JFYI, I don't cold crash my lagers:
- I've heard Jamil Zainasheff say more than once that lager yeasts can generate off flavours if you cool them too quickly - I think he suggests one degree (and I assume that's degrees F!) per day!!! I'm too impatient to wait that long!

Right.. So I might dump my yeast out of the fermenter and lower it one degree a day until it's down to 4 and then leave it at that for a few days just to get the last bit of yeast out.

My Czech Dark Lager recipe is here and I'm very pleased with it

Excellent.. Cheers, I'll give that a try at some point.

if you watch the series of videos on YouTube that The Malt Miller did with Budvar you'll find Budvar don't do a diacetyl rest, they just keep it at 10⁰C or so.

I've watched those.. Interesting series, especially the poring of the beer.. My those taps are expansive Not sure I could go down the hassle of the decoction though.

Apologies to @Alastair70 for hijacking your thread.

Haha, yeah I thought that too - holy moly, HOW MUCH???!!!

Not sure I could go down the hassle of the decoction though.

I've done it once, earlier this year - I think it's worth doing even if only once just so you know rather than going on what you've read and heard

Apologies to @Alastair70 for hijacking your thread.

Haha - yeah, sorry dude (but I know you're just as nerdy and obsessive over this stuff so I figure you'll be ok with it )

The ferm zone is full, Munich Dunkel on the left, Czech Pils on the right.
And to think I once said “I didn’t start brewing beer so I could make fecking lager”.

A few years ago a remember saying to this guy who used to come to homebrew club ( he was into Euro beers and lager) that I would never brew lager. Now I would say my preference is definitely towards Euro hopped beers more than American hopped beers and definitely loving quality lager.

@SMP Brewery @matt76 Enjoying the lager chat, that’s what brewday threads are all about.
Czech Pils update, 2 1/2 weeks in and it’s most of the way there. You could see the steady stream of CO2 bubbles from fermentation in the trial jar, particularly as it warmed up, which was quite cool.

First brewday of 2024. It's always good to get your lagers going early so it's a Munich Helles today.

Soundtrack: Tool, Porcupine Tree, Opeth

Water - slightly bitter profile
Ca 52, Mg 16, Cl 80, SO4 142

Fermentables
4.25kg Weyermann Bohemian Pilsner
350g Weyermann Munich II
100g Weyermann Melanoidin malt

Step Mash
30min - 62C
30min - 70C
10min - 75C

Hops
17g Mandarina Bavaria 8.5%AA - 60min (16IBU)
8g Saaz lupomax 8.4%AA - 15min (4IBU)

1/2 tab Protoflac - 15min

Yeast
WLP860 Munich Helles

Vitals
OG 1.054, EBC 9, IBU 20

I was heading for a significant overshoot on OG, so topped up the kettle with 1.5L water at the end of the boil. 22L in the fermenter at 1.054, it'll sit at 9C for 4 weeks before kegging.
Got the Czech Pils kegged and on gas while brewing, so it's been a productive day.

 

[matt76]

How long do you think you'll hold out before tapping the Czech Pils?

Helles looks nice and clear already

Out of interest, once you're done chilling the wort, do you let the crud settle out or just transfer everything over to the FV?

 

[Alastair70]

Im doing dry January, so 1st Feb is looking likely
I transfer everything then cold crash before kegging. The pils has had a week at 2C in FV. I was transferring very clear beer through a Bumper Inline filter.

 

[Alastair70]

Munich Dunkel is done, bang on predicted 1.014 for an ABV of 5.3%. I’m not tasting any diacetyl, it’s nice and malty and very well attenuated. Colour might be a bit on the light side, I relied purely on the decoction for that. Overall, I’m very happy.

 

[Alastair70]

The ‘Heavy Bevvie’ got brewed today, it can do its thing while I’m away next week and still have a good 4 weeks or so to condition before the collaborative swap in March. I switched up the Pale Chocolate to full colour to keep BrewFather happy, but looking at the end result it was an unnecessary step. I tweaked the grain bill from the Zamil recipe in Brewing Classic Styles, the 20%+ crystal malt scared me a bit, and stuck with a water profile that should help balance any added sweetness.

22L in FV at 1.046, a slight overshoot. I’ll need to up my efficiency in BrewFather.

 

[Alastair70]

Well that took its time. The swig from the trial jar tastes great. If it lives up to the early promise I’ll use Top again, but I’ll do a vitality starter first.

 

[Alastair70]

Had a busy couple of months, but back at it today. Brewed a 19L batch of Bière De Garde, over a month later than planned. Had to switch yeast as the Kölsch yeast I was going to use was end of life. Went with GEB’s own brand chico and will ferment cool to keep it clean.

Wow that’s beautifully clear wort - hat’s off to you, sir

It’s all down to the protflac and letting the sample settle for 10 minutes
