Hop Experiment – Cashmere, Rakau, and Galaxy in IPA

Premise and Recipe

I’ve been wanting to try out Cashmere hops since I heard about them last year. In the summer, I was able to find a nursery that sold field-ready plants, and was able to pick one up. Unfortunately it was late in the season, and I wont get a good crop for a couple of years anyways.

However, a couple of weeks ago, I was looking on the Short Finger Brewing Co website, and found that they had some in stock, and from a local Southern Ontario hop farm! Excited, I looked through their other locally-sourced hops, and thought I’d try some Rakau hops, which I have not had the chance to use before. I also had some Galaxy hops in my freezer which I have been itching to use again, thus giving me 3 feature hops to use in a good hop-centric beer.

In trying to figure out what to brew with these, and how to get a good few brews in, I devised a plan to split a 23L batch of IPA into 3 separate kettles mid-boil (post-bittering), then adding my late addition hops to each split. Following chilling, I would ferment in 6 160oz (4.75L) jugs, and dry hop in half of them with their respective featured hops.

After looking through a few IPA recipes, I built mine on the low gravity side, but still enough to provide a good backbone to the hops. Canadian 2-Row for base malt, light munich for bready flavour, dark caramel (30/35) munich for residual sweetness, some caramel 120L for some raisin notes, and a handful of Cara-Pils for head retention.

For a bittering hop, I usually use Magnum for its clean properties and high effectiveness. 15g is enough in a 23L batch for 20 IBUs, and as I’m trying to highlight the late additions and dry hops, I don’t want to go overboard on the bitterness, that should be enough.

I heated my strike water and mashed in a little lower than expected, but not far off the mark (66.1 instead of 66.7).

Not too shabby!

While mashing, I divided up my hop additions and got organized for the boil.

After conversion, I drained the first running from the grain bag, and I batch-sparged in the kettle, and drained again.

That gave me a pre-boil gravity of 1.040 with about 26L of wort, pretty close to the brim of my kettle: time for FermCap S! Also time for First Wort bittering hops.

The first 50 mins of the boil were business-as-usual. Then I checked the boil volume and divided into 3 equal parts into 2 additional pots to continue their boil inside on my stove.

Now that the boil is divided, I added my chiller for sanitization, and proceeded with my feature hop additions (also 1/3 of a whirlfloc for each pot)

After my additions, I whirlpooled and chilled each batch and put them in my ferementers.

I re-hydrated my US-05 and pitched, setting my fermentation temperature to 18 degrees for 7 days, then slowly raising it to 20 following that to ensure full attenuation.

More details to follow when fermentation is done!

One of the things that drew me to brewing beer at home was the opportunity to make beers that simply are not available commercially here in Canada. I visited the Samuel Adam’s brewery in the fall, and was able to try a sample of a Flander’s Red Ale that they brewed for a competition: I… Continue Reading
