s sweet aroma. The carrot worked well with the tomato’s sourness, while the cabbage added depth to the combination. Our first thought was how refreshing it tasted, with the basil tying the vegetable ingredients together. It was a good example of the menu’s creativity producing a drink we enjoyed for its flavor as much as for its idea.

Inspiration: Dig for Victory

The menu connected Vegan War with Britain’s wartime encouragement to grow food. That vegetable-growing idea gave the ingredients a story beyond their place in the glass. We appreciated the connection with making more of what grows around us, a subject that still matters long after the original posters.

Yellow Union Flag

Yellow Union Flag brought together re-distilled green apple peel, apple juice, and coffee-cherry kombucha. Monkey Shoulder whisky and oolong tea gave the fruity combination depth, with osmanthus honey and soda completing the drink. We especially enjoyed the fizz and the caramel sweetness that lingered afterward. There was plenty in the recipe to keep us interested, and the apple remained easy to recognize among the tea, whisky, and kombucha.

Inspiration: A Chinese Poster Dated 1947

The drink’s menu entry referred to a Chinese propaganda poster dated 1947, connecting it with the menu’s wider interest in political imagery. In the glass, our lasting memory was the meeting of fruit, tea, and whisky, followed by that lively fizz. The poster supplied a starting point for the drink, and the flavors gave us something of our own to remember.

Waterbug

Waterbug was the drink most likely to test a guest’s expectations. An infusion and distillation of male waterbug supplied a fragrant, sweet character, supported by gin and re-distilled vodka. Bitters and lemon provided balance, while egg white and honey-almond syrup gave it a smooth texture. We particularly liked its slightly dry mouthfeel, which added another dimension to an already unusual drink. Knowing what went into it was part of the experience, and the flavor gave us a good reason to keep an open mind.

Inspiration: Nature Is the Real Treasure

For us, Waterbug raised a simple question about how much an ingredient’s appearance influences our willingness to try it. Once it arrived as a distillation in a balanced cocktail, we could concentrate on aroma, texture, and taste. We enjoyed all three. It was an interesting experiment in our own expectations, as well as in the bartender’s technique.

Cacao

Cacao brought us back to a flavor we already loved. The cocktail combined chocolate flavors with Thai Issan rum and was served in a cacao husk, which was enjoyable to hold as well as unusual to drink from. We found it difficult to put down. Its presentation also reminded us of a dessert from our fine-dining experience at Le Normandie, giving this particular drink a personal connection beyond the chocolate. Of the four, it was the one most closely tied to our fondness for cacao.

Inspiration: Thai Cacao

The drink’s Thai connection followed naturally from our earlier chocolate tasting at Kad Kokoa in Bangkok, where we had tried several Thai chocolates and struggled to choose a favorite. Liberation gave us another way to enjoy that ingredient. Here, the chocolate belonged in a cocktail, with the rum and cacao-husk presentation making the connection especially memorable.

Final Thoughts on Liberation Bar

Liberation was one of the Bangkok bars we enjoyed most for its willingness to explore ingredients. We remember the basil in Vegan War, the fizz and caramel aftertaste of Yellow Union Flag, Waterbug’s smooth texture, and the pleasure of holding the cacao husk. The dark room and helpful service gave those drinks a setting we liked spending time in. Its closure makes this an account of an evening that cannot be repeated there, and we are glad to have the photographs and tasting notes to remember it by.
