So we might also stock some PET bottles as well. If you guys could choose any PET bottle size to use with this cap what size would you choose? We could make any size from 1L up to 5L. The bottle cost would not be very high. Only a few dollars per bottle. The increase in size would not have a significant increase in price. So to get your feedback what size would you guys prefer?

I would say definately a 5L option, and possibly a 1 or 1.5L for taking a couple to a BBQ or similar

A PET bottle that fits in the 4L mini keg parka would be good. (The 5L is too fat to fit in a Kegerator together with 4 X 19L or in many fridge doors.)
 
Do you have a rough idea what the dimensions of the bottles would be?

My place isn’t big enough for a kegorator, and having these to go in the fridge door would be awesome... (much much cheaper than mini kegs!)
 
2 x 5l, one with water and one with beer line cleaner would be perfect for the keezer
 
Given they've put "65 psi" on the side of the adapter, I'm guessing they reckon a PET bottle is good to about 65 psi!

(I've force carbonated at 40 psi many times, and used up to 120 psi for bottle rockets, so 65 feels reasonable to me)

Yes that is correct. The PET bottles would be safe to be used at 65PSI if we ended up making them. If we went with a 5L size the height would have to be about 50cm tall. This height would make it difficult to fit into an esky or something. Would that bother you or given the large height would you prefer to have a 3-4L size that is about 35cm tall?
 
Haha true, so plenty.


Also had a question for Kegland regarding their kegerators. I'm thinking of purchasing one soonish, is there anything on the horizon for updated models or other fridges worth mentioning before I do? And also I can't find any warranty information about your kegerators, whats the warranty peroid on them? Thanks

Kegerators are 1 year. Basically all the new products we sell are 1 year warranty unless otherwise stated on the website. For instance we do have longer warranty on other items such as Kegs (10 years warranty but this is stated in the description)and BrewZilla (3 Year warranty as you can see here). So the best thing to do is look at the product description for warranty and if it doesn't state the warranty in the description then assume it will be 1 year.

What about 2.5 litres, they seem pretty cheap too.

I would go a 1 Ltr, a 3.5 Ltr and a 5, just to cover all bases.

Yes we did try those ones specifically but we had two issues with them.

The plastic in these is just mono-barrier straight PET with tint. No other additives were used so the gas transmission rate is a bit high and not really good for long term storage. These bottles are used in China as disposable growlers primarily.

The other problem is they were really weak. The 3.5L size burst in the drop test from less than 1 meter high. So I think you guys would be disappointed if we stocked these. To be honest it's a real issue with the current PET bottles sold for home brewing in too. Many of them are really not great for long term storage (over 6 months) as the oxygen that passes through the PET is too high for this application. It's just not really spoken about amongst home brewers for some reason. If we find time one day we should do the lab testing and release the results publicly but not all PET bottles are great for long term storage of beer.

If we spend about AUD$0.50 more on the preform we can get a barrier layer in the PET so it will be suitable for much longer term storage of beer without the oxidation issue. It's a much more complicated preform to make and it would have to be custom made for us but I think its worth the extra cost especially for a re-usable bottle.
 
I’m still away from home but if you measure the 64 oz stainless growlers with the drafto top which I think are about 330 tall all up
The growlers that I use are from eBay and keg king ( single skin non insulated) which I think are about 175 mm at the base.
These growlers are tapered at the bottom to allow them to fit in the fridge door shelf
The door shelf has a lip on the bottom ( in our fridge)

Thanks for that. Much appreciated.

I would say 4 or 5L. You can get bottles up to 3L with soda in them for a couple of dollars.
 
I'd go a few 4litre ones just for soda water in the fridge. The 5litre would be to tall. Make a soda bulb adapter to push it out a tap and i'm sold.
 
Hi guys, I recently purchased a MFL Shank adapter from KL (https://www.kegland.com.au/stainless-mfl-tap-shank-adaptor.html), the issue is I can't get the adapter to seal against my Intertap FC . There's a mention of a nylon washer being recommended but in this case the adapter seems pretty useless with out it? As when tightened the adapter is loose on the back of the tap. Anyone used one of these?
 
Hey @KegLand-com-au, could you please add the G40.1 manual to the product listing? At the moment it links to an STC1000 manual, there's nothing about the chiller unit itself.

Thanks

Please have a look at this diagram here. Do you have the seal 11 in your tap:
http://www.intertap.beer/Downloads/Intertap 8473-G2.pdf

You need to make sure this seal is in good condition.

We do talk about a nylon olive as well but this goes between the disconnect and the adaptor not between the adaptor and the tap.

Thanks for the heads up. We will get that uploaded for you. In the meantime do you have a specific question and we can give you the answers now if you like.
 
