D Day 2

Here it is, the double decoction Dunkel. (was originally meant to be triple but fuuuuuuuck that).

We made a video montage, thanks to my brother Andre for filming it, and thanks to Dan and Jared for helping out. It was meant to be an educational video but I didn't plan enough so it is just a montage, but I still like it and I hope you do too!

Here are the recipes:

For the Sauerkraut I used this recipe found here.

The beer we made was a Munich Dunkel Kellerbier, adapted from a recipe by Michael Dawson from Brewing TV: episode 34. I've said it before, but if you haven't already watched all of the old MD and Jake Keeler Brewing TV episodes then what the hell are you doing reading this GO AND WATCH THEM!

Here is my adapted recipe, pretty similar except I started at protein rest, decocted to saccharification rest then attempted to decoct to mash out...

60g Carafa III

30g Hallertau Mittelfruh @ First Wort Hopping (FWH)

Mash in at Protein rest with 22L @ 55°C.

Decoct 9L of thick mash and then return to main mash, raising temperature to 64°C

Saccharification rest.

Decoct a further 4.5L of thick mash then return to main mash, raising temperature to 70°C.

Batch sparge with 18L @ 77°C.

Oh also, this is my first lager ever! Although I'm not actually lagering it at all...

More to come, stay tuned!

D Day 1

Decoction mashing isn't a walk in the park.

For anyone who doesn't know, decoction mashing is an old method of conducting a step infusion mash without using hot water to reach each step. Instead, you infuse at one temperature and then take a portion of the thick mash, bring it to the boil, and then add it back to the thin mash, raising the temperature to the next step. This method was used in parts of Europe, namely Germany and Czech Republic, in the past when the malt wasn't as well modified as modern malt and wood was used for mash tun construction (although I'm unsure of the exact details). Some brewers still use this style, saying that the boiling of the grain caramelises some of the sugars, adding flavour and colour (or maybe it's just because they are absolutely insane). Also, I'm pretty sure that some German guy back in the 1700's said something like:

"Ha! Dekoktion Maischverfahren ist ein Spaziergang im Park!"

Well let me tell you 'mr nobody', decoction mashing IS NOT a walk in the park. It is hot, stressful and long. You dirty bastard.

Not that I didn't know this, trust me, I had a fair idea that this might be a long brew day. I had my book out, I decided to give all the math a go. I jotted down all my planned gravities and volumes, not very well, but I tried to not rely on a computer, I wanted to connect with the tradition of a decoction mash. Little did I know that all of this was going to be completely useless against the beast that is decoction mashing, and the second time I was hastily pouring boiling water into the mash tun to bring the temperature up, this really hit home.

So, if you read my last post, this is the first beer out of two that i am brewing for my German Sausage Party or: Deutsch Wurst Partei.

Here is the "planned" recipe:

0---------------------------------------------------------------------------------------------------0

RAUCHIG

German Smoked Ale

Malt:

3kg - Weyermann Smoked Malt

2kg - Munich Malt

200g - Chocolate Malt

200g - Flaked Wheat

Hops:

30g - Hallertau Mittelfruh @ 45mins

30g - Hallertau Mittelfruh @ 15mins

Yeast:

Wyeast 1007 German Ale

Mash schedule:

Mash in 22L @ 50°C for 15 minutes: protein rest.

Draw 9L of thick mash out of the tun, put it on heat and bring to the boil, then add back to the tun, this will bring the mash to it's next step, 63°C: saccharification rest, sit for 45 minutes.

Batch sparge with 18L of water at near boiling.

Get 20L of wort at ~1.060

So it seems fine, right? A nice dark, hoppy smoked ale with a good amount of Munich to add some body and sweetness, some chocolate malt for colour and a toasty bite, some flaked wheat for a nice creamy head, and all decocted to add some dark toffee and really bring out the malt.

Here it goes.

Had my strike water on the heat, want to just overshoot my first rest temperature of 50°C. When it looked hot enough I poured it into my mash tun and then set everything else up while I waited for it to cool.

Overshot quite a lot, more than I had planned, hit about 70°C... It's alright, it will cool by the time I need it.

I've started milling my grain a little finer than I usually do, I think I was having some issues with efficiency because I didn't have it fine enough, what do you think? Too fine?

