Canadian Bacon Ya'll

Homemade peameal (sans meal), ready for frying
So this post has nothing at all to do with brewing, or even movies from the 1990's, but rather has to do with...bacon. Specifically, the making of the king of all bacons - peameal bacon (aka Canadian bacon, aka back bacon). My Canadian readers, depending on exactly where in Canada they live, will be well aware of this wondrous meat by at least one of three names - in the west it typically goes by the name of "back bacon", although some stores sell it as "Canadian bacon". Out east it is most often sold under the name peameal bacon - so-named as it was historically sold rolled in white bean meal (today corn meal is the norm). Regardless of which name you call it by, it is a wonderful thing - its the bacon you pull out for special events like Mothers Day brunch, or Christmas breakfast, or because you feel like spoiling yourself.

My international readers probably have no idea what I'm talking about - this isn't your classical salted and smoked pork-belly bacon, nor is it the product sold in some US states as "Canadian bacon" - this is a much more refined piece of cured meat; a cross between a corned beef, ham, and classical bacon. It is a brined pork loin, which after brining is typically rolled in either corn meal or white pea meal before cooking. You can slice it thin and serve it with breakfast, or smoke it to make a great sandwich meat, or even slice it thick and fry (or BBQ) it and eat it on a bun. And as with beer, it is easy to make at home, and when "home brewed", yields a product superior to that sold in most stores.

A (sort-of) update on Brett trois

Some of my readers will be aware that I and several others have done some genetic analyses that suggest that WLP644 (Brett trois) may in actuality be a Sachharomyces. For those not familiar with this issue, or who need a refresher, my post covering both my work and some of the work done by others can be found here: Brett Trois - A riddle, wrapped in a mystery, inside an enigma.

Chris White talked briefly about the "controversy" surrounding the true identity of Brettanomyces trois in a Cheers Charlotte podcast a few days ago (time stamp 28:45 to 30:05). He didn't give away the punchline, saying "it is too early to tell" and that "we have seen some signs it is Saccharomyces". He went on to state that the results he has seen are mixed and that it is not yet clear. Apparently, they are waiting for the whole genome sequence to determine what it is, and if it is a hybrid. But it sounds to me like he is leaning towards a Saccharomyces identification as well.

Ambrosio, The Fallen Monk

This post is the ultimate post (minus the inevitable tasting notes & updates which will follow over the upcoming months and years) in my Brewing Vintage Beers Series. Today's beer is  a Belgian Septuppel, which is the closest number I could come up with that matches the normal Belgian beer-naming scheme*. What is this oddity? It is a strong Belgian Dark Strong (aka a Quad) fermented to at least 20% ABV, and potentially 2-3% beyond that.

* An analysis of over 80 Belgian Enkels, Dubbels, Tripels and Quads reveals that commercial brew "names" follow the formula %vol = [4.0296 * 1.3559%vol]. I.E. a 20% beer would be:
20% = [4.0296 * 1.3559Bel], where Bel = 1/2/3/etc (Enkel, Dubbl, Tripel, etc)

My new eHLT in action
(in my under-construction video
studio - AKA laundry room)
Why would anyone do such a thing? For me, there is two reasons. The minor reason being that while I've brewed mead's that pushed up close to 20%, I've never hit or exceeded this strength. Its a completely arbitrary, and yet almost mystical threshold. What lies beyond that I do not know - perhaps beer nirvana, more likely a really bad hangover, but either way I want to see what is one the other side.

The main reason is a bit different - December 9th, 2016 will mark the 20th anniversary of my first brewday. I though it would be nice to have a beer whose ABV was at least as large as the years leading up to the anniversary. To make sure this happens I have over-designed the beer; assuming it attenuates as I expect I should get a beer at 22-23%, but I suspect I may not get quite that much attenuation, and as such, I've hedged my bet. I'm brewing it now since I'm certain its going to emerge from the primary as a fusel, ester and phenolic mess, but with roughly 20 months of aging ahead of it, it should have turned into something really nice on time for 12/9/2016.

To get to that mystical 20% I'm using every trick in the fermenting high gravity beer playbook. Multiple yeast additions, holding back the ~20% of fermentables that are sugar until a day or two into primary ferment, multiple yeast additions, multiple oxygenations, and I'm pitching a shit-tonne of yeast (roughly 5 million/ml/oP) thanks to my use of my last brews yeast cake. And the ace in my sleeve - a backup 2L starter of White Labs super high gravity yeast. I'm hoping to not need that bad-boy, but if I do he's ready to go.