I would say 4 or 5L. You can get bottles up to 3L with soda in them for a couple of dollars.

It depends on what you are using it for. The soda bottles are cheap and available but they do not have sufficient barrier properties to block the gas transmission through the plastic. So for very short term storage they would be ok but not for storing beer for more than 1-2 months.

Thanks for the reply, I wouldn't think I'd be using any of the bottles for long term storage (more than 3-4 months).

However, now you've mentioned this I'm interested to understand what the properties are of the soda bottles you've assessed? Assuming that new, sealed lids are used on recycled soda bottles, specifically how much gas is going to penetrate the PET?

I don't do it often, but I have stored sour beers in cheapo soda water bottles for ~3 months before with no noticeable issues; I also won a small home brew comp a few years ago with a hoppy American brown ale that was bottle conditioned in reused soda water bottles (2-3 months from packaging to consumption).
 
Yes I dont thing this would be a good idea. The spunding valves are fairly easy to clean and with a phillips head screw driver takes about 2 minutes to tear down as you can see in this video here:


With that said we have been giving our Blowtie here some punishment and it's frequently had krausen go through it and to our amazement it seems to be operating fine even without a clean. So you never know, you might just get as lucky as us and just keep using it without cleaning it.

If you really want to protect the unit then I think the best thing to do would be to make a small receiver/settling tank so the gas runs into this before going into the blowtie. To make a small tank you could use a PET bottle. In fact it was mentioned in this thread a number of pages ago that we would make a tee piece that will enable you to use two of these caps, then use these yellow KL14830 fitting to connect two of these pieces to a coke bottle:

So this would be a fairly inexpensive way to make a receiver/settling tank. It will also be able to be used as a very inexpensive small keg too.

@KegLand-com-au do yo have an approximate ETA?

Yeah I do have the seal 11 on my tap and its in good condition, I use a non KL chrome plated adapter and it seals fine. The issue seems to be when the adapter is tightened up as far is it can go it's putting no tension on the adapter onto the back of the tap. I've got no tension at all in other words. It's not that its a bad seal its that there is no pressure/tension for it to form a seal. Hope that makes sense.

In a cheapo soda bottle you will notice that after about 12 months approximately 20% of the carbonation will be lost and a significant amount of oxygen can come into the beverage in that time but soda is not a particularly oxygen sensitive beverage so this is not really a problem. The exact amount of oxygen ingress and CO2 loss can vary quite a bit depending on the pressure, temperature and humidity. If the bottle is cold and dry the gas transmission rate can be halved. Also the size of the soda bottle is an important part of this equation as well. A large 2Liter soda bottle has less surface area to volume ratio so the oxygen ingress will be less when compared with 500ml bottle. So bigger is better in that regard.

Other factors to consider are thickness of the plastic. As the PET gets thicker you have pretty much a linear relationship between thickness and gas transmission rates. So thicker is better.

So it's difficult to give you an exact OTR (oxygen transmission rate) on your particular bottles without knowing exact thickness, stretch ratio of the bottle, grade of PET, temperature and humidity conditions for the storage, but I can say that normal PET is certainly not a good option especially in small bottles, stored at room temp and definitely you will have significant degradation which is why normal PET bottles are not used for beer commercially.

If you include a barrier such as EVOH layer in the PET preform this is quite a bit more complicated to make but this is one of the best ways to reduce the gas transmission rates. You can reduce the gas transmission by 100 times or greater depending on the barrier used. So this can easily turn a PET bottle that would only be suitable for beer storage of 2 months to well over 24months. I am not sure if you remember the "Tap King":
tap-king-varieties.jpg

I am pretty sure Visy manufactured these using a EVOH multi-layer preform or nylon additive for this reason. I can assure you they would have used a much cheaper and less complicated preform if they could get away with it.

So getting back to it your sour beer and your American brown ale would certainly have been exposed to some oxygen. If you have a dark beer this is less noticeable. For a stout you can get quite a lot of oxygen in the stout before it's really obvious. The exact amount is hard to say but in a cheap soda bottle it would be significant. For lighter styles of beers like Lager or Pils then this will be much more noticeable and I would not store these in cheap PET at all unless you are really drinking them fast.
 
@KegLand-com-au The thermowell for the fermzilla was due in today. Didnt get an email and been checking all morning but still out of stock. Now saying not due till 13 oct. Did some come in and the date updated to next delivery but stock level not adjusted?

Yes sorry about that. We decided to delay this one. If you look at the photo on the website:
https://www.kegland.com.au/60cm-thermowell-1-4inch-duotight-bulkhead-included.html

We used to have a plastic 1/4 inch nut that was included in this assembly but we had one break so we are upgrading all the nuts on the duotight fitting to stainless now. Sorry about the wait.
