    foam can never be resolved... bad design
    It doesn't matter how low you run the pressure. you will have foam, wasted beer and flat beer. the valve at the tip pushes the beer through a 90 degree angle and a reduction. It seems that they intentionally designed a foam inducing mixing tip. I would try the counter pressure accessory fix, but not for an additional $50.

    Consistent low fills
    Just filled a dozen bottles and they are all low fills, even though I dispensed till liquid came out the top and capped immediately. Would appreciate some tips.

    Excellent with a few steps.
    Used it three times. The first two were disastrous, on account of user error. Third time was spot on perfect. Few tips:

    1. You must freeze the bottles. Get them as cold as you can.

    2. For that matter get the entire assembly as cold as you can.

    3. Highly carbonated beers will probably be a problem. The first two were over carbonated which I believe caused most of the problems.

    4. Do not bleed the pressure off the keg when you start.

    Most important out of all of these, make sure everything is as cold as you can get it.

    foam foam foam foam
    It would seem that this device was simple to use, but it causes endless foam no matter what I do. I have 39 degree kegs and 10' lines and nothing changes. I can only fill my bottles about half way before the foam fills up the remaining space and overflows. You cannot stop and wait for the foam to go down either because as soon as you start to fill again you can hear hear the wand actually blowing bubbles and causing all sorts of additional foam. I have dropped the co2 pressure to 3 lbs and it still foams. I even ordered the $49 counter pressure adapter for it, but that is cheap, doesn't seal well at all around the wand, and was a total waste of money. The whole thing is a disaster.

    Nice finish
    Filled a 12 pack of dead ringer IPA left over in my keg to free up some space today. After initial setup and sanitation, the filling was very strat forward. I purchased the foamless finish even though it was A little overpriced but it did help with the foam. I would suggest chilling the bottles to the same temp as the beer keg to also help with foam. The foamless finish adapter was a little finicky to get a good seal around the steel pipes but it still did the job of keep top pressure on the beer when purging only what was need to fill slowly. Don’t be in a hurry to fill the bottles though. It takes close to 45 seconds to fill a bottle at 8psi and the foamless finish seal. Overall I’m satisfied with the product and feel this as close as I can get to the big boys carbonating bottles to distribute.

    Bottle Filler
    I used a counter pressure filler for years and frankly I hated the thing. Sure, it left me sediment free beer in the bottles but I usually wasted a lot of beer getting those full bottles and seems like lately many of them ended up flat after I fought to get the beer in them. This thing works great, easy to use, relatively little waste, easy to set up and easy to clean. A winner.

    How do I use the Last Straw with this system?

    Draft Brewer® Twin Keg System
    Draft Brewer® Twin Keg System
    During bottling, noticed a lot of foam being generated in the tubing by the last straw connection between bottles. This caused a lot of foam to be created as filling. After capping the bottles and letting rest for a day, the beer has a slight carbonate to it but no head of foam as when serving directly from keg. Any possible reason? Beer was kegged at 40 degF at 12 psi for one week. Used the last straw at 10 psi. Not sure if co2 was escaping or equalizing due to loose fitting in the straw.
    A shopper on Mar 27, 2017
    BEST ANSWER: I'm not an expert, but I have had good luck with 'the last straw'. The only difference between what you described and what I do, is that I get the bottles COLD - means equal to the temperature of the keg (you said 40F) or less. That way the CO2 does not try to escape immediately upon hitting a warm bottle.
    My kegged beer usually sits at 10-12psi for a week. Even after purging bottles for 3-4 secs and backing the psi down to as low as 3psi, I still get excessive foaming. Which is frustrating.
    Seals and ball lock appear to be snug. But, I still see bubbles throughout the tubing as I fill my bottles.
    Someone suggested cooling the bottles first which I will need to try next time. But, are there other factors I should look into as well?
    F L on Jan 29, 2016
    BEST ANSWER: Thanks for sending us this question! Are you using the tubing that came in the kit and you haven;t shortened it or anything have you? The tubing needs to be the right length to balance the pressure and resistance and get the right pour. I wonder if anything is loose? Check that the bottom is tight and has not come loose, same with any connection. Did you install the nylon washers at the barbed swivel nuts? How does the action of the top and bottom assemblies seem, easy to press? I hope this leads in the right direction! Please reply to let us know! Photos can say a thousand words so could be helpful!
    What pressure should the beer be carbonated at in order to fill and cap 12 oz. bottle so they can sit a while without the beer going flat? I also noticed in the video that while filling the pressure for the keg and last straw should should be at 8 lb. psi.
    Matthew Frailey on Nov 17, 2015
    BEST ANSWER: Hi Matt

    The key here would be to ensure that you get a good seal on the bottles. That is the most common reason for beer to lose carbonation with age. One trick you might want to think about is dipping the bottles in wax. This also helps to prevent oxidation as well.

