I have found that small openings lead to very long brew times. Here's an

example: I have both 1-gal jars that are taller than wide and have

narrowed opening at the top, as well as 2.25 gal vessels that are wider in

relation to the height, with straight sides so that the opening is almost

the same diameter as the vessel itself. If I set a brew up in one of each

of these two vessels, the 2.25 gal container will get done first.

Now, we all agree that the 1-gal jars are fine to brew with, but

nevertheless brews in those jars spend a lot more time sitting and looking

pretty inactive, compared to the big vessels. It has to do with two

things, but I firmly believe it is both these things: 1) vessels that are

wide and less tall brew faster, and 2) vessels with wider openings brew faster.

I'm not a fiend for quickness on the KT, but I certainly wouldn't choose to

brew my regular brews in vessels with small openings. To brew in such a

vessel in order to have vinegar in a bottle, fine, you're not needing it

to provide your supply of KT.

That's what I know about it. THere may be other reasons as well.

Oh, here's some more info on this. Vessels that don't have enough airspace

in them, most particularly ones with narrowed necks such as the gal-jars,

also have been known to sit and sit and SIT! without getting ready. I'm

talking twice or more as long. We had a slew of people one time on this

list all of whom had brews just sit sit sitting, and every one of them

solved the problem by pouring out some of the brew and increasing the

airspace. In their cases, they didn't know any airspace was needed, so

there was no airspace at all.

It's an oddity of this list that the same query will run in spurts where

several people will ask the same question all at once. Like earlier today

about the cloves and orange spice tea.

The light really does not seem to be an issue. Plus, you can use a large

cloth as your cover cloth that also covers the vessel. Mine are

lightweight white floursacking type cloths that are tightly woven. In the

summer my vessels get a few minutes of direct rays and the brews seem to

love just those few minutes. For sure, I have noticed no trouble at all

with the light in our kitchen, and we have big greenhouse windows. I use

large 2.25 gallon glass containers (they are made by Anchor Hocking as

cookie jars). I'm sorry that these don't seem to be available in other

countries than the USA.

I remain a beginner at KT fermentation. My first batch is working in

a gallon brown bottle.

Both wooden barrels, and Italian wooden spigots can be

purchased from Northernbrewer.com....2-5-10 and 15 gallon barrels

are available from 120 to 200 US dollars. If you want French oak,

expect to pay much more as it is air dried and not kiln dried. I was

thinking, if the barrel is on it's side with the bung hole facing

upward and filled to 75% capacity, we could take advantage of the

increased surface area for speedy fermentation. The Belgian brewerys

which ferment with Lactobacillus pump the hot wort (unfermented

sweet liquid) into large shallow tubs in the attic; i.e. head-space

Hi all,

It seems to me that the most important factor is not the opening in

the container, but the surface area of the liquid inside the

container. That's where the alcohol produced by the yeasts is oxidized

to acetic acid by the bacteria. As the oxygen is consumed at the

surface, it will be exhausted in the head space and will diffuse from

the outside air. Unless there is a significant restriction of bulk

flow between the outside air and the headspace, there will be plenty

of oxygen for the bacteria. The difference between, say, a pickle jar

and a liquor bottle isn't going to effect the gas exchange very much.

A more significant factor is the enrichment of the headspace with

carbon dioxide, which is heavier than air. Even so there should be

enough oxygen to do the job...

So as long as you're not filling the liquor bottle up into the neck,

it shouldn't be that different from a pickle jar of the same size. Now

if you *did* want to get the scobies back out that's a different story.

The 2.25 gal one is pretty big. You might look into packing whatever you

buy and sending it the cheapest method home.

I'm afraid this would not be sufficient air access. I've discovered that

even if the barrel were only partly filled, if the air hole was just the

small bunghole, it would probably not be enough.

My idea was to have one end of the barrel sawed off as the open top, then

sit the barrel on the other end. So the top would be open and still

covered with the cloth. It would be more akin to a pickle barrel in this

usage, except I would really love to have a spigot down 2-3 inches from the

bottom.

Thanks again. Your perspective is helpful.

Well, I can tell you from experience, and I am very observant, that it may

not seem like it should make a difference but in fact it does. I promise

I'm not theorizing, I'm speaking from long comparison brewing. :) --V

Ok, I get you. I think that what I was trying to point out was that

it would not harm the scoby. (at least it certainly has not hurt

mine) Of course I use my big jugs (with big mouths) and my contious

brew urn for brewing but I could not think of anything to use for

some good kt vinegar until I remembered a couple of old bottles we

had from past Christmas cheers. ;)

I don't really mind that it is just sitting because it was very

vinegary when I put it in there and is great in salad dressing.

Yes, definitely a situation where the time factor doesn't matter.
