Sept 15th IPA

Sept 15th IPAAs I’ve journeyed through my homebrew hobby, I’ve taken more interest in cloning commercial beers.  It’s a challenge undertaken by many homebrewers and for some people, I suspect, the inspiration to get into homebrewing.  The Can You Brew It? series on The Jamil Show is just one indicator of the immense interest in replicating commercial beers.  One of the first beers that I tried to clone was Phillips Amnesiac Double IPA.  Unfortunately, the first batch fell well short of the mark.  So on Sept 15th, I thought I’d try again.  Alas, it was another failed attempt – but it yielded what I’m (creatively) calling Sept 15th IPA .  Why did it fail?  Aside from some tweaks like using Magnum, Zeus and an absence of Citra – what really killed it was poor mash efficiency.  I bought a Monster Mill 2 and I couldn’t set the gap to crush the grains enough.  I’ve since figured it out and have seen a return to 60+% efficiency, but this was failure #2 for an Amnesiac clone.  Luckily, the failure tastes pretty decent.  The result was a very bitter IPA, rather than a double IPA.

Appearance – Pours medium amber colour with inch of initial head that diminishes to a fine layer, but leaves lacing from top to bottom. Light hop haze.

Aroma – Aroma isn’t as fragrant as I would like.  Spicy hop aroma prominent.  Subtle grapefruit smell in the background.

Taste – Strong, clean bitterness with mild tropical and grapefruit flavours.  Slightly sweet finish balances the strong bitterness.  But I’d like if the tropical and grapefruit flavours were stronger.

Mouthfeel – Carbonation is medium-low and the beer is smooth.  Goes down easy.  Bitterness leaves a lingering dryness.

Drinkability/Notes – No technical flaws that I can identify in this final bottle of the batch – but some bottles had a bit of a cardboard flavour, indicating oxidation.  Definitely a bitter IPA, but I’d prefer if it had fruitier notes.  The early bottles that I drank were fruitier, but the bitterness was overpowering.  Time has mellowed the bitterness, but the fruity hop flavours were considerably diminished.  Overall, for a beer that was a failed clone attempt – it’s something that I’ll base a recipe upon in the future – but I’d prefer not to deplete my precious supply of Maris Otter to learn these lessons.
