VELVET THUNDER - Imperial Stout Recipe

Beer of the Month Program

December 2020 - VELVET THUNDER -  $59.99 $64.49

One of the best parts about making beer (aside from drinking it) is the social aspect. Brewers love to swap recipes, discuss what well or horribly wrong in their brews. We thought it would be a fun idea to start a beer conversation here. We're going to make a beer every month here and encourage other brewers to make it as well. In the end, we're hoping we can share our opinions and experiences with the recipe and crowd-source some improvements. The recipes will be easy to make and we will gladly assist new home brewers in the production of these beers. They will all be 5.5 gallons in size. We find that after fermenting and racking a 5.5 gallon batch turns into a standard 5 gallon batch pretty quickly.

At the start of every month we will post the recipe in store, as well as on our websiteFacebookInstagram, and Twitter. We will also have a set price for the recipe that will include a discount of up to 25%!

VELVET THUNDER

Purchase This Recipe Online (light version)

Imperial Stout – 5.5 Gal - OG 1.089 – FG 1.016 – ABV 9.4% - IBU 52 – SRM 47

My wife and I (Connor) were re-watching Brooklyn 99 and in one of the final scenes in season 2, episode 22 (it’s on Netflix!) Holt became my favourite character. He tells Jake. Call me…. VELVET THUNDER in his perfect, Shakespearian voice. Right then, I knew we needed to name a beer after that. But, what kind of beer is worthy of the name VELVET THUNDER?

I knew it had to be a big, bad imposing imperial stout. Classy enough for Captain Holt, but brash enough to justify the name. This beer is BIG. It is a whopping 9.4% ABV. It is thick, opaque with a large dark brown frothy head. It had extremely rich notes of chocolate, coffee, and lovely malt character. Its balanced out by our newly arrived 2020 hops, and it features one of our favourite yeasts – Cali Ale from Escarpment Labs.

So, spend this winter watching (or re-watching) 99 and sip on a rich glass of Velvet Thunder.

Note: As we’ve mentioned, this is a BIG beer. So, for those that don’t want something as big as this or don’t have the equipment to brew an imperial stout – we have made a lighter version of this recipe.

Important Tips on Brewing
  • Be extra cautious when it comes to cleaning! Once you have stopped boiling your wort everything that gets in contact with the beer MUST be sanitary.
  • The temperature of your mash is ABSOLUTELY CRITICAL. Not being in the 150-155f range can drastically affect your beer. Make sure you correct the temperature ASAP once all of the grain has been added to the mash.
  • Always let your beer ferment for 10 days! Do not disturb it, do not open the lid. It is absolutely natural for the airlock to stop bubbling after a few days, it is still fermenting though.
  • Oxidization: Airspace is always something to consider. When undergoing primary fermentation airspace is needed so that the beer can bubble up and ferment vigoursley without leaking out of the container. The fermentation creates a layer of CO2 that remains in the pail due to the airlock. Once primary fermentation is over, and the lid has been opened, the layer of CO2 dissipates, and oxygen replaces it. At this point airspace can ruin your beer. When racking into carboys make sure they are filled to the top, or you blast CO2 inside to prevent oxidization. Ask us for details on this!
  • Before bottling, make sure you use a priming calculator (many can be found online) to verify the amount of sugar that needs to be added.
  • What's the deal with the acidulated malt? If you're using Guelph water, or any tap water from Ontario it is almost always very hard water. Hard water has a high pH, in order to get the pH down to the proper level for brewing we recommend adding 2.5-3% acidulated malt to your beer. It depends on the style a bit, but this is a good rule of thumb. Get in touch with us if you'd like a more in-depth explainer of pH and water adjustment!

Instructions

Special Notes on This Recipe:

This is a BIG recipe. Most recipes have 10-12lbs of grain and this one has 17.5 plus 500g of dextrose! If you are producing this with brew in a bag, an 8-gallon pot will not be big enough. A 10-gallon pot will be the minimum. If you are using a mash tun then an 8-gallon pot will be no problem. The issue is the amount of grain displacing all of the water in the smaller pots. Alternatively, you could split up the mash into two bags and two pots. If this is not possible, we have also produced a smaller version of this recipe which can be brewed BIAB style with 8-gallon pots.

Also, because there is so much fermentable sugar there needs to be an appropriate amount of yeast and nutrients to get a good fermentation. We recommend adding two packages of Cali Ale (both packages are included in the price), or alternatively you can make a yeast starter with a fresh Cali Ale and use that instead (and save $11 in the process.). We also add yeast nutrients in the final fifteen minutes of the boil to give the yeast a helping hand.

Mashing -> converting the grain into a fermentable liquid.

