I wouldn't call that linear fit to the data "statistically significant". There is a heck of a lot of scatter of the data relative to that line. I wonder what the conclusion would be if a different function were fit - perhaps it would conclude that moderate sulfate levels are beneficial. Of...

OK. Here goes… This is the parts list. Yes, there are a lot of parts. But everything is just thread together parts except for the soldering as has already been discussed. So, just solder on the ferrule and the 2 tank post & dip tube nipples and thread everything together. I used...

Kshuler, I have not yet test driven this contraption. I'll put together a parts list sometime this week when I get a chance. I'm guessing that heavy trub might be a bit of a challenge - if your trub clogged a 1.5" butterfly valve, I'd guess that it'd be difficult to push out of the dip tube...

That's exactly what I did - attach it to the conical and fill with water. Letting it sit for a while like Artifishal did is a good idea. I let it sit for just a few hours and called it good enough. I'm glad this worked out for you! Cheers, Pliny

Artifishal, I tried the hole saw approach but didn't like the results. I preferred a slightly undersized hole drilled with a step bit. It was a lot "cleaner" of a cut. I ended up pulling the ferrule through the undersized hole to create a dimple, but simply butting the ferrule to the lid...

OK - here are a few picture that show how I did this... Pic #1 is just drilling holes in a lid - mark your layout and drill away. Since I want a ferrule and two posts (ala maierhof's yeast harvester rig), I have three holes to drill. I used a 1.5" TC ferrule so I ended up drilling a 1-3/8"...

kshuler, I'll be posting some pictures this weekend that will show how I soldered the ferrule to the lid. I think the key is to heat slowly and to focus the heat on the ferrule - not the lid. Since the lid is so thin, it will overheat and burn off the flux before the ferrule gets warm enough to...

maierhof, Nicely done! Looks like that worked out pretty good for you - a nice clean jar of yeast for your next brew session without a lot of hassle. Cheers!

Artifishal, Your lid removal system is the exact same way I remove my lids. Those suckers are tight! I don't recall cranking them down that hard, but it sure gets stuck. The band wrench (or whatever that thing is called) sure comes in handy. I just brewed a Pliny the Elder clone. I attached a...

OK. Here you go. These pieces are what I use to do my pressure transfers. The first pic is the parts all broken down in to the individual components. A1 is a digital pressure gauge that I use to monitor the CO2 pressure going in to the conical. I don't trust the accuracy of the usual gauge...

WoodlandBrew, How does adding only part of the DME prior to the beginning of the boil effect hop utilization? If I'm brewing an IPA and add only half my DME in the beginning and half at the end, will the hop utilization be the same as adding all the DME up front. I'm looking to brew an all...

danimalt, Thanks for the advice. I guess I didn't make myself clear - I'm brewing this beer as an extract batch. The mashing has already been done. The maltster has already set a base mineral profile when they made the extract. The pH of the mash that preceded the making of the extract was...

All, My brew partner and I are going to brew an extract beer - a Pliny the Elder clone. I understand that the maltster has already taken care of pH and such so I don't have to worry about that, but what would you recommend for an addition of gypsum (or calcium chloride)? My plan is to use soft...

Looks decent to me. Your pH is in the ballpark according to the calculator. That's the most important aspect. And you've targeted a reasonable sulfate level for a bitter beer. There's nothing "wrong" with what you've got there. If you like the beer that you get, then what you've come up with is...

It isn't necessarily right because it's simply a recipe. Sometimes I'll look at a recipe and think that there's way too much dill for my tastes (pretty much any dill besides in a pickle is too much for me) so I'll cut back on it. It's the same thing here. Some folks like very high sulfate for...

My apologies!!!! I did find an error in my original post. Ok. Let me try again. ((OG-1)x1000xVpost-(SG-1)x1000xVpre)/DMEppg = weight of DME needed So, going back to your problem, OG = 1.082 Vpost = 5 SG = 1.051 Vpre = 3.5 DMEppg = 42 ((1.082-1)x1000x5-(1.051-1)x1000x3.5)/42=5.5 lbs If your...

Well, something isn't right here. I suspect that your post boil gravity measurement is incorrect. Pre-boil, you had (1.051-1)x1000x3.5 or 178.5 points of sugar. To that you added (assuming 42 ppg for you 5 pounds of DME) 42x5 or 210 points for a total of 388.5 points of sugar. Post-boil, you...

JB/Arti, I actually did this two different ways: 1) I drilled a hole in the lid using a step bit. I drilled the hole the same size as the internal diameter of the ferrule. I then simply butted the ferrule to the hole and soldered. 2) I drilled the same size hole as in #1, but then pushed the...

Oh - I missed that you were adding water to top up to 5 gallons. In the end though, you still just count sugar. Adding water is just adding zero sugar. Do you have all of your measurements - pre-boil gravity and volume and your post-boil gravity and volume? If you give that, then we can work...

I'm with bja. The only comment I would provide is to fill your keg through the beer out port. I fill my keg to the very top with sanitizer. Then I hook up CO2 and a picnic tap and empty the keg. Now I have a keg full of CO2. Disconnect the CO2 in line. Next, I keep the keg sealed. I pull the...
