Stereotypes: Brewers have beards

14 January 2017 - 11:44 PM

In the thread about 2017 lamb ad, the topic of stereotypes came up. That lead me to ask the question of:

 

Are most beer brewers bearded?

 

Let's see...

Another rye porter - feedback wanted

11 December 2016 - 03:42 AM

I'm formulating my very first all grain porter recipe from scratch and planning on using a Grainfather to do this. I would appreciate feedback on this recipe and in particular the mash. I can do a more complicated step mash if that would give better results.

 

I'm limited in the variety of the grains I have on hand, but I have enough in stock to alter the quantities.

 

I also have a reasonable selection of hops, including Citra, Chinook, Centennial,  Columbus, Cascade, East Kent Goldings, Mosaic and Simcoe. So, I could change the hopping if my choices seems inappropriate. I'm unsure if I want to dry hop this or not. I was thinking I'll evaluate fermenter samples and if it seems like it needs more aroma, throw in a handful of Citra (possibly into the keg)

Water SG less than 1.000

03 December 2016 - 02:44 AM

This one has me scratching my head. I have a hydrometer calibrated for 20C, one refractometer calibrated for 20C and another refractometer with ATC. A few months ago I checked the hydrometer with filtered tap water at 20C and it was reading bang on at 1.000

 

Today I was playing around with the refractometers and put a drop of the filtered tap water on the ATC model. It was reading less than 0%. I checked the temperature of the water and cooled it slightly to 20C, then used the water sample with the hydrometer and it was reading 0.998. The ambient temperature was 22C and the refractometer calibrated to 20C was also reading less than 0% Brix.

 

Why would that be? Why would all three instruments tell me that the SG of my filtered tap water is not 1.000? In fact, all three actually agree in the magnitude, since the refractometers were reading about -0.5% Brix

"0 warning points" is displayed next to my posts in the user info. Most other people don't have that. What does it mean and how did it get there?


Calibrating low pressure gauge

20 October 2016 - 09:21 AM

Is there a simple DIY method for ball-park sanity check/calibration of low pressure gas gauges?

 

Something along the thermometer 0/100C, icebath/boiling water trick.

 

I only have one regulator with high and low pressure gauges. I am starting to suspect the value shown by the low pressure side. Most people talk about using 10-20psi in their setups. I find that I get my optimal results in the 20-30 range. I have no issues with how my beers pour, but it would be nice to know whether the actual CO2 pressure is anywhere near what the gauge is actually reporting.
