Comparison
Doppelbock vs Bock
What is the difference between Doppelbock and Bock?
The short answer
Doppelbock and Bock are closer than the comparison suggests. The measurable differences are small — yeast fruitiness (esters) is the largest of them — so tradition, strength and what each is brewed for will tell you more than the flavour axes do.
Generated from the two style records. No editor has written this comparison up, so it carries no verdict beyond what the data supports.
Where they overlap
