cute vid, looks like cutting edge graphics for the time (seriously). Although now I have to remember what that music is! Cr4p, I'm going to be perturbed all day.

wow, that was awesome. Looked like a decoction mash if you ask me, not that I know too much about it.

I also thought it was awesome that they took a candle to the fermentor to show that there is no oxygen in the air around it.

They did open fermentors then too. Kind of cool considering that is coming back now.

Nice video, thanks for sharing.

That is fraggin awesome!!!

Excellent video, thanks!
Looks like a step mash via decoction. (Maischpfanne=mash boiler; maischbottich=mash tub). Then aerate and partially cool the hot wort in a wide pan, then cool from about 108F to 33F in one minute! What's interesting is the fermentation temp which is 43-48F.
Any lager brewers here ferment that low?

The wide pan is a coolship.

I like their heat exchanger/aerator. This makes me think one could retrofit one of those little decorative fountains for a similar purpose on a homebrew scale.


I also like how they use the candle to demonstrate CO2 production.

Great find. Figure the coils in the primary fermentation vessel were cooling loop?

 

[Mike M]

Very cool. Prost

 

[Rushis]

Awesome video. Love the cooling method, hot wort dripping over a cooling coil. It's interesting to compare the average homebrew santitation practices (chemical sanitizers, closed vessels, etc.) to what is presented in the video.

I wonder how they pumped the hot wort up three stories... that'ld be one helluva a pump.

They could have foregone the music and given a play by play. Course then I'd really have been screwed as I don't speak German. Unless you count bratwurst, pilsner or sauerkraut.....

Mendelssohn A Midsummer Night's Dream.

<sniff> Best foreign film I ever saw...

Kind of appropriate.......

Mendelssohn A Midsummer Night's Dream.

HA! -ding- thanks. (All I can ever remember when I hear it, is that it is NOT Scheherezade)

Where's the beer fairy>?

I have seen this before and liked it a lot. It does give a nice glimpse into early 20th century brewing technology.

What's interesting is the fermentation temp which is 43-48F.Any lager brewers here ferment that low?

Many a starting to move away from this but fermenting at 7-8 C (44-46F) is still common practice in most German breweries. This is what's considered cold fermentation. Warm fermentation is between 50 and 54F.

That's interesting. I would guess many homebrewers trying a lager
for the first time are disappointed because they don't go low enough.
After posting that though I heard Jamil talking on his show and he
does it at 44.

Fermenting lagers in the mid to upper 40s is a good way to make a great lager. Especially bocks benefit from a lower fermentation temps since the yeast won't develop as many higher alcohols. But if you ferment that low you have to make sure that you don't end up with a sluggish fermentation towards the end which can leave too much residual fermentable sugar in your beer.

I used to ferment most of my lagers around 10 C (50 F), I'm now moving towards 7-8 C (44-46F). At some point I'll have to make a side-by-side to see how much of a flavor difference there is.

That video was fricken awesome. Thanks!

What's up with the candle around 8:45? It looks like he pours wax in to the beer.

He is using the candle to demonstrate the CO2 production. No oxygen->candle goes out.
