The Evolution of Brew-in-a-Bag (BIAB) Brewing: Unibrau Brew System
Pictured below is the first version of the Unibräu Brew system released in 2014.
The Birth of BIAB: A Retro Revolution
BIAB brewing has deep roots, dating back to its early beginnings as a simple and efficient method for creating flavorful beer. Over the past half-decade, it has experienced a resurgence in popularity, captivating the hearts of homebrewers worldwide. This revival comes as no surprise, given the multitude of benefits that BIAB offers to both newcomers and seasoned brewing enthusiasts.
As a former devotee of the traditional three-vessel brewing setup, I can attest to the allure of BIAB. Despite investing significant time and money into my elaborate system, I eventually realized that BIAB brewing held a distinct advantage. With BIAB, achieving the same flavor profile as high-end professional brewing systems becomes attainable. Additionally, BIAB systems are compact, easy to set up, and require less equipment, translating into cost savings and space efficiency. Some BIAB setups even eliminate the need for household electrical modifications. Plus, as long as you're using a nylon bag – which is inert and non-leaching – concerns about steeping it in hot wort become a thing of the past.
However, the most compelling advantage of BIAB is the time it saves. While a brew day can consume a laborious eight to nine hours with a traditional three-vessel system, BIAB can have your brew in the fermenter in under four hours.
Dispelling the Efficiency Myth
One commonly held belief about BIAB is that it sacrifices efficiency for convenience. Traditional three-vessel setups, known for their thorough grain rinsing to maximize sugar conversion, can achieve up to 90% efficiency. In contrast, the standard brew-in-a-bag method typically yields around 65% efficiency. However, with a few savvy techniques, you can boost your BIAB efficiency to at least 80%, narrowing the gap and mitigating any potential losses.
One significant efficiency boost comes from starting with an exceptionally fine grain crush. Requesting a double crush from your local homebrew shop is a wise move. Concerns about extracting excessive tannins in the beer due to a finer crush are unwarranted in BIAB, as the faster process minimizes the risk of tannin extraction.
Next, extend your mash time to 90 minutes instead of the standard 60 minutes. This ensures complete sugar conversion and contributes to enhanced efficiency.
For an extra gravity boost, consider this trick: heat a large pot of water on the stove to the mash-out temperature and rinse your grains after removing them. Place the grains in your primary bucket or a suitable container, then rinse them with water at the ideal mash-out temperature of 168 degrees Fahrenheit. Collect the rinse water and pour it into the boil, maximizing your volume from the small brew system and increasing efficiency by up to 10%. Don't forget to subtract your mash addition from your initial strike volume for accurate measurements.
Lastly, find a way to squeeze or press your grain bag before discarding it. This simple step can yield a bit more wort, which is denser and more concentrated, making it well worth the effort.
Managing the Mess and Safety
One minor downside of BIAB brewing is the potential for messiness, but this can be easily remedied with proper preparation. First, ensure you're using a system that incorporates a basket or mash screen over the heating element to avoid any risk of melting through your bag.
Second, be prepared to handle the hot grain bag when it's time to remove it. For larger batches, you might be dealing with a scalding-hot bag laden with saturated grains, weighing upwards of 25 pounds. If you lack the strength to lift it safely without spilling your precious wort, consider installing a hoist. Keep a five-gallon bucket nearby, or position your brewer close to the sink, allowing you to safely dump the bag to cool. Beware of the scorching heat emanating from the grains, as it can cause burns.