    But I would carbonate the beer at whatever volume fits the style

    as usual.

    Hope that helps

    let me know if I can help further.


    What's the box size? Trying to know if this will fit in my luggage.

    BEST ANSWER: In inches, the dimensions are 24 X 4.5 X 2
    Can you add a Snake option as well? I know I can adapt it myself but would rather not pay for fittings I won't use.
    M A on Jan 17, 2016
    BEST ANSWER: We will consider it, but most all of our customers would be filling from their soda kegs, and not from Sanke commercial beer kegs. This can even be a bit harder, as commercial kegs tend to be carbonated to a high level, for use in long-line beverage systems; where you can more easily control the carbonation levels of home-brewed beer. But I will pass along the suggestion!
    Hello, I was buying this for a gift. How do I know whether to buy a ball lock or pin lock?
    A shopper on Mar 20, 2017
    BEST ANSWER: There are two types of connections on a keg (what the bottle filler connects to) one is a pin lock the other is a ball lock. A pin lock has little pins that stick out of the inlet and outlet ports parallel to the floor. So you have to see if the person you are buying this for has the pins or no pins on their keg.
    Even having purged the bottle so as not to introduce oxygen to the beer when filling, do you not introduce it as you withdraw the bottling straw?
    A shopper on Jun 22, 2017
    BEST ANSWER: You will never completely eliminate all oxygen. The goal with here is to reduce the amount of O2 that touches the beer as much as possible. Lately I've stopped using the purge function when filling bottles and haven't had any negative effects.
    Can i bake the last straw in the oven at 350f to sanatize?
    A shopper on Mar 17, 2017
    BEST ANSWER: I'd say no also. A spare keg with cleaning solution is the way to go. Another nice trick is to go to your local hardware store and pick up a 22-inch wallpaper water tray. The size is perfect to give your last straw a sanitizing bath. However, nothing beats actively running sanitizer through it to get the inside sanitized. Fill the first bottle with sanitizer, switch to beer keg, fill second to flush sanitizer, start capping on your third bottle.

    Is the Last Straw only to be used to fill beer that is already carbonated (i.e. Beer was in keg, force carbonating for a few days, then pressure turned down to the suggested serving pressure and transferred to bottles) ?
    Or can you use the Last Straw to carbonate beer as you are bottling (i.e. Transfer beer from secondary to keg, seal, adjust both CO2 lines to suggested serving pressure 8-12psi, and fill bottles/cap) ?
    N G on Jun 3, 2016
    BEST ANSWER: I don?t think this will work. Think about it this way, if you transferred to a keg from secondary and then immediately pressurize and tap the keg, the beer would not yet be carbonated, that is essentially what is suggested here. The beer first needs to be fully carbonated because all you are really doing with the CO2 at the time of bottling with the Last Straw is pushing it out of the keg. Even in the breweries, finished beer takes a day or more to carbonate in a brite tank. That said, if you are bottle carbonating with sugar, you could do what is suggested here as long as the bottling sugar is introduced into the keg when transferring the finished beer.
    If I wanted to use a keg as a bottling bucket for some still mead would this work or would it carbonate no matter how low you turned it down?
    R Y on May 2, 2016
    BEST ANSWER: Over time the liquid in the keg will absorb CO2, but at low pressure it will not absorb quickly, so it really depends on how long you plan to store it under constant pressure.

