The specific advantages of the Duotank concept have led to it being increasingly adopted by microbreweries and brewpubs. This popularity is partly due to the fact that the beer retains its flavour longer after being connected to the beer taps, (many major breweries guarantee up to 12 weeks!), making it ideal for the specialty beers that often have somewhat lower turnover. This is because no extra CO2 needs to be added to the beer, and the beer is kept at a constant temperature and pressure; these factors significantly help preserve the quality of the beer and increase customers’ enjoyment of the flavour.
