#1 Summer Jam IPA

#1 Summer Jam IPALately Gregory and I have been honing recipes for a few different “house” IPAs.  I recently wrote a New Zealand/Australian hop-heavy session IPA recipe for the spruce tips Gregory and I foraged this past spring.  We liked the resulting beer so Gregory tweaked the recipe and brewed a version of it for the wedding of a friend.  I tried that version and liked it as well, but I decided to go back to the grain bill of the original recipe for inspiration, and make a third, PNW hop-forward beer.

I wanted to create a beer of “normal” strength that showcases the intense tropical, floral, and citrus notes of the new classic American hop varietals while remaining smooth, crisp and quaffable.  I stuck to a grain bill of pale malts with a touch of flaked oats for a silky mouthfeel and appreciable body, and rye to provide head retention and subtle grainy-spicy complexity.

I’ve also been looking forward to experimenting with blending different clean yeasts to create a more complex and flavorful ester profile, so I used two different saccharomyces strains in this brew.  I wanted to use Imperial’s A24 Dry Hop yeast, but the homebrew store was out so I opted for their A20 Citrus strain.  I pitched this first and then pitched a starter of yeast slurry 33 hours into primary from the wedding IPA — which utilized Imperial’s English A09 Pub yeast strain.

The resulting beer turned out great and the methods used to create it highlight our continual striving to craft better and better beer.  Unfortunately, I bumped the keg shortly before the photo was taken, so some hop particles were stirred up (I would have waited and taken another photo, but the beer was already almost gone)!

Below is the recipe and process that we used, as well as tasting notes:

Tasting Notes — 08.16.16 (poured off tap)

Hazy yellow-orange with a moderate white head stand which laces nicely.  Aromas of pineapple with a spicy-herbal/tropical note reminiscent of mango salsa, hints of lime and dill.  Herbal and fruity flavors dominate the palate with notes of grapefruit and orange as well as pineapple, cedar and pine.  Body is lush and juicy, but crisp and finishes with a dry and resinous spicy-floral bitterness.

HOP SLUDGE! American India Pale Ale

HOP SLUDGE! In A GlassIn May 2015, Gregory and I entered three different IPAs into the Greater Everett Brewers League (GEBL) IPA Bracket Challenge.  We brewed an English style IPA, an American style IPA and an American style rye IPA (this last with Johnny Bus Tickets).  Sadly, none of these beers placed in the competition (although the rye IPA was bumped out of its bracket in the last heat).

When we got our score sheets back from the judges, we noticed that each stated they thought our American IPA (which is a recipe we’ve been tweaking since Gregory first brewed it for a friend’s wedding) was a great example of an XPA (extra, or hoppy, pale ale); what they wanted was more bitterness.  So we went back to the drawing board, made some adjustments, added more hops to our bittering additions, and thus HOP SLUDGE! was born.

HOP SLUDGE! 02We jokingly named the beer while we were brewing it because the massive amounts of late addition hops created a sludge of hop particulate in the kettle, and subsequently took up about a fifth of the space in our carboy.  The beer crystallized the name itself when fermentation took off so quickly and aggressively that the rubber stopper and blow-off tube were shot out of the carboy and delicious, tropical-smelling wort metamorphosing into beer was showered across the basement floor.  Luckily I caught the problem shortly after fermentation started and was able to get everything cleaned, re-sanitised and proper before any bacteria could settle in.

HOP SLUDGE! 01I’m convinced this is the finest IPA we’ve made yet, but we’re already thinking of changes that can be made and new recipes entirely.  See our recipe and tasting notes below:

Notes

Brewed on 11.05.15 with Gregory

11.05.15 — Chilled wort to 60F and pitched the ale yeast (no starter as ran out of time before brew day)

11.06.15 — Signs of vigorous fermentation activity (see description above)

11.09.15 — After four days of primary, as fermentation began to slow visibly, we added half of our dry hop addition for a 6 day dry hop

11.15.15 — Transferred to secondary after 10 day primary and added the rest of our hops for an additional 5 day dry hop

11.20.15 — Kegged and began force carbonating the beer

11.27.15 — Took the first pull from the keg after a week, still quite cloudy but tasting good

HOP SLUDGE! 03Tasting Notes — 12.14.15 (poured off tap)

Although much clearer than the first pull from the keg, it has remained a little hazy (probably due to the amount of late addition and dry hops we added without filtering afterwards).  Intense tropical fruitiness on the nose, bringing papaya and mango to mind, with notes of lush pink grapefruit, some honeyed malt sweetness, and a hint of resinous evergreen akin to fir or pine.  The palate follows the nose, but the tropical notes are more muted at first, allowing the Chinook’s earthy spiciness to shine through.  The resin and evergreen hit the sides of the tongue toward the finish and a crescendo of fruitiness briefly re-emerges right before the substantial herbal-spicy bitterness takes hold for a dry, lingering finale.