  • Bring 7 gallons of water (6 gallons if you are doing the light version) in your brew pot to 155°F. This is our strike temperature. Turn off the heat to the pot.
  • Wrap the muslin/nylon bag around the brew pot and slowly pour all the milled grains into the bag. Stir them in while adding to prevent clumps. The addition of grain should drop the temperature down to 150-155°F.
  • We want to mash the grain at 154°F for 60 minutes. It is very important to hold the temperature at 154°F. If the temperature rises above 155°F it hurts the fermentation, or if it dips below 149°F it can lead to a thinner tasting beer.
    1. The first 15-30 minutes are essential for the success of your brew. The temperature HAS TO BE IN THE RANGE OF 150-155°F. Sometimes adding the grain to the strike water does not lower the temperature enough, in this case add a little bit of cold water to bring the temperature down. Cover the pot with your lid and let it sit.
    2. Most brew pots will be able to maintain 154°F without adding heat for 20 minutes, we recommend checking the temperature every 15 minutes, and if it drops add more heat to bring it up. We recommend opening the lid and using a thermometer in the liquid.
  • After 60 minutes, bring the temperature of the mashing grain up to 170°F and hold for 10 minutes. This is our mash out.
  • Time to remove the grain. Lift the bag full of grain out of the brew pot. Let the liquid in the bag dribble into your wort. Once that is done, put the bag inside of a brewing pail, or another empty pot. There will be about 4 gallons of wort in the brewpot, we need to get it to 6 gallons before we can begin the next stage.
  • Run warm water through the grains in the bag, aim for 170°f – let it run through the grains and add to the brewpot. Add until you reach 6 gallons.
    1. PSA: It is natural to think that the grains need to be squeezed to get all of the liquid out of them, DO NOT DO THIS. Aggressively squeezing the grains will lead to tannin extraction and a doughy taste in your beer. Lightly pressing the bag is fine, but do not try to squeeze every last drop out.

Boiling -> Hop addition time

  • Bring 6 gallons of your wort to a rolling boil, and let it boil for 5 minutes, this is called the hot break.
  • Add 1oz of Columbus hops to the pot and set a timer for 60 minutes, (if doing the light version, add 1/2 of Columbus instead) keep the wort boiling (212°f) and uncovered.
  • With 15 minutes left in the timer add the Irish Moss, 2 ounces of Centennial, 1 tsbp of Yeast Nutrient, and 500g of Dextrose.If you’re using a wort chiller add that too. (Don't add the dextrose if you are doing the light version)
  • When your timer goes off, turn off the heat, and proceed to the cooling stage.
  • Now it’s time to cool the beer down to 75°f (20-25°c) as quickly as possible.
    1. We love using a wort chiller for this, it can get the beer down to temperature in 20-30 minutes. Otherwise, you can immerse the brew pot in an ice bath or wait it out. The longer it takes, the greater the risk of infection

Fermentation -> Turning the wort into beer

  • After the boil is done it is time to be extra careful in regard to sanitation. We recommend using a no-rinse sanitizer called Starsan. Mix ¼ tsp of it with water in a 500ml spray bottle. Before we touch any part of the beer we spray it with Starsan.
  • Transfer the cooled wort into your fermenting pail or carboy. Run it though a strainer to catch any hop or grain residue.
    1. It is also an important time to take a hydrometer reading. It should be around 1.089 give or take a few points.
      1. If it is a lot lower don’t panic, it can be difficult to reach the desired gravity on beers like this. Our first attempt ended up at 1.070 – the beer turned out fantastic though! Second attempt we were bang on.
  • Your choice of fermentation vessel is important. During primary fermentation, it will bubble up quite a bit, you want to be sure there is airspace for it to work away. Otherwise the pressure of it will push out the airlock.
  • Make sure the wort has been cooled to at least 25c!!! Adding yeast at a higher temperature will likely kill it.
  • Once the beer is in the fermenter, pour in BOTH packages of Cali Ale.
  • Put the bung and airlock in the hole (make sure there is water filled up to the line in the airlock). If using a pail, make sure the lid is sealed tight. Put the pail in a room that is in the range of 18-21°c.
  • After 10 days have passed, take a hydrometer reading. It should be somewhere between 1.011-1.017.
  • Lately, we have been of the opinion that secondary is an unnecessary step. Unless you are kegging, we recommend proceeding to the bottling stage. Clarification can occur in the bottle rather than in a carboy, and the risk of oxidization is greatly reduced.

Bottling -> We’re getting close to Beer Time now.

  • Rack the now fermented beer into a bucket.
  • At the same time, mix the priming sugar with 300ml of boiling water and add to the beer. Stir it in VERY gently.
    1. Make sure to check out a priming calculator to verify the correct amount of sugar. Too much sugar and your beer will end up foamy, or even start blowing the caps off! Too little and the beer won’t be fully carbonated.
  • Rack the beer into your bottles or growlers. Then, let them sit for 2-3 weeks at room temperature. Chill and enjoy!

    A couple of fun new ingredients are rolling into the store, and we thought it would be a good time to make some SMaSH’es. For those unfamiliar, a SMaSH beer refers to a Single Malt and Single Hop. Basically, it’s a way to focus in on flavours of a specific set of ingredients. Most beers are made of multiple grains and hops leading to a delicious combination, but in this case, we want to see what our new malts and hops taste like.

    HAZE | Citra Pale Ale Recipe

    by Connor Creighton June 19, 2021 8 min read

    We LOVE hazy IPAs here at KJ, and we’re not alone. More and more breweries are making super juicy, hop forward beers. Hell, we have 3-4 recipes that are all like that. One thing all of these delicious hazy beers have in common is their high ABV. They tend to range from 6.5-8.5%, but sometimes you simply don’t want a beer with that much booze in it. Enter HAZE, designed and brewed by our very own Jeremy Morris. HAZE has the same super juicy, hop forward notes of NEIPAs but in a sessionable package. Registering in at 5.3%, it is just that bit lighter from its bigger hazy brothers.
