A Brief History of Hops

This brew is my homage to Stephen Hawkins who sadly passed away while brewing this beer.  Its gravity may not be strong enough to form a black hole but it’s physics can still give one a headache.

Inspiration for making a New England IPA came from my previous brew of a milk stout. I wanted to combine the mouthfeel of a stout with the hop aroma of an IPA. This meant  adding flaked oats which would also of course produce a hazy beer. Hence the idea of a NEIPA.

This is the first time I’ve added hops during active fermentation. The theory being that the turmoil caused by the yeast helps to mix the hop pellets throughout the beer.

I spared no hop in the making of this beer. A total of 270g were used in this 19L batch.

Tasting Notes

  • Aroma was good but not as hoppy as I had hoped for. Considering the large amount of hopping, this was a little disappointing.
  • Mouthfeel was this beers best feature. Full bodied and round.
  • Taste started off nice and sharp but the bitterness slowly grew to excess.

Salt Contributions (palmers water calc spreadsheet)
Calcium (ppm) =84
Magnesium (ppm) = 17
Alkalinity from Hydroxide =0
Alkalinity from Bicarbonate =104
Sulfate (ppm) = 69
Chloride (ppm) = 149
Sodium (ppm) = 48
Adjusted Residual Alkalinity as CaCO3 = 60
Adjusted Sulfate to Chloride Ratio = 0.5

Hot liquor pre salt additions pH=3.3. I believe this is due to residual Star San.
Hot liqour post salt additions pH=6.5
Mash was too dry. Went for a no sparge. Added another 14L at 75 degrees.

* SOFT ERR - No flow sensor events during kettle to mash at start of mash.
* SOFT ERR - Preheat temp was set to a constant 80. Not accounting for grain temp etc
* HARD ERR - Valve 7 is dodgy.

Mash started 2005
Mash restarted at 2030
Mash temp = 50. Pumped back to kettle and heated to 70 before pumping back to mash tun.


* BREW ERR = Mash was way too wet. Looks like 40L in the MT. Added another 2Kg extra pale maris otter (3 EBC). This may be a mistake

Mash re-restarted at 2100 with a temp of 63C

Boil start 2250.

25th Mar: SG = 1.060. Calculated SG = 22.06/20=1.103 =>V=20.81

28th Mar: SG = 1.023. Calculated SG = 21.4/20 = 1.070 =>V=20.92
Removed 100ml

Added 50g of Columbus and 40g of Magnum pellets at 1910 on 29 Mar. NB increases SG.

31 Mar: SG = 1012 => 6.3%

3 Apr: SG=1013 =>6.2%

Stopped Fermentation on 3 Apr

9 Apr: Closed transfer to purged keg using CO2. Set to 20 psi.
