THE BOIL
Boil time (mins): 60

Additions and timing:

35g East Kent Goldings @ 60mins
14g Celia @ 20mins
910g Clear Candi Sugar @ 15mins
680g Brewing Sugar @ 15mins

Secondary additions and timing:

Add yeast nutrient and finings (protofloc) at 15mins before the end of the boil.

Yeast: PLEASE SELECT ABOVE, either Wyeast 3787, WLP500 or LalBrew Abbaye. This kit comes with no yeast as part of the bundle, the brewer must choose one from our recommendation of another of their choice from our selection of yeast strains. Please use a yeast calculator to determine the quantity of yeast required, as this is a big beer.

Fermentation temperature/steps: 21c for 1-2 days then Ramp to 27-28c until fermentation has been completed.

This beer is a complex brew which involves both a stepped mash to unlock all the fermentable sugars from the malt, additions of sugar during the boil which will need attention and mixing in so as to avoid burning on the bottom of your boil kettle and finally a fermentation profile that involves warmth to accentuate the fusil warmth from the alcohol produced in fermentation.

For an even deeper flavour profile feel free to switch the clear Candi Sugar Syrup for either Dark Candi or Demerara Sugar

Once fermentation has been complete you will need to carefully package if you are choosing to use bottles. Maturation is vital so as to allow the flavours to round out, mellow and ripen. This beer needs to be enjoyed with a reasonably high level of C02 to create that distinctive ivory head and elevate the aroma from the beer.

  1. Jeremy Draper (verified owner)

    A monster brew. Technically difficult to get the stepped mash with a simple mash bucket, but I used additions of hot water to rise the temp at the required steps – crude but seems to work. The difficulty was getting all the sugars out in the sparge. I ended up with too much wort (23l prior to boil) but the SG was OK in the end. The rest was OK, including the stepped temp fermentation – the Lalbrew gobbled it all up.

    I felt there was a lot left in the grain, so left it for an hour or so and did another, separate sparge, collecting 17l @ 1.045 – enough for a ‘small beer’ with a separate boil & some home-grown Goldings. SG of this was 1.040 after the boil.

    The main brew is now bottled and maturing for Christmas, while the small beer is barreled and tastes OK, if a little thin. Early testing is all as it should be.
