Great! As an aside: If I recall correctly, Sean Terrill's calculator to estimate FG from initial and final refractometer readings is based on using the same WCF (something like 1.04) to final refractometer reading, as well as to intial refractometer reading. Terrill put considerable...

danielcook, I'm not sure I have completely understood your question. Is your FG of 1.013 a hydrometer reading or the reading on a refractometer that has a SG scale on it? There are both refractometers and hydrometers that have dual SG and Plato (or Brix) scales on them, and the...

??? Yes, but he's still wasting a gallon of beer. With a different method, he could have brewed less than 6 gallons to net 5 gallons.

I usually use only 1 or 2 oz of pellets, also, when I dry hop. But I was recently following a clone recipe that called for one 3 oz load, and then another 2oz -- i.e., 5 oz total. That was what drove me to seek another method. I would guess that the beer loss with 5 oz of hop pellets would...

Yup. That's reasonable -- if you don't mind the 1 gallon loss. I think I can cut that loss at least in half.

To each his own. However, you'll be doing nothing to reduce beer loss in the hop sludge. Furthermore, some like to hop very late in fermentation (or during lagering) when little off-gas is produced that will strip hop aromas from the product beer.

Yeah, except the beauty of this is that the brew gets pressed out of the hops through the action of extracting the stocking through the carboy neck, and the "juice" just runs back down the inside of the carboy in the process. If you do your fermentation in a bucket, you'll have to do something...

The headspace shouldn't have any oxygen in it, since it's been sealed. And as soon as I put the hop-filled stocking into it, I either purge with CO2 or -- if it's still active -- I swirl and the effervescence off-gas purges the headspace. This particular brew in the picture had a far greater...

Perhaps someone else has already done this... but I thought I'd share a dryhopping technique I've just tried successfully. One problem with dryhopping in a secondary carboy is the rather voluminous amount of sludge that results. Too much of the beer ends up in this sludge, and I hate to see...

I've been brewing and bottling for 34 years. I've never sanitized my caps and I have never, ever, had even one bottle go bad.

You know, if your wort "correction factor" really is 1.07, then your 16.2 measured Brix would correct to 15.1 -- which, with the equation I use, converts to an estimated SG = 1.062. So maybe you're OK after all. I'm just not used to seeing a 1.07 'correction factor.' That still leaves me...

The equation I use for estimating original SG from refractometric Brix is this one: SG = 1.000898 + 0.003859118*B + 0.00001370735*B*B + 0.00000003742517*B*B*B http://www.primetab.com/formulas.html which gives 1.067 for 16.2 Brix. 1.062 would correspond to about 15 Brix. I have found...

For clarity: I'm referring in previous message only to the analytical technique involving measurement of Brix on a sample and on a boiled, reconstituted sample. And whenever I use the term "Brix," I'm referring to a refractometer reading, not the use of a Brix scale on a hydrometer. I'll...

If you're referring only to final SG estimates, well those don't really come from my model, per se. I employed an often-employed polynomial that uses initial and final Brix (from refractometry) to estimate final SG. I did this because, as explained in the Documentation, I don't really care...