    If you plan to bottle immediately, it will not be an issue at all.
    Can this fill 16oz bottles?
    K O on Apr 28, 2016
    BEST ANSWER: Yes it can. It also fills 22oz. bottles, Andit also fills 32oz bottles that i got from a case of beer that i was very happy to empty. I think this tool The Last Straw is the single most valuable tool i have bought since i started brewing in 2010.
    How do you go about sanitizing the hoses and device before using?
    David C on Mar 12, 2016
    BEST ANSWER: The best way to sanitize The Last Straw would be to put some santizer in a keg, and run it through The Last Straw using CO2 pressure. Basically like you would run beer through it but with sanitizer solution. You can also do this by running santizer through it using gravity feed. I hope that this helps!
    Would it be possible to split my co2 supply via manifold then connect the manifold to the last straw & keg. Set the regulator between 8-12 psi and bottle away?
    jesse r on Mar 10, 2016
    BEST ANSWER: That should work just fine - I actually pressurized an empty keg and connected it to the last straw as a co2 supply if you are trying to remedy only having one regulator line. I had to repressurize the keg a couple times during the process, but that was not a big deal just switching the gas line from the full keg to the empty keg.
    Dan L.- Bottles were cold, but not as cold as beer. I tried bottling the same way I did with Blichmann Beer Gun. Didn't chill lines, but never did with beer gun. Hoping to figure out problem, the Last Straw is much easier and you don't have to worry about rubber tip falling off. Just need to figure out foaming issue.
    J A on Feb 28, 2016
    BEST ANSWER: Try turning up the pressure a little bit. I had a foaming issue on the first couple of bottles at 4PSI, I bumped the pressure up to 8/9PSI and then there were no problems.
    Brand new to all of this so here's my newb question: What's the difference between the ball lock and the pin lock connection? Is it just a difference as to how this device connects to the co2 can?
    J H on Jan 16, 2016
    BEST ANSWER: Yes. It is a matter of how the plumbing attaches to your keg system. Seems to me that the ball lock is more popular but l don't know that for sure. My Cornie keg system uses the ball lock system and works well. Have had two successful bottlings with the Last Straw using the ball lock version.
    After filling the bottle and capping, how long does the carbonation last?
    E P on Nov 10, 2015
    BEST ANSWER: Assuming your cap has a good seal, indefinitely. Once capped, the bottle will keep the same amount of carbonation until opened. When bottling from a forced carbonated supply, you will loose carbonation continuously until you cap. The key is to cap right after filling to minimize losses. This differs from bottle conditioning in that when you bottle, there is no carbonation introduced yet, only a sugar solution for remnant yeast to consume which builds up carbonation after capping. The main difference is that bottle conditioning will increase carbonation over time and forced carbonation will maintain the same level as when capped.
    Where is the "Last Straw" manufactured?
    D A on Sep 4, 2016
    BEST ANSWER: works very well well worth the money strongly suggested if you are considering a bottling or if you want to bottle for mom you're a keg still on the way to go very functional
    Can it be used to fill a growler? Is it long enough?
    R W on Aug 14, 2016
    BEST ANSWER: Rich,

    Thanks for the question! Yes the Last Straw will work to fill growlers as well as bottles.

    Can the Last Straw be used for bottling from a sanke keg? The images and product video show the product using corny/soda kegs.
    H U on Aug 11, 2016
    BEST ANSWER: Sure - CO2 line in is pushing the beer out of the keg just like usual, and then instead of a tap line out, you are going to the wand. You will have no problem with a sanke.
    CO2 is bubbling out of the tip in the bottle and causing some foam. Know what is causing that?
    A N on Aug 6, 2016
    BEST ANSWER: It sounds like the co2 button could be sticking and not shutting all the way If you have some food grade lubricant you can unscrew the co2 button and lube it up a bit. If that doesn't work, please let us know.
    Is there somewhere to get spare washers for it? I know the washers are needed, and have managed to lose a couple , is there somewhere to get spares?
    J A on Jun 6, 2016
    BEST ANSWER: The part you are looking for is called a Flared Nylon washer. You can search for this by name or the product number K127.
    Can you use this product with Nitrogen gas or is it intended strictly for CO2 use?
    K E on Apr 20, 2016
    BEST ANSWER: If your beer is conditioned with N2, then there's no reason not to use N2 with the Last Straw to bottle the beer.
    Is this products hose long enough for a 5 gallon batch?
    K I on Apr 9, 2016
    BEST ANSWER: Hello Stephan,

    Thank you for choosing Northern Brewer! All of the components included with the Last Straw bottle filler will work to bottle out of a keg for any size batch. Just hook it up to your CO2 cylinder, and keg, and bottle away! The length of tubing will not differ from batch size to batch size. I hope that this helps, let me know if you have any questions!
    Can I bottle straight from secondary (70 degrees or so) to keg in the same day or do I need to cool the keg below 65*. My friend says that room temp would be to warm.
    Y A on Mar 25, 2016
    BEST ANSWER: Hi Mike,

    You would need to have the beer kegged and carbed in order to bottle with the Last Straw; you won't be able to do it directly from the secondary. You'll also need to allow the beer time to carbonate in the keg. You can force carbonate at room temperature, but this will require a higher psi, since gasses do not absorb as easily into liquid at warmer temps.

    Let me know if you have further questions!
    Is it possible to use Last Straw for filling not carbonated beer from fermenter and without connecting it to CO2 source? E.g. place fermenter above working area and let beer flow under "normal gravity " pressure.
    S A on Mar 2, 2016
    BEST ANSWER: For that, you'd be better off using an autosiphon with a bottle filler attached:

    I had tons of issues tonight trying to use the Last Straw. I tried bottling two different beers and both had excessive foaming in the bottle. I released the pressure in each keg prior to bottling and set the psi to between 4-6 psi. I could not fill a single bottle after trying 6 bottles on each keg. Neither keg was over-carbonated. Will it work better at the higher recommended psi of 8-12? I was really excited for this thing, but I am now really discouraged. Hopefully, it was my fault, but when I used to Blichmann Beer gun in the past I could always overcome foaming issues. Hoping to figure out the problem because this is much better built than the Blichmann Beer Gun.
    J A on Feb 28, 2016
    BEST ANSWER: Try chilling your bottles and lines to the same temp as the beer. Once the beer hits warm glass or lines the C02 will come out of solution causing excessive foaming
