Still a rank amateur at the end of the day.

You're always learning new things about brewing when you're a brewer... like remembering important steps throughout the the brewing process. Especially remembering to put the temperature probe in the conditioning fridge when attempting to condition a nice robust Porter.

Dunno what I was thinking on this one, but I ended up with about 15 Liters of 8% Ice Porter. It tastes pretty good... Decided to call it "Titanic Porter" given that there was an enourmous iceberg still floating in it when I decided to keg the bugger.

I also learned how to clean black goop out of my fridge and off the floor:

Nice!

Another thing that I learned was to follow your instincts - remember how things went in your previous brews, and make adjustments to help improve things. The perfect example is the first brew that I made in 2010: a Russian Imperial Stout.

I can remember that when I milled all of my grain together - there were a couple of anomalies. The Roast was in big chunks and the Oats Malt looked like they were almost whole still. So what I did on the brew I did this Sunday was crush the Oats and Roast and Malt all seperately on different mill settings... so first of all I milled the Roasts - 1.2kg all up. I milled this stiff firstly with my normal gap setting, and again with the rollers touching. This process turned all the roasted grains into dust.

Then, I adjusted the gap to halfway between where I normally have it from where they were touching. Then I milled my 2.5kg of Oat Malt. This worked a treat - the insides got ripped out and the huskes were still largely intact. This was a great idea.

Then after all that - I milled the crystals and base malt at my regular setting:

12 kilos of malt all up to go into a 20L batch of brew...

Now here's another learning curve: I planned to use a liqour grist ratio of 3:1 which meant I would have needed 36 Liters of strike water - this was more than my bloody boil volume! I didn't think that through fully at the time - because last time I used 2.2:1 which is why I had such great efficiency last time. I should have gone the same way and things would have been the same, but because I had more mash volume - my sparge depth had changed (it was deeper) meaning I couldn't effectively rinse the grains without diluting the sweet wort below the sparge water. Basically this means I went from 81% efficiency to 75% efficiency meaning I didn't hit my target of 1.107. I only got 1.100... bummer.

Heres a pic of me recirculating 45 Liters of mash:

And how the sparge works in my brewery:

I know another brewer who is about to get one of the pictured magnetic drive pumps... Happy Brewing!!!

Mate, first you freeze my Bourbon Porter then you freeze the entire batch of Porter we brewed??? lol

Also, crazy write up about the RIS, that looks like an insane brew day! Is that the RIS I tried? It sure was tasty!!

Yeah - it was... it's more an Imperial Oat Stout (but I didn't wanna get all anal on it...)

Cant say I picked up an oat character out of it, but I guess hidden behind everything else it would be quite hard!

Where did you get said pump, and how much?
Comment by JoKing on August 5, 2010 at 8:14am
We got 20 of them over from China early last year and hocked them off for aroud $150 each. Tempercon have them availableon trademe for a bit more - but they are worth every cent.

you could a march for that sort of money though - if anyones keen I was thinking of bringing in a couple.
Comment by Martin Bridges on August 5, 2010 at 8:58am
How much do you reckon for a March mate?
Comment by Greig McGill on August 5, 2010 at 9:19am
What's so great about a March compared to that one Joseph posted? It looks pretty cool!
