Hi,
I recently bought a microscope Kern OBS 116 for yeast cell counting:

The problem is that hemocytometer grid is visible only on lowest (40x) magnification:
After changing objective to 100x magnification...
OK, for the first time I have keg foaming problem.
System is well balanced, it is not new one, actually I made it few years ago and it served me well in the past.
I have couple of kegs that's been maturating for ~14 months so I decided its time to clear them out.
So I set them in keezer and...
I am in the middle of buying another thermometer and ran into interesting offer on ebay, refurbished Thermapen for £28.80 (~ $46).
According to seller units are supplied in like-new condition and include the full warranty. All include a calibration certificate...
Process is simple: pour piece of filter paper in yeast suspension and wrap it in foil, it can be submerged in wort as 1st step or sample to plating/slanting, everything should be sterilized.
I am thinking to take a sample with paper towel or something less impure, leave it few days (shipping)...
At the moment I decided to build HERMS I got two kegs and plastic bucket. I decided to use bucket for HLT only temporary, but with time it turned out as cheap and functional solution, it is made from HDPE(High-density polyethylene) which can withstand higher temperatures (120 C/ 248 F for short...

All my kegs are pin lock, so there is no pressure release valve.
Since sometimes I leave keg on longer aging (without carbonating) I want to ensure that there is minimum oxygen left in it.
Before racking I purge the keg with CO2 for few seconds (lid off) and then rack the beer under CO2...
I"ve read that bacteria can became tolerant if we are using same sanitizer continuously.
What I am wondering is:
- is this entirely true or there are some special circumstances (type of sanitizer, concentration..)?
- how long to use one sort of sanitizer and when to switch to another?
- is...
I am brewing sweet stout this weekend and I have two options:
- use 100% RO water and manage water profile completely
- use RO and tap water in certain percentage
My tap water profile:
Ca- 170 ppm
Mg- 65 ppm
Na- 4 ppm
Cl- 13 ppm
SO4- 17 ppm
HCO2- 305 ppm
Grain bill (10 gal...
After some thought, I decided to give it a shot and try to make keezer and fermentation chamber in one.
Actually it will be a two freezers connected via flexible or PP tube, where blowing and exhaust will be performed with PC fans controlled by STC100.
Freezer for fermentation is set vertically...
I bought used Celli taps and new o-rings in order to change the old ones.
Problem is that I got 8 o-rings, and after dissembling tap I noticed that there is only 4 that I can change (as you can see on picture).
Anyone knows where the other four are placed, and is there a way to unscrew spout...
Last night I listen BYO/BBR experiment about mashing time (10-30-60 minutes @ 159F). One of conclusions was that shorter mashes resulted with higher attenuation wort (more fermentable sugars). Kai mentioned that beta amylase first becomes inactive while alpha proceeds to convert starch and long...
Finally I bough RO system and I decided to learn more about water chemistry in order to create water profile for my next batch. I read Brun Water Knowledge (which is excelent) and few articles just to get some basics... I am trying to workout my new water profile with RO water using EZ Water and...
I made conversion chart that shows FG values for different OG"s, with percentage of yeast attenuation.
That was something that annoyed me when I started to work with refractometer, but not anymore..
It cover values from 15 Brix (1.061 OG) to 11.8 Brix (1.048 OG) with related attenuation...
I"ve been working on this for last two months and finally got some visible results.
Main idea is to build basement brewroom with workshop where I can build/repair and brew some beer.
Setup will be hybrid electric/gas HERMS (electric elements for HLT and gas burner for BK).
This is how...
Hello to all of you!
I have dilemma on how to connect and wire two heating elements and one PID, I hope someone will help me out with this.
This is my setup:
Auberins SYL-2352
2 SSRs 25A
2 Heat sinks
2 2000w 220V heating elements (both in HLT)
I will use two heating elements (2 x...
I am at the beginning of setting my new RIMS and after a lot of searching and reading I choose to go RTD/PID route right away on temperature monitor/control.
Temperature will be measured in 4 places:
- HLT- RTD sensor
- RIMS- RTD sensor
- MLT- RTD sensor
- CFC- K Type sensor
Since I...
I am looking for PID that will suit for RIMS, after I"ve searched forum I am richer for few info's:
- PID has to have SSR output
- PIDs with 2 displays show current and set temperature, ones with one display show only set temperature
- we can use K-type or some other temperature probes
Please...
