Comparison
Dubbel vs Bock
What is the difference between Dubbel and Bock?
The short answer
The main difference is yeast fruitiness (esters): Dubbel has far more of it than Bock. Dubbel also leads on dryness and phenolic spice; Bock on bread & biscuit.
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
