02/03/2014 – Brew day, got slightly less than usual volume (about 18.5l) into the fermenter, but OG was spot-on. Less than 100g of hops in this recipe, so I had no trouble draining off the wort and got a pretty clear wort. Strange thing was, there was still a lot of flecks of cold break, despite leaving it for ages in the boiler before transfer to FV. Huge amount of foam in FV before pitching yeast.

03/03/2014 – Massive overspill from the FV!! Could it be the wheat malt. I really didn’t expect this from a moderate gravity beer that is being fermented in the coldest room in the house. The only thing I can think of is that I must have massively overpitched the yeast. Seems to have calmed down now. Will monitor for a couple of days.

17/03/2014 – Bottled with 120g glucose (18 litres @ 2.5 vol), but got only 34 bottles from the batch (17 litres). Great beery, grainy smell from the fermenter. Looks quite murky though.

15/04/2014 – First taste, not too bad. Tastes a tiny bit yeasty at first, then it settles down a bit and some of the toasty, grainy flavour comes through. I’d say (hope) it will improve with another couple of weeks conditioning. Although I was trying not to make a hop bomb, I can’t help thinking “needs more hops”. Old habits die hard. Level of crystal malt is nice, lots of spiky bitterness poking through. Very dry finish.

19/04/2014 – The bottle I’m tasting at the moment is markedly better than the one I tasted only 4 days ago. Crisp and malty, but with a lovely residual sweetness to balance the assertive hop bitterness. Hops coming through quite nicely, but it’s not a hop bomb. This is the kind of beer I can’t wait to have on tap. Think I might have found my regular pale ale recipe.
