Yeast and Fermentation / Re: stuff I'm finding under the microscope

Here is a crude drawing of the thing with a yeast cell in comparison:

Sorry Kai, but it totally cracked me up that you labeled that sketch as "Thing."  May I suggest that it henceforth be known as the "unidentified flagellate organism."  Wait - that's UFO...   Kai, there's a UFO in your beer!  Run while you still can!  ;)

FWIW, A good manifold or braid design will work fine with a pump, too.

Equipment and Software / Re: Three Tier Stand - Design Considerations
« on: January 12, 2010, 07:36:38 PM »
If you're set on a three-tier system, go for it.  However, have you considered a two-tier system with a pump?  That would let you keep the overall height lower.  You'd be able to fly sparge if you want, and you can use the pump for a variety of other uses - like recirculating while chilling, or pumping to your fermenter.  I'd suggest that you try building a a mock-up of your system to try the height dimensions you're thinking of.  You could do that with a ladder, table, saw horses, or whatever is handy.  I did a brew session with a mock-up of the system I'd been thinking about to see how it worked out.  It was very helpful to actually brew on the mock-up because I found some things I'd like to change, add, and delete from my design.

I've been working out the details for converting a salvaged factory cart to a brew cart, and I've settled on a single-level system.  I batch sparge, so I'll only need one pump -  which I recently got as a holiday gift.  The cart will have two burners on one level, and a folding shelf on the end to hold a mash tun.  I might even try to design the shelf so I can tip the mash tun for emptying.  I settled on a single-level system because I won't need to lift very much, or have hot water up high.  I also want to be able to look into the top of any of the brewing vessels without using a ladder, stool, or mirror.

Where's Weazeltoe? He would get a kick out of this.  8)
He was probably driving the train!  ;)

Pimp My System / Re: I give you THE BEAST

I'm working on a brew cart over the winter, and will "borrow" your adjustable-height burner design.  I bet those bins are handy, too!  I presume you do hot CIP with something like PBW or OxyClean?

That manifold is a slick build though.  
Here's the same manifold configured with just a few different parts in my 28-quart Rubbermaid that I use for smaller batches.  It's sort of like having MLT "Legos."  ;)

Shouldn't need to cut a new hole.  As long as you have the two elbows (in the picture above), you could just attach a braid instead of the manifold shown.  Both (manifold or braid) should work equally for batch sparging and leave you about the same amount of deadspace.
+1  The elbows do the job if you establish a good siphon when collecting your wort.  You could also use a piece of flexible tubing run directly through the cooler's drain, or through a drilled stopper something like Mullerbrau did with his:  His isn't a 60-quart, but the idea and the physics are the same.

I also use a CPVC manifold in my 60-quart Igloo, but I think a braid could work, too.  The key is to establish a good siphon when you collect your wort.  Here's a picture of how my manifold is configured.  The manifold has slots cut into the CPVC that rests on the bottom.  I cut them with a hacksaw, and they're about 1/2" apart.

General Homebrew Discussion / Re: what are your goals for 2 ought 10
« on: January 05, 2010, 07:45:28 PM »
In no particular order:
* Work out a practical (for me) way to reuse yeast
* Get better results with lager beers than I did last year - bigger starters should help
* Assemble my brew cart, now that I have most of the components - maybe with natural gas burners
* Score 70 or higher on the BJCP exam (February 13th)
* Be more active in my local homebrewers' club
* Teach a friend to brew

Equipment and Software / Re: Using a pump

In reference to the posted link, why does it say "This is the real deal" when comparing the side inlet vs the center inlet? Does it make a difference other than aesthetics? I would think I could just install an elbow into the center inlet model and till get same effect.

And also, is $130 pretty much the going rate for the March pump?
I don't think the inlet orientation (center vs. side) makes any difference in the pump's performance - it would just affect how you configure it for your system.  The $130 price was the best I found at the time for the 809-HS with a plug and cord.

It might make a nice fermenter.  Maybe you could rig up some way to pump refrigerated water or glycol through the jacket for temperature control.

What kind of pumps are you all using?  I've seen the March 809 recommended.  Any good sources for a nice pump that you know of?
I just got a March 809-HS from "Santa."  One of his elves told me he got it here:

I don't use a grant - I connect the pump to a QD fitting on my mash tun.  I prime the pump with the 1/2" mash tun valve wide open and the valve on the pump outlet mostly closed, and leave it this way during vorlauf.  Then, I gradually open the pump valve until wide open for running off into the boil kettle.

came out good.  angle grinder.  no water just the stale beer that was leeft in it.  still wanna tune up the edges more....or thats what my arm told me after i washed it.   ouch.
A Dremel with a grinding attachment works well for cleaning up the rough edges.

Ingredients / Re: Raspberry beer flavoring extract
« on: January 04, 2010, 02:46:14 PM »
Haven't used it but have always heard to go with real fruit over the xtract. Supposedly the Oregon Fruit puree is the way to go. Add it to the secondary - general rule of thump is 1-2lbs of fruit per gallon.
I've used the Oregon Fruit puree with pleasing results in a Raspberry American Wheat recipe.  I used a whole 49 oz can of puree in a 6 gallon batch.  After the primary calmed down, I racked the beer onto the puree in a carboy for 1 week of secondary.  Be aware that, if you use the fruit puree, the color of the beer will change substantially.  With the raspberry puree, the beer was fairly pinkish in color.  I added some biscuit and honey malt to the recipe, and the beer had a bit of a raspberry pastry flavor - the biscuit and honey malt gave it a hint of pie crust.
