list noob saying hello

[Hro]

Hej hej, hello everyone!
I am an uprooted foreigner trying to figure out how to make beer in a country that I have few resources. I have only brewed with friends that have experience, now I am on my own trying to put the missing pieces together "}

I have taken on the challenge to research the limitations of a home system. I am going to first focus on the effects of temperature and water quality on yeast.

I may provide more information in the coming months.

Takk takk!

Welcome! I am a relative newbie myself but I suspect that the only limitation of a home system is one of scale. Not to dissuade you from your research but I don't think you'll find any practical thing that can be done in a brewery that can't be done by the home brewer. What particular sort of limitations are you expecting to find?

hi! I am thinking mostly about the amount of error we can accumulate in a home system. Presently, looking at genetic drift in yeast, one I have been culturing, with water quality and temperature. Yet, I do this all from an empirical and end product (beer) stand point. *I am also fallowing the qualities that can be monitored with electronic sensors ( eg: pH, CO2, O2, CO, C2H5OH, temp, humidity, barometric and optical spectrometry ).

I will at least be able to quantify what I can do with my own system if not predict what one can do from any given home system if that makes any sense.

Anyway, I am just gathering my tools and I will have more to say about this once I have all of my wet lab in place

Bless bless

Pretty detailed analysis for a "noob" intro post. I am interested in your genetic drift yeast analysis. You say you are doing this empirically and I am wondering how useful this could possibly be. I feel like you should be measuring your purity in relation to your "tasting notes." Also, what are you using to measure your other parameters "( eg: pH, CO2, O2, CO, C2H5OH, temp, humidity, barometric and optical spectrometry )" with?

Sounds like fun but as a moderern homebrewer unless you are just a fellow mycobiology enthusiest i dont see what you can hope to gain.
If your trying to push the drift of youre specific yeast in hopes of making a strain unique to youre needs and taste i would be interested in what the end result comes out as in comparison to the hundreds of strain varitals avalible , but even if you are re-inventing the wheel abit sounds like fun!

Hello, I had responded to 'step' and another post last night but the web page informed me, it was waiting moderator confirmation.

VONSEITZ, yes I am reinventing the wheel, but I am new to using my taste buds to help my research

Here is what I had responded

-- Yeah, I am noob to brewing but not science, I work in medical imaging research, and I'm a bit of an electronics geek...
My analysis of genetic drift will be based on the sensors and (yes, certainly) the taste elements I can perceive using A-B-A tests. At the moment I have 16 x 5L vats, each temperature controlled and monitored.

I am using AVRs ( arduino ) and various sensors. I realize these sensors are not 3 sig'fig's --and my test have shown that they are not that accurate, the demo c-code is also suspect--. However, we can see the changes in certain aspects of each batch.

btw for all electronic sensors ( with the exception of the pH & gravity ) I am taking samples every 5 minutes, and monitoring the changes ( stored in MySQL and plotted with php/GD and/or RRDtool )
