Cubista Pocket Water Double IPA

by @dekasso

Spray, dark stone and gold light

A double IPA named for the Rio Cubista, resinous and citrus-bright at 8.5%, for a slow evening by fast water.

Brewed to order

Cubista Pocket Water Double IPA wears a label of angular fish swimming through swirling teal current. The design is cut into navy, teal and gold shards with cream lettering, set beside white rapids.

In the glass

7SRM

Grapefruit, ripe mango and pine resin over a honeyed malt middle, with a firm, dry bitterness

Serve
45°F in a tulip glass
Alongside
Spicy fish tacos, sharp cheddar, grilled sausage

Fish cut into blue, teal and gold shards swim through a spiral of current on a navy label. Behind them, white water breaks over dark rock, and the whole thing rests on a grey, weathered plank.

Grapefruit and mango up front, then pine resin and a honeyed malt middle. The bitterness is firm and the finish dry, so the 8.5% sits quietly. Open one when the waders are hung up and the light goes gold.

Dry hopping needs care here. Purge the fermenter with CO2 first, add the Citra and Simcoe on day 10, and keep oxygen out so the fruit stays bright.

Grain bill

3 malts · 15.5 lb for 5 gal
Piles of pale, amber and dark malted barley on a wooden bench beside a scale.

Milled grain, weighed for each batch size. The percentage is each malt's share of the grist and stays the same at every size.

Hop schedule

6 additions · 60 min boil
Whole green hop cones and hop pellets on slate, one cone split to show the yellow lupulin.

Pellet hops, weighed in grams. Boil times count down to the end of the boil, so 60 minutes means the first thing in the kettle.

Water

8.49 gal into the mash for 5 gal

Full-volume brew-in-a-bag: all the water goes in at the start and there is no sparge. Volumes are the total to heat, so the kettle has to hold the mash and still leave room to boil: the 12-pack kit sells a 5 gal stockpot and the 12×12 kit a 30 gal kettle for that.

Boil-off, grain absorption and trub are typical figures for a stovetop pot and a propane kettle, not measurements of your own gear. Brew once, note what you end up with, and adjust. House guidance

Water profile Soft water with sulfate near 150 ppm and chloride near 75 ppm keeps the bitterness crisp.

Mash

150°F · 60 min

The mash turns starch into sugar. Hold the temperature steady and the beer finishes the way the recipe intends.

  • Rest150°F for 60 minutes
  • Strike waterHeat to 160°F; the grain cools it to the rest temperature. House guidance
  • Mash-outRaise to 168°F and hold 10 minutes, then lift and drain the bag. House guidance
  • Mash ina cooler rest keeps the finish dry under all those hops

Boil

60 min · 4 hop additions

Hops go in on a countdown from the end of the boil. Early additions give bitterness; late ones give aroma.

Packaging and carbonation

2.5 volumes CO₂ · bottle or keg
Plain aluminium cans and a small keg on a workbench beside a priming-sugar measure.

Target 2.5 volumes of CO₂.

Dissolve the sugar in a little boiled water, stir it gently into the beer, then bottle. The amount is worked out for 68°F, the warmest the beer got while it fermented.

Kegging Set the regulator to 11.2 psi at 38°F.

Kegging instead Skip the bottles with 3 × 5 gal ball-lock kegs, 1 × 5 lb CO₂ tank, 1 × dual-gauge regulator, 1 × gas and beer lines with picnic taps: the kegging upgrade for the 15 gal home brewery, $594.

Brewer's notes

3 tips
  • Oxygenate the wort well before pitching; a big gravity needs a strong start.From the recipe
  • Purge the fermenter with CO2 before dry hopping to keep the aroma bright.From the recipe
  • Drink it fresh; the hop character fades within a few weeks.From the recipe
