What differences have you noted between "force carb slow and steady" versus vigorous shaking? I've gone the full route from leaving it alone for a day, rocking gently, and even violent, harsh agitation, and not noticed any difference. (Carbonation pressures are those recommended by BeerSmith for...

Thanks. That's good advice. This is looking un-fun at the moment. Reconditioned 5 gal cornies cost less than the new posts + adapters + pipe fittings. Foxx lists a good selection of adapters for Cornelius and Firestone posts. 1/4" MPT is closest to most universal, if someone else wants to...

I want to make a mini keg tapper that takes standard ball lock disconnects. What fittings will I need to mate with gas and liquid side port valves? Thanks. Mike.

I would dump the solution you used to cleaned the copper immediately. The little black floaties are copper acetate if cleaned in vinegar; copper phosphate if you used StarSan. The temptation with StarSan is to continue to use the solution to sanitize everything else. Yer killing me. I don't...

You can do as you like, of course, but do so knowing the facts. Copper oxide reacts to form copper salts in acidic environments. The typical use of copper lines in homes is as water supply lines. Supply lines are almost always continually submersed under pressure in potable water. Conversely...

An estery, somewhat alcoholic flavor or aroma might indicate the yeast was overstressed. Hard to say from your description if that is or isn't the "sharp" flavor. How did it look in the primary? It might also be just the hop bitterness, which might come across as astringent without the aroma or...

To expand further, the fixation on acetic acid comes from formation of copper acetate, one form of verdigris, if the acetic acid is allowed to remain on the copper when it dries. Oxidation then forms copper acetate, rather than the more benign copper oxide or carbonate. Copper acetate is very...

Look over the water tab. It tabulates the losses at every step. You can set those in the equipment tab to match your setup. If you tell it you want 5.001 gallons at bottling, it'll adjust your water so you end up with 5.001 gallons after all losses.

The latent heat of fusion of water is about 150 BTU/lb. It takes that much heat to convert one pound of ice to water. One BTU is the heat required to heat/cool 1 lb of water 1 degree F. Thus, melting 1 lb of ice chills 10 gal of wort a little less than 1.7 degrees F, leaving about 4.8 qts of...

I offer this to clarify, not to negate or dispute. Head is measured from the liquid level, not the kettle outlet. It would be under positive pressure with the kettle liquid level above the pump inlet. Also, total head is measured from liquid level to liquid level, assuming the discharge is...

If it helps understanding, centrifugal pumps are described as constant head machines. Within some limits, the pump could be at the top, middle, or bottom of that 18'. Placed at the top, all the head is suction. One of the limits was described in the linked document as negative suction pressure...

Thanks, Juan. For sure, seeing is believing. The 4' head on the non-HS series pumps is barely enough to push the bottom of one keggle to the top of the next.

Bump. I would dearly love to know how much suction head a March 809 and other pumps can pull, more for general knowledge than to settle the false bottom question. Here's a link to an article about pumps and net suction pressure head. Of particular interest is Figures 2 and 3...

I'm still lmao reading some of the older threads. Had no idea it was such a cutthroat market. :D I wonder if you can understand what I'm going through. These things are, like, OMG it's 1980 again and I'm reading the IC Cookbook with LM317 and 555 timer hacks. And I somehow can't get myself to...

I'm guessing some trace amount of alcohol remains behind no matter how long the boil, possibly related to partial pressures or such. Somebody somewhere can probably calculate that amount precisely. I doubt we can measure it with a hydrometer. And therein is the question: Is it real if you can't...

What kind of pump are we talking here? The 10 psi of suction head mentioned earlier is clearly an exaggeration and in the realm of vacuum pumps. It's simply out of the question for centrifugal pumps. We can also rule out cavitation. Lautering water at 170^F boils at 8.7 psi of vacuum. That's...

Wouldn't the hose just collapse? The same external air pressure that collapses the FB is at work on the much more flexible hose.

I think that's allowed only if you bottle the condensate and ship to me for disposal.

In a word: Workflow. BeerSmith is OK for many things, but doesn't adequately fit a workflow. It has a pile of tools or screens that cover many of things I want to do, but it doesn't really work with me on what I'm doing. What am I doing? * I'm editing recipes; * or planning a brew; *...

Thanks. That all sounds right. The linear drive magnet from a HD is practically free, incredibly strong, and draws no power. The trouble is, I still need a stir plate, but all the dead power supplies here died of cooling fan failure; no muffin fans on hand. I have a few CD drive motors that I...
