Recreating Brakspear Bitter with Historic Drop Fermentation
In this week’s video, James recreates a beer that genuinely shaped a brewing journey — even if it wasn’t obvious at the time — Brakspear Bitter.
Brewed for generations in Henley-on-Thames, Brakspear became famous not only for its balanced, sessionable bitter, but also for its “double drop” fermentation system. This historic method helped define the character of its beers and secured its place in British brewing history.
This isn’t just another all-grain brew day. It’s a deeper look at how heritage methods, yeast handling and fermentation techniques shape the flavour of a classic British pint.
Why Brakspear Bitter?
For many of us, beer carries memory.
The first proper pint.
The local pub bitter.
The beer that made you realise there was more to brewing than just following a kit.
This recipe is about revisiting one of those beers — not simply cloning it, but understanding why it tasted the way it did and how traditional fermentation methods influenced its character.
We explore the distinctive Thames Valley bitter profile and what makes it different from other regional styles across the UK.
What Is Drop Fermentation?
Brakspear’s historic “double drop” system involved transferring actively fermenting beer from one vessel to another mid-fermentation.
The process helped:
-
Separate excess trub and less flocculent material
-
Encourage healthy yeast activity
-
Promote ester development
-
Shape the brewery’s distinctive house character
In this video, we explore whether a simplified version of that technique can be adapted for modern home brewing — and what impact it has on flavour, attenuation and overall beer character.
We also look at the wider context of traditional British fermentation systems, including the famous Burton Union system and how historic yeast management influenced flavour development across generations of breweries.

Brew Day Approach
This is a full all-grain brew day focused not just on the recipe, but on process.
We walk through:
-
Grist selection for authentic bitter character
-
Hop choices for traditional English balance
-
Yeast selection and fermentation management