The new grind seems to work really well, I don't think the husks are too mashed up. Speaking of mash, how's the water going?

68°C.

Don't worry, I knew it wasn't going to cool that quickly, I was just being hopeful. Time to add some cool water... Added some cool water, waited a bit longer, and eventually said "fuck it! 55°C is good enough!"

Stop judging me, Fritz.

Mashed in, first time ever doing it at this low a temperature, definitely looks different.

I then waited 15 minutes to let the enzymes do their thing. Decoction time.

I pulled the first 9 litres of thick mash out. There is only 5.4kg of grain in this recipe, I'm pretty sure that 9 litres of the thick mash is all of the grain.

No worries, I boiled it.

It feels so wrong, but so right at the same time.

I boiled it for about 10 minutes and started to put it back into the main mash, I eventually just poured the whole lot in.

It didn't reach the target temperature of 63°C, instead it only just got to 58°C.

Fuck. This is where I start stressing. Then it hits me: ANOTHER DECOCTION! THAT'S WHAT THEY ARE FOR RIGHT?! YES! YES!

I take only about 5 litres of the mash this time, because of the smaller temperature increase.

After boiling it again for 10 minutes, I just dumped the whole thing back into the mash.

61°C.

I just sit down and stare straight ahead.

No, no I didn't just sit there, I boiled the kettle and poured it into the mash tun. Twice.

62°C.

This is when all felt useless. Time to have a beer.

As I'm sitting there, enjoying the last smoke beer I made, with it's delicious smoked cheese taste, I have an idea.

I can fucking decoct it... AGAIN!

"WHAT NO OSCAR THAT'S FUCKING MENTAL!" - Fritz

Yeah? Well I did it anyway.

It worked. I just got above 63°C.

I waited for 45 minutes while the low temperature mash took place, little did I know more trouble was just around the bend...

Stuck sparge.

Because I had put more water into the mash that I needed, the pressure on the grain bed was quite high, and this caused it to compact down, blocking liquid from getting through. It would have been bad, but I just poured some of my heated sparge water in, stirred it up and kept going. I was not in the mood for any more shit. It worked, but the remnants looked like a post apocalyptic wasteland...

Well, time for the boil. But first, another beer.

This is HOLY MALT. I made a blog post about the brew day recently, and this is now one of the last bottles. You know what that means. It is awesome.

It almost looks like a black IPA here, but in the right light, it glows like a red sunset. Sticky burnt toffee, tongue searing bitterness, pine needles, tropical fruit, biscuity bread crust, this beer rules.

How's the boil going?

Ahh my favourite part, the velvety protein foam on top, swirling elegantly with every small stir. Everything seems so calm now that I have the sweet wort in my grasp and everything is under control.

The boil went without a hitch, it felt so good.

I no-chilled the beer, but not before I collected 2.5L of wort from the kettle into my new 3L Erlenmeyer Borosilicate flask! Real wort starter! I had a small extract starter in the flask before, but I decided to give them some more sugar and keep them healthy, that's why I split the two.

Anyway, until the next decoction.

Cheers!

EDIT: Today after it had cooled over night, the gravity came in at 1.052, but I got 23L instead of the planned 20. Pretty close, even with all the hiccups. Pitched the yeast and a few hours later, activity!

Build up to the biggest brew day of my life.

In the next couple of weeks, i am going to undertake some crazy, crazy brewing things.

Here's the plan:

I'm going to host a German sausage fest at my house, we are going to source some awesome kransky and bratwurst, probably smoke them and eat them with home made sauerkraut. To go along with these, i am going to make 2 beers, a Rauch-Ale and a Munich Dunkel Kellerbier, inspired by this recipe from the golden days of Brewing TV.

Both beers i am going to use the decoction method to brew, the Rauch-Ale will be single decoction with a mash out and the Dunkel will be TRIPLE DECOCTION.

Not only am i completely terrified of decoctions, i am completely terrified of decoctions.

The other thing is that i will be serving them in corny kegs which i am converting to casks. They will be cask conditioned, low carbonation, and served at ambient winter temps.

And lastly, i will be getting my brother, who works as a video technician for Penguin Books to be filming the whole thing, with detailed instructions on how to do everything (including how to make sauerkraut!).

So stay tuned, this is going to be fun.
