RealBrew™ | Cryogenic Fermentation
RealBrew is our cold-fermentation process. It lets us brew our beer at 0.5% ABV from the start and keep it at its brewed strength.
We brew with Social Blend for that relaxed, sociable beer feeling.
How cryogenic fermentation works
RealBrew starts with the same ingredients you would expect in a beer: water, malted grain, hops and yeast. The difference is how we control fermentation, so the beer develops at low alcohol from the start.
Start with malt, hops and yeast
In beer brewing, malted grain is mixed with water in a stage called mashing. Enzymes turn starch in the grain into sugars, producing a brewing liquid called wort. Yeast uses those sugars during fermentation, producing alcohol.
For our Enhanced Lager, we brew with real barley and wheat, using a recipe based on a premium Japanese lager. Malt also contributes body and flavour, while hops bring bitterness and aroma.
Keep fermentation cold
Temperature affects how yeast works. We use cryogenic fermentation: brewing at very low temperatures so the yeast produces very little alcohol.
That is how we reach 0.5% ABV through brewing itself. A small amount of alcohol still forms naturally during fermentation, which is why the can says 0.5% rather than 0.0%.
The cold temperature controls alcohol production. It does not remove alcohol from a finished, full-strength beer.
Keep the beer at its brewed strength
Some alcohol-free brewing methods start with a full-strength beer, then remove the alcohol using processes such as heat or vacuum distillation. Removing alcohol can also affect the beer's aroma, flavour and mouthfeel.
RealBrew leaves out that alcohol-removal stage. We don't brew a strong beer and strip it back afterwards, or dilute it with water to reach 0.5%. What we brew is what you drink.
When we say we don't boil the alcohol out, we mean there is no heating stage to remove alcohol from the finished beer. The temperature control happens during fermentation.
Build flavour with hops and conditioning
Low alcohol is only one part of the job. Our Enhanced Lager is dry-hopped and extensively conditioned for flavour.
Dry-hopping brings out hop aroma, while conditioning gives the beer time to settle and develop its finished character. In the lager, that means a crisp, refreshing beer with a clean, lingering citrus finish.
These are details of our lager recipe. Each beer in the range has its own flavour profile.
Brew with Social Blend
We also brew with Social Blend, our blend of functional ingredients developed for relaxation. It includes L-theanine, ashwagandha, vitamin B1 and plant extracts.
L-theanine is an amino acid found in tea. Ashwagandha is a plant whose root is used in the blend, and vitamin B1 is also called thiamine.
Why the lager can be gluten-free
Our Enhanced Lager uses an enzyme process that breaks down gluten, while keeping barley and wheat in the recipe. The lager meets the gluten-free standard of less than 20 parts per million.
Gluten-free does not mean wheat-free. The lager still contains barley and wheat, so that distinction matters if you have a wheat allergy.
Where the relaxed feeling comes from
We brew with Social Blend, our blend of functional ingredients developed for relaxation. RealBrew is how we brew the low-alcohol beer; Social Blend is what we use for that relaxed, sociable beer feeling. People respond differently.
Why does it say 0.5%?
A small amount of alcohol forms naturally during fermentation. Trace alcohol also occurs in foods and drinks such as orange juice; the amount varies.
0.5% means low alcohol, rather than zero alcohol. If you need to avoid alcohol completely, use the ABV on the can to make your choice.
