natural yeast killing

Not really. they may go dormant and may have difficulty starting again if warmed up. But a year down the road you may be awoken by the sounds of coke bottle grenades in the basement.

I'm an EC-1118 guy and a 2L soda (PET) bottle guy. Due to the opportunity for oxidation, I use 2L only when the contents will be consumed in six weeks ao less. But a three month storage is probably ok.

As for lowering the temperature to kill off the yeast, my experience is that lowering the temperature MAY cause the yeast and other materials to drop out of the suspension and settle to the bottom. When I get my new (at least to me) freezer moved downstairs, I will put carboys into it before post-secondary racking. (I'll start at 8 hours and look every hour until I see signs of freezing.)

I store in glass carboys and bottle timely before use. There has NEVER been a bottle grenade in my house which is one of the reasons I am still alive and allowed to brew here.

I'm currently doing an experiment of secondary fermentation of twice-racked 'off-dry' zinfandel in a sealed plastic 1/2 gallon cranberry juice container. Yes, the container expands due to the released fermentation CO2. At month 4, I have to release the pressure every two weeks by cracking the lid a skosh.

Not sure I'd want to make a habit of drinking said PET plastic-bottle-fermented wine because of extracting low molecular weight PET monomers into the wine. But as an experiment, I don't mind a taste.

I just finished racking my first prodcution batch of peach wine.

I wrote my conclusions down in this pdf file:

Really I wanted to experiment on a zero budget. I have succeeded in making alcoholic wine material for $1/L Canadian, making it 'more than an inexpensive drink, but the most inexpensive drink of any kind'

It seems 15%. Not a lot of character.

The good things maybe about the 2L setup, is that maybe you can isolate the occasional bad batch in one bottle, it is easy to pour rack, and they wouldn't hurt you if they ever did explode.

but no we're in business with $5. with 2L coke bottles.

It is OK, like I say the cheapest drink.

FYI I still think methanol and likes put you off but the full fermentation process moreso evaporates them, so yo have less if you wait for the full high alcohol ferment and avoid energizers....

It is nice to let a bit of gas outlet at least to allow the methanol escape.
