Ingredients (All Grain5.5 gal)

  • 8 lbs Pale Ale Malt; Bairds Malt

    Pale Ale Malt; Bairds Malt

    Pale Ale malt forms the majority of the grist for a typical U.K. Pale Ale or Bitter beer and is made from some of the best barley available. There is an emphasis on single variety and low protein levels. The barley will be fully steeped and germinated before the green malt is loaded to the kiln. Kilning is a carefully controlled process removing moisture to a relatively low level without destroying excessive amounts of enzymes but imparting characteristic flavour and colour. Even with a diastase of only 45°L there is still enough activity to convert for example 5% of Crystal malt and 5 -10% of cooked adjunct (e.g. flaked maize). Mashing is normally at a fixed temperature of about 65°C, so modification has to be high to cope with this and a coarse grist is normally used. Many UK brewers stress the flavour benefits in the wort and glass of using Pale Ale malts produced from traditional winter malting barley varieties.

This was a good beer. It was a little too roasty for my palate, but very smooth and drinkable nonetheless. I especially liked the hops in this beer. I think the Nugget addition carried through and seems like a really nice hop for porters and stouts.
