Never trust the specific gravity scale on a refractometer. It is not possible to convert the refractive index of a solution to a specific gravity, without knowing the makeup of that solution,...

If the slurry is a month old, I would definitely make a starter. I might be tempted to omit the starter, if the slurry is just a few days old, but in my case, this never happens.

As far as I'm concerned, the published attenuation figures appear to be a work of fiction.
For example, WLP002 has a published attenuation of 63 - 70%, but I regularly get 80% from the first...

Are you using the reading directly from the refractometer to get your FG value, or are you processing the refractometer reading through some sort of calculator to get the FG reading?

Ye, I am very familiar with the style. It's been my go-to beer for over 50 years.



Actually, NB uses ~7 oz corn sugar per cup.

I'm also not sure that most Americans don't care for low...

The priming sugar calculator assumes 1.5 volumes CO2. While this may be reasonable for a draught beer, it is totally inadequate for a bottled beer. For bottling, I would aim for a minimum of 2.2...

You've got it. I no longer check my temp at the end of the mash, because (when I did) I found that I'd never lost more than 1 or 2 degrees. If you don't stir, the mash out water will be sitting on...

You can always take a Brix reading, and not bother to convert it to SG. When the Brix reading stays stable for 2 - 3 days, fermentation is finished. You can then use a calculator to get an...

I also brew 5g batches in a 10g MLT, do a mash out, and fly sparge, and get a consistent 75% brewhouse efficiency.
I don't have a thermopen, and use a 5g cooler as a HLT; but I doubt that makes any...

I'd spend the whole $200 on your wife. That way, she won't be quite so upset if she ever finds out you refer to her as an "old lady."

If you take 1 lb LME, and mix with sufficient water to make 1 gallon, you will end up with a solution with a SG of 1.036 (according to Beersmith).
This means that the weight of the solution will be...

Technically, this isn't extract plus specialty grains. Wheat malt and Pilsner malt are both base grains which require mashing. As you steeped them at 155 for 45 minutes, you performed a mash.

On the other hand, if you want to play around with mash thickness, 1 lb grain occupies a volume of 0.32 qts when mashing, so multiply the weight in lbs of grain by 0.32, add the amount of strike...

I usually use 1 US qt water per lb grain for the mash, and fly sparge with up to 5 gallons sparge water. In a 5 gallon cooler, I could get 13.5 lbs grain, and still have a bit of space left over. ...

In my opinion, 155 ppm Cl is much too high. I would reduce it to a maximum of 30, and (when you drink it) make a note of the difference it makes.

Did you cool the sample before taking the hydrometer reading? Hydrometer readings taken at over about 100F are very inaccurate even if you do apply temperature compensation.
