Homemade yeast

  1. Mar 8, 2017 #1
    am interested in making my own brewery yeast from scratch from fermenting fruit. Is this possible? If yes,will it yield good results ? What is the process ? If no,what is the best way to make my home yeast.

    By "brewery" do you intend brewing beer? It will be a hit-and-miss experiment. If fermenting fruit, I think you have the advantage that it brings in its own suitable yeast: grapes, apples for cider, and plums for vinegar, for example.

    I believe I have seen ginger beer home-brewed where the yeast involved was provided by a few sultanas dropped into the bottle. With the sugar solution and warmth, it multiplies and produces gas and flavours.

    Sour dough is bread made using yeasts you can harvest & you grow yourself. The bread smells a lot better than does the bottle of frothing yeast!

    Good luck with your experiments!

    Thank you very much for your response. Actually production of ethanol is what i really want to use the yeast for.i want to know how to make my own homemade yeast that will be suitable for high ethanol production using fruits waste. Can you put me through on DO IT YOURSELF from the scratch?

    I appreciate your link. Actually i want to use the yeast for the fermentation of fruit waste for the production of ethanol. But the link give enough information on how to make baking yeast which is not the best for high yield of ethanol due to it low sugar tolerance. I will be very grateful if you can help me with any information or links that will teach me DO IT YOURSELF. thank you.

    That sounds to be getting very specialised. I don't hear of DIY alcohol fuel projects, so it is probably uneconomic. You are basically wanting to produce strong moonshine, for fuel?

    I think there may be a danger of unwittingly producing toxic methanol along with the ethanol—weren't some moonshines poisonous? Besides garden compost, the only use I know of for waste damaged fruit is in making homemade vinegar.

    Yes it is possible, but you can buy cultured yeasts very easily and not expensive.
    As far as I know yeast and byproducts of yeast have been an industry for several thousand years

    You really got me correctly, I want to use it for fuel but not for consumption. The reason why i choose to go for fruit waste was there abundant availability in my area which is causing serious environmental hazard. Therefore, am looking for a way to convert this waste to something useful. Therefore, as a matter of necessity, I will need and helpful information to make this a reality. Thank you.
    However, I will not hesitate to learn how to make cheaper ethanol for cooking fuel. I am open to learning. I will be eager to hear from you Sir.

    It sounds like you'd need to go to commercial scale. It needs distillation to extract the alcohol, and what cheap energy source will you use to heat the still? http://www.heliotrack.com/Solar-Ethanol.html

    OK. I that is what am really going into,I mean large scale production. I know fully well that I will need distillation chamber and other things that may be attached to make it happen. But as a startup,you need to do some experiment to and start on a small scale before you scale up your production. That is why I want to grader enough information before I fully go into it Sir. Thank you so much for your interest you show on my project. I will glad if you will not hesitate to be my mentor and guide on this.

    You will have to do lots of googling to find out more details from the experts. I have told you all I know on this. :smile:

    Best of luck with your brewing enterprise.

    Further thoughts on uses for waste fruit: producing biogas (methane) for fuel might be a more realistic proposition, providing the chemistry allows it.

    Also, composting for garden fertiliser (need sufficient heat to germinate and/or destroy the fruit seeds), or maybe a worm farm then harvest the worms to be food for some sort of stock (chickens, pigs, crayfish, etc). :smile:
