Freshness matters when it comes to taste. Typically keg beer will be consumed closer to the time that it left the brewery than bottled beer.
No Oxidization with Draft Beer
Beer is brewed with natural ingredients i.e. hops, malts, and yeast. These natural ingredients are prone to oxidization, which will negatively impact taste. Super fact: a keg contains less air than a bottle.
Just Brewed Taste Thanks to Cold Delivery and No Pasteurization
Domestic beer that is intended for bottling undergoes pasteurization. This means that the finished brew is heated to kill off any bacteria that may grow between the time of bottling and the time of consumption. And you know what heat can do to flavor – it puts it in jeopardy.
Domestic keg beer does not require pasteurization and is kept consistently cool from the brewery to the distributor to the local tavern. In fact, most domestic kegs are kept cold right up until the time that the tap is opened and poured into the glass. This ensures flavor is retained.
Beer is a Food Product that does not Enjoy Sunshine
Lightstruck is not a good thing. When light reacts with the hops in beer, it causes a reaction and the taste can change to bitter. We don’t like being kept in the dark, but trust us, keg beer is always kept in the dark to prevent bittering.
Maintain Freshness with Clean Beer Keg Lines
Dirty lines can affect the taste of draft beer, so keeping the lines clean is vital. Beer lines need to be drained and cleaned every two weeks. This is the standard set by the industry trade group Brewers Association. Ask at your favorite tavern, “When were your lines cleaned?” With so many excellent choices on draft, the best line at the bartop is “make mine a draft!”
