I wouldn't worry too much. These things are probably designed with a lot of margin. Also, if you get to the point where the liquid starts boiling at the hot spots (where the coils touch), the heat transfer coefficient actually goes up with heat flow. At least it does for CO2. I'm pretty sure the...

Thanks to both of you. And as a bonus I learned the good old german word "Hefestripping"! update on my Paulaner Hefeweizen (from a can) 'stripping' attempt: dead as a dodo.

Good to know! Thanks!

Besides the bottle collecting, cleaning, filling and carbonating issues, kegs also make storage so much easier. I built my own small cooling system that can take care of an insulated keg and a fermenter at the same time. No need to use up all that fridge space for bottles.

Thanks, I see, so one of the numbers is measured close to boiling, and the other close to 4C/40F.

Are you sure about the wort densities? The temperature corrections can become pretty large if you measure hot wort. Preboil 1.026, postboil 1.04 means you boiled away 35% of your wort; 0.35 * (12.5 + 3 - 2*) = almost 5 gallon. Does that sound likely? (*): assuming 2 gallon stuck in bag Maybe...

What's that magic factor '1.04' ? Spillage? Samples? Quarts to liters?

Sure, but then you have a lifting table! I'm very much in favor of synergy for your different hobbies. Now, if you don't like motorbikes, then that's a different issue. But a lift table might also come handy for woodworking, restoring furniture, metal work, overhauling your wheel chair, that...

I think I'm going to stick with the Wyeast 3068 'Weihenstephan Hefe'. I like the commercial brew, and I like how my beer turns out. Did I mention that I tested them back to back (ran out of homebrew, and had to buy commercial beer - Weihenstephan was on sale! Coincidence? I don't think so!), and...

Last Saturday I did exactly that experiment, and having the coil closer to the top doesn't really make a difference. The water coming out of the coil turns cold again very soon after moving the coil (it's hot, like the wort, immediately after either moving the coil or stirring the wort), and...

They make motorbike lift tables (scissor lifts, essentially) that might just be the right size for brewing vessels.

Catching up: 4 batches on 5/16 (1.85 lbs) 3 batches on 5/30 (1.39 lbs) 4 batches on 6/14 (1.85 lbs) 419.14 + 5.09 = 424.23 lbs Edit: Yeez, I'm sure drinking a lot of coffee!

Jayjay, really sorry to hear that. I'm a fellow Chicago brewer, albeit with a bit less experience. I brew Weizen and Pilsner. I'm really happy with my Weizen, and I find I have to try and keep the banana flavor down... As I mentioned in Konstantinos thread (also unhappy with his Weizen), all of...

Ok, so maybe it's more than 1%. But I squeezed nowhere near half a gallon out of that bag. If I try to measure the amount of liquid, I will for sure make a mess....:yes: Regarding step mashes: I am doing step mashes, with a bag in a 5 gallon kettle with ~4 inches of headroom, on a 15,000 BTU/hr...

I think (but I might be wrong) by 'stretching' the OP means that he distorted the helical coil slightly in the axial direction. I don't think the actual heating element got stretched (as in, the length of the wire/tubing changed), he just moved one of the windings around a bit.

radwizard, I'm not sure what the number of vessels has to do with using a brew bag or filter. I'm using between three and four vessels typically (I'm trying to do 5 gallon brews with two 5 gallon kettles :smh:, so I need one or two additional small vessels for Vorlauf handling and intermediate...

I can't find what mesh size they are using. Does anybody know? Also, bummer that they don't make a 10" diameter version.

Vale71, I thought about that possibility, but I concluded that most of their customers would consider that practice deceptive. I think the general expectation is that the yeast that made the beer is in the bottle. Of course you could filter the yeast out, add a bit of dead baking yeast, and call...

Thanks, ebbelwoi! They are heating the beer? Yikes! Couldn't they at least use their own research reactor? (TUM has one in Garching, just down the road.) By the way, I haven't bought your namesake drink, but a mustard made with/from ebbelwoi at Frankfurt airport. Overpriced, but delicious. And...

Hi Konstantinos, a quick update: a) I misstated both my grain bill and the hops; I used 1 ounce Hallertau Mittelfrueh, not Perle, and 7 lbs Weizen and 3 lbs Pils malt, not 5 and 5. b) This paper here...
