MAC Goto

Yet another go a brewing a Goto IPA. This time I tried the MAC hops. Mosaic, Amarillo and Citra. The grain bill was also changed significantly. To lighten the colour, I went for 50/50 Maris Otter and Pilsner, with a little wheat malt for head retention.

Not surprising the increased grain bill resulted in healthy 6.7% ABV. Tasting post fermentation and pre dry-hopping was a little sweet at 1020 F.G. But what I found amazing was the change in taste after dry hopping. It changed from a slightly sweet alcoholic taste into a wonderful pineapple flavour.

However, after a few weeks after carbonating and bottling things turned south, The delicious pineapple aroma had gone.  To make matters worse, the colour had darkened significantly. Turning this beer from a pale aromatic delight into something mediocre and brown.

Still, I immediately planned my next brew to fix my perceived mistakes using a different malt bill and process to avoid oxidisation. Fingers crossed.