41 L of wort boiling on the range.
Brew-day itself was a bit of a mix-up; I recently bought an electric HLT from one of the co-owners of Forked River Brewing (I guess you don't need to homebrew when you have a real brewery), so I was able to do my mash indoors, with the plan of venturing outside into the -25C weather for the boil. Turns out propane valves freeze at -25C - even if the propane itself is at room temperature, but my wonderful wife was kind enough to clear out the kitchen for the day so it was a full-volume boil on the electric range too get this beer down to gravity - adding an hour to what was already supposed to be a 3 hour boil. But in the end I exceeded my numbers slightly by 4 points), and everything looks like it went well, so now onto the ferment.

The recipe, brew-day notes and other details are included below the fold, but I thought I'd spare a word on what is now the second really odd name I gave to a beer in the past 2 weeks. These two beers are deeply connected - with "Matilda, The Seductress" functioning as a starter for "Ambrosio, The Fallen Monk". These names are not arbitrary - they are drawn from my favourite novel, "The Monk" by Matthew Gregory Lewis (legally available free from the Gutenberg Project). In this novel the young monk Ambrosio is seduced by Matilda - a familiar of the devil - leading Ambrosio down a road of murder, rape, insect, and eventually death at the hands of Satan himself. As with the novel, the beer "Matilda , The Temptress" gives Ambrosio his drive to darkness (namely, a lot of yeast) - and "Ambrosio, The Fallen Monk" somewhat follows the tradition of naming these beers after devils & other dark creatures...

Quick & Simple Invert Sugar

2 kg (~5 lbs) of invert sugar. The one on the right is slightly less
caramelized due to better temperature control during inversion
In some of my previous posts I've covered the making of Belgian Candi Sugar (Posts 1, 2), but this isn't the only hard-to-find brewing sugar out there. For my upcoming big beer I need a healthy dose (2 kg) of invert sugar - something which around here you cannot get in anything less than industrial amounts (a hundred kilos minimum order).

Invert sugar is used in a lot of English-style beers; it is simply table sugar (sucrose, a glucose chemically bonded to a fructose) broken down into its constituent glucose and fructose molecules. In theory it is easier for yeast to ferment this sugar, hence why it is popular in high-gravity brewing.

Several of my readers and youtube viewers (and myself) have reported issues with sugar crystallizing, which if you're lucky makes a hard-crack sugar ugly, but if it gets too bad can turn your sugar into an unmanageable - and insoluble (which is bad for brewing) mess. I've been working on this issue and have found a solution - the details are included in this post, and can be applied to both Belgian candi sugars as well as to invert sugar.

And as with candi sugar, don't forget that this can be quite dangerous - you are working with a sticky liquid well above the boiling point of water. Wear long-sleeved shirts and pants, cover your feet, and be as careful as you can be.

So how do we make it - its easy, but as always the details are found below the fold.

Matilda, The Seductress

The Temptation of the Idler
Albrecht Dürer, 1498
This is the penultimate post (minus the inevitable tasting notes) of my Brewing Vintage Beers Series. Today's beer is  a Belgian Enkel, also known as a Patersbier. This is a style of beer that I wish was much more common - it has all the flavour and complexity of a double or triple, but comes in at less than 5% ABV and thus is quite sessionable. It solves all of the problems of dubbel and tripels; you can imbibe in pint after pint of an Enkel without finding yourself hugging the floor as the room spins around you.

This beer is obviously not a high-gravity beer, so why is it part of the vintage-beer series? The answer is that this isn't just any old beer - it is also a massive stater for one hell of a big beer I'll be brewing (and posting about) in two weeks time, and its also been scaled up to provide a few extra litres of wort to test-ferment a dozen wild yeasts I've isolated over the past year. This is truly a beer with many faces!

To make this beer a good "starter" for producing yeast I am taking the rather unusual route of adding yeast nutrient to what is a beer that wouldn't normally require it - but keep in mind, our goal isn't simply a good beer, but its also healthy yeast at the end of the ferment. Yeast nutrient plus a strong oxygenation will fulfill that goal.

Some may be wondering about the odd name for this beer. I don't want to give too much away, but it is related to one of my favourite novels and also to the name of the strong/vintage beer this beer's yeast cake will be re-pitched into.

Brewing long-aging beers - fermenting high-gravity beers

As promised last week, this is the fourth instalment in my "Brewing Vintage Beers" series. In this post I'm going to cover some of the methods that homebrewers can use to ferment beers that push - or even exceed - the rated alcohol tolerances of the yeasts being used. Experienced brewers will likely see nothing new here, but I've tried to include a bit of the science behind what the different methods do, so that my readers have a better idea of why these things work and are often necessary.

There are a number of things you can do to get full attenuation when brewing high-gravity ales, namely:
  1. Yeast selection
  2. Pitch rates
  3. Late/repeated oxygenation
  4. Late sugar additions
  5. Late yeast additions
  6. Managing the fermentation
  7. What if the batch doesn't ferment completely?
