Castle Rock's Dan Mason has teamed up with the University of Nottingham to produce a beer celebrating the life, work and achievements of MRI pioneer Sir Peter Mansfield.

Sir Peter Mansfield spent much of his career at the University of Nottingham, and made some of his most crucial breakthroughs while there. Therefore, it seemed fitting to undergo some brewing experimentation at one of the university’s other facilities: the Centre for Brewing Science.

So Castle Rock’s Dan M teamed up with talented brewing student Matthew Davies with the brief of brewing something scale-able for Sir Peter Mansfield, bearing in mind that his favourite style of beer was a traditional session bitter. They decided on a base bitter recipe but decided that they wanted to try different hop bills with varying quantities and addition procedures. These hop additions are all based around a calculated 37 IBU (bitterness units), best bitter-style beer. They brewed three distinct beers on three grainfathers, and here’s an overview of each.

RECIPE #1

Malt:

  • Maris Otter Pale Malt
  • Crystal Malt
  • Torrefied Wheat
  • Amber Malt
  • Chocolate Malt

Hops:

  • Bittering (beginning of boil) – Sovereign
  • Flavour (end of boil) – Endeavour
  • Flavour/Aroma (hopback) – WGV

RECIPE #2

Malt:

  • Maris Otter Pale Malt
  • Torrefied Wheat
  • Amber Malt
  • Chocolate Malt

Hops:

  • Bittering (beginning of boil) – Sovereign
  • Flavour (end of boil) – Endeavour
  • Flavour/Aroma (hopback) – WGV

This recipe does not feature ‘Crystal’ malt in the malt bill. Depending on the roast, ‘Crystal’ can add anything from a light honey sweetness to a deep, bitter roast malt character to the beer. In this case, we are reducing the roast character in the recipe slightly.

RECIPE #3

Malt:

  • Maris Otter Pale Malt
  • Crystal Malt
  • Torrefied Wheat
  • Amber Malt
  • Chocolate Malt

Hops:

  • Bittering (beginning of boil) – Sovereign
  • Flavour (end of boil) – Endeavour
  • Flavour/Aroma (hopback) – WGV and Sovereign

In this recipe ‘Crystal’ malt was used and there is a larger quantity of of WGV added on the hopback, along with an addition of Sovereign so slightly amplify the hop character. Sovereign is a classic English-style hop with quite a complex aroma but typical descriptors include green tea, spicy, herbal, floral and earthy.


We have chosen our favourite, and the Sir Peter Mansfield brew will be upscaled and we will brew 22bbls (or approx 36 hl) on Wednesday 10th October 2018. We’re excited to see how this comes out and hope we do the style justice; particularly as this was Sir Peter’s style of choice on campus.

Towards the end of October we plan to launch the beer formally, and yes – we’ll keep you updated re: details!
