How about now?
Looks great!, 120 is bad enough 240 can really knock you on your a** so better safe then sorry. Especially by a pool. :cross:
I predict we will see pictures of a water test soon

Water test Tuesday.... Assistant Brewer is charging his video camera battery tonight....I've never put anything on YouTube before, but if the video is worthwhile I'll see what I can do....standby...
It's here! The box is in really good shape (minor scar). So hopefully no damage. Now on to the un-boxing.
Today we will be brewing our first batch on the 20L - not only our first batch on the 20L, but our first batch ever. I hope to capture much of today's activities on video. Hopefully Assistant Brewer Larry remembered to charge the battery of his video recorder last night.
For this first brew we have chosen a simple recipe. Almost a SMASH (single malt and single hops), but not quite. We will be using two malts.
- 4kg 2-row pale American malt
- .300 10 degree crystal malt
- One package of Willamette hops (1 oz/28.35mg)
- One package of Wyeast 1056 American Ale yeast
Our mash schedule is probably more extensive that it needs to be. Everything I've read indicates that with today's highly-modified malts our extensive mash schedule is not necessary, but it shouldn't hurt, and I want to give this first brew every opportunity to succeed. The system is automated; so the complex mash schedule does not complicate our brew day. With today's highly-modified malts some of the comments I have in parenthesis after each mash step may not be pertinent, but they explain my reasoning.
Mash-in: 38C
1) Protein Rest 1: 30 min @ 50C (to develop yeast nutrients)
2) Protein Rest 2: 15 min @ 60C (Improve clarity and foam potential)
3) Beta rest. Saccharification: 20 min @ 66C (for light-bodied beer)
4) Alpha rest. Dextrinization: 0 min at 76 (for heavy-bodied beer)
5) Mash out: 10 min at 76C
Boil: 75 min at 100C
Willamette hops added at 60 min
Irish moss (1 oz/ 28.35mg) and additional 4mg gypsum (see below) added at 15 min
We're using our tap water, which is very, very soft and with very high mineral content (Texas version of Burton) and high pH. Out of the tap the pH was off the scale of my litmus paper on the high side - digital pH meter read 8.4. Yesterday we prepared the water with an initial addition of 4mg of gypsum. This brought the hardness up to between 50 and 100 ppm (litmus paper is not too precise) and the pH down somewhat. We then added 7ml of 85% phosphoric acid (food grade) and the pH dropped to just above our target of 5.8. It was at 6.1. This morning before the brew I will check the pH and hardness again and touch up, with a goal of beginning the mash with 5.8 pH and hardness >50 and <100 (don't want the water too hard during the mash). Near the end of the mash additional gypsum will be added to get the hardness up to ~150 ppm.
I have not made a starter. My plan is make a starter from the wort brewed today. This will mean that pitching yeast will be delayed a bit.
Wish us luck.
change the boil to 102
We had a near catastrophe yesterday
... and the top sieves and the grain under them suddenly rose, and before I could react, were 1/8" above the top of the malt pipe and grain was overflowing into the outer compartment...
I screwed up and added the Irish moss during the last few minutes of the mash instead of during the boil. Did not realize this until the system beeped during the last few minutes of the boil to remind me to add the Irish moss; so we added another 1g of Irish moss at that time.
Did you add the water to the correct marking on the center rod and then add the malt pipe? I don't see how the coils didn't stay covered?
Also, were the pumps still running when you started removing the sieve?

Crazy! Any damage to the machine? If you were boiling over those jackets must really work. I never hit above 99 un-jacketed with my temp set at 102

Yeast has now been pitched. Let the fermenting begin!
You're not supposed to touch the metal grill and sieve, just open the nut and get rid of the bar, then lift the pipe to rest on the kettle. When you lift the malt pipe, the sieve and grill will move up too along the centre metal rod. When you then lift the malt pipe away say onto a big bucket to drain, no need to touch the sieve either.

May I assume you are using a hydrometer, not a refractometer? If so, are you allowing the wort to cool to ~70F before taking a reading? and are you correcting for temperature?
Could your hydrometer have gotten bumped and damaged, such that the scale is able to move?
I do a 90 minute boil and my post boil volume is right on but my OG is about 10 -15 points low, in fact today it was exactly the same gravity as the pre-boil gravity!
Obliviousbrew said:If your pre-boil volume and gravity are spot on, and your final volume is spot on there is no way you can miss your final gravity, there has to be some miscalculation in your recipe or if you are using some beer software it´s probably not well adjusted.
Boiling the wort will anly reduce your volume and therefore increase the gravity of your wort it´s impossible to loose sugar during the boil,

Yes, I use a hydrometer and have calibrated it with distiller water. It seems to be fine. All my other readings are normal so I'm investigating other areas in my system. Unfortunately this was not a one time issue, it's been a consistent problem for the last couple of months. I'm thinking maybe my therminator is leaking. I've talked to Blichman and they're helping me with that.
Thanks,

If you're hitting your final volume it doesn't really make sense that your chiller is leaking. To have no change in gravity from pre to post boil means you'd have to leak the same amount you've evaporated in which case your final volume would equal your starting volume. For the sake of being thorough you could try checking your hydrometer in a known sugar solution. Dissolve 10g of sugar in 90g of distilled water and see if it reads 1.040. Don't forget to adjust for whatever temperature your hydrometer is calibrated at.
