While it is true that canned kits are capable of producing decent home brewed beer, generally speaking, they cannot compete with our kits or kits that a brewer would design for him/herself.
There are several reasons for this.
Canned kits often come hopped which limits the control the brewer has on the final result of their beer.
They generally do not include specialty grains, which serve to improve the complexity and depth of a beer's character. Many call for the addition of table or corn sugar to attain the proper alcohol balance, but adding these sugars will “thin” the beer and contribute some off-flavors.Our kits supply you with all wheat and barley malt except where other sugars are appropriate for the beer style. The ingredients in canned kits can sometimes lack the consistent freshness that you get from our kits.
