What Is Draft Beer? Vietnam’s Iconic Fresh Beer
What Is Draft Beer?
Draft Beer is a traditional Vietnamese fresh draft beer that is naturally fermented and typically not pasteurized before being served. Because it retains its natural yeast, active enzymes, and other beneficial compounds, Draft Beer offers a fresher, more aromatic, and fuller flavor than many bottled or canned beers.
Since it is unpasteurized, Draft Beer must be stored at a temperature of 2–4°C (36–39°F) and should be consumed soon after the keg is opened to ensure optimal quality. When kept refrigerated below 6°C (43°F), it can maintain its original flavor for approximately 20–30 days. If stored above 6°C for an extended period, the beer may lose its freshness, develop off-flavors, and eventually turn sour.
What Is Pasteurization?
Pasteurization is a heat treatment process used to extend the shelf life of beer. During this process, the beer is heated to approximately 70°C (158°F) and then rapidly cooled before filtration removes most of the remaining yeast.
This treatment makes bottled and canned beer easier to transport and store over long periods. However, the heating process also reduces the amount of active enzymes, soluble proteins, and some of the natural flavor compounds, meaning the beer loses part of its original freshness.
According to many brewing experts, fresh beer retains higher levels of beneficial yeast, active enzymes, amino acids, and soluble proteins than pasteurized beer. These naturally occurring components contribute to a richer taste, stimulate the palate, and create the refreshing character that many beer enthusiasts enjoy.
For this reason, fresh beer is often appreciated for its crisp flavor, natural aroma, and drinking experience that closely resembles beer straight from the fermentation tank.
Draft Beer – Vietnam’s Traditional Fresh Draft Beer
Draft Beer is one of the most popular beer styles in northern Vietnam, especially in casual beer halls, local restaurants, and neighborhood street-side eateries. It is brewed daily, undergoes a relatively short fermentation period, and is delivered to retailers in stainless-steel kegs to preserve its freshness.
It is a light-bodied lager with an alcohol content of approximately 4.1–4.3% ABV. Its crisp, refreshing taste, smooth drinkability, and affordable price have made Draft Beer a favorite choice for gatherings with friends, family meals, celebrations, and pairing with traditional Vietnamese dishes.
The Iconic Vietnamese Draft Beer Glass
One distinctive feature of Vietnam’s Draft Beer culture is the thick glass mugs made from recycled glass. Small air bubbles and tiny imperfections are often visible within the glass, reflecting the manufacturing process.
These glasses first became common during the 1970s, when raw materials were scarce and inexpensive, durable glassware was needed for mass production. Today, they have become an enduring symbol of Vietnam’s traditional Draft Beer culture and remain an essential part of the authentic drinking experience.
The Origin of Bia Hơi – Ha Noi Draft Beer
Draft Beer first appeared in Vietnam during the 1950s, when the country’s brewing industry began adopting European brewing technology. Among all regions, Hanoi became the most famous for its iconic Hanoi Bia Hơi.
Unlike commercially produced beer that is packaged in bottles or cans for long-distance distribution, Draft Beer is stored in stainless steel kegs, kept refrigerated, and delivered directly to local restaurants and beer halls within a short period to preserve its freshness and quality.
Today, Draft Beer has become an integral part of Vietnam’s street food and drinking culture, representing not only a refreshing beverage but also a unique social tradition enjoyed by locals and visitors alike.
Characteristics of Bia Hơi – Draft Beer
1. Unpasteurized
After fermentation, bia hơi is not pasteurized, allowing it to retain the natural flavors and aromas of malt and hops for a fresher, more authentic taste.
2. Short Shelf Life
Because it contains no preservatives and is not pasteurized, Draft Beer is best enjoyed within 3–7 days when stored at the proper temperature.
3. Low Alcohol Content
Draft Beer typically has an alcohol content of:
3%–4.5% ABV
Its relatively low alcohol level makes it easy to drink and an excellent companion to meals.
4. Light and Refreshing Flavor
Draft Beer is known for its:
- Clean, crisp finish
- Mild bitterness
- Light malt aroma
- Fine, creamy foam
- Refreshing and smooth drinking experience
How Bia Hơi – Draft Beer Is Made
The brewing process of bia hơi consists of the following main steps:
Step 1: Milling the Ingredients
The primary ingredients include:
- Barley malt
- Hops
- Brewer’s yeast
- Purified water
Step 2: Mashing
The crushed malt is mixed with hot water to convert starches into fermentable sugars, creating a sweet liquid known as wort.
Step 3: Boiling with Hops
The wort is boiled while hops are added to provide bitterness, aroma, and flavor balance.
Step 4: Fermentation
Brewer’s yeast converts the fermentable sugars into:
- Alcohol
- Natural carbon dioxide (CO₂)
- Flavor and aroma compounds
Step 5: Cold Conditioning
After fermentation, the beer is cold-conditioned (lagered) to allow the flavors to mature and stabilize, resulting in a cleaner and smoother taste.
Step 6: Kegging
The finished beer is transferred directly into stainless steel kegs, then delivered under refrigerated conditions to Draft Beer restaurants and local beer halls for fresh consumption.
