    Mixed results
    At the time I received the Last Straw as a Christmas give I only had 2 kegs in the fridge. I tried bottling from both kegs (normally @ 11 psi). I dropped the pressure to 8 psi and tried to bottle. It was still excessively foamy. The next couple of bottles I dropped to 5 PSI and it was a little better (less foam) but a little slow to fill. I will need to try this a few more times before I can decide if this will work well or not.

    Really a nice solution
    This is a very well made, well thought out bottle filler. I've used it twice now and it's been very easy to manage. It's caused me to stop bottle conditioning completely and only force carbonate. The hidden benefit is that I can bottle some of a batch, then keep the rest on tap. Or, if my keg is almost empty and I need it for another beer, I can bottle the last bit. I highly recommend this.

    much easier than counterpressure fillers
    The last straw is a great piece of equipment. Counter pressure fillers are a pain in the butt. Having had a stroke over ten years ago that mostly took the use of one of my hands would make it impossible to use one without an assistant. I choose the Last Straw over the Blichmann Beer Gun due to the large number of 5 star reviews on the Last Straw. The Blichmann has a trigger that must be pulled to use it so I thought it would be too hard for me one handed. I've used the Last Straw 3 times with mostly good results. The first two times I bottled at 10 or 12 psi (my normal serving pressure) with only a little foam. I filled the bottles all the way to the top with no loss of carbonation. The third time I lowered my regulator to 8 psi. This caused more foam due to C02 coming out of solution.. So serving pressure works better. After sanitizing the bottles with Stat San (swing tops) I chill them in the freezer for 30 minutes while preparing the filler. Nice to be able to bottle beer right out of kegs. Very happy with my purchase.

    Perfect filler
    As long as the bottles/growlers are chilled this worked perfectly! Clean up is super easy. Just had a beer I bottled a month ago and it was great!

    Awsome product
    Had trouble at first with too much foam but found out I had a loose connection. After checking all connections and tightening it works beautifully. Usually will have a little foam on first bottle but after that, smooth sailing. If you stop to wash more bottles for several minutes you may get a little foam in your first bottle when you start back up. This thing really is awesome. I bottle at 12 psi with no issues.

    Very useful tool
    Works well but needs low co2 pressure on the keg that is being bottled. I keep this hanging on my brew room wall and it is very sturdy. I only use this when bottling a large volume of beer. I think it is a decent buy.
    June 29, 2016
    A cool piece of hardware, but it didn't accomplish the task for me.
    This product seems well built. It assembled and functioned well. The problem was injecting pressurize beer into an unpressurized bottle allowed carbonation to escape. So even tho the Last Straw displaces the air from the bottle it dose not pressurize it. The result was substantially reduced carbonation leaving the beer almost flat when it was opened later.

    Response from Northern Brewer
    If the bottles are chilled to near freezing, and the beer is well carbonated and quite cold also, the carbonation should stay in the beer as the bottles are carefully filled. You should cap the bottles immediately to retain the carbonation as much as possible. -Mike W, Northern Brewer

    My counterpressure filler works much better
    Tried this once so far, and bottle was half foam. Didn't want to try it with my limited kegs, but will try it again when I get more adventurous and don't care as much about the beer I'm filling.

    Can I buy a replacement spring?

    BEST ANSWER: While we do not have replacement parts readily available, our customer service team is always happy to help.
    How do i get more of the plastic ferrules for the hose connections?
    A shopper on Nov 28, 2016
    BEST ANSWER: We do sell extra Flared Nylon Washer (SKU# K127).
    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.
    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 F 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.
    A shopper on Jan 13, 2017
    BEST ANSWER: In inches, the dimensions are 24 X 4.5 X 2
    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!
    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.
    Can this be used with a beer under nitro?

    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.
    I'm wondering about the efficiency/necessity of purging, given that filling the bottle to the top with beer pushes out all the CO2 just introduced and then removing the wand re-introduces an inch or so of normal air before capping. So is the purging just to avoid a few seconds of air contact as the bottle fills? Has anyone tested the quality of purged bottles against unpurged?
    G R on Nov 25, 2015
    BEST ANSWER: The main idea there is the CO2 is heavier than oxygen so it does not push all of it out and still protects the beer against that oxygen. The main time that the beer is at risk of absorbing oxygen is as the beer moves its surface area exposed to oxygen is greater and the motion can cause oxygen to get absorbed. So by purging we prevent any oxygen from being able to be absorbed during filling and then since its heavier than air it stays in the bottle and no oxygen should get introduced when taking the unit out

    for the most part. The difference which is observable is that with out purging most beers only last a week or two at most before they start to degrade. With a bottle filler like this that should be more like 2-6 months for most beers. I hope this makes sense! Cheers! James J.
    Is Northern Brewer planning on offering a small parts kit, that might include a new spring, poppet valve and any gaskets that a user may need, or loose in the future?
    S N on Nov 12, 2015
    BEST ANSWER: I think NB should offer a parts kit. However, l can't answer this question since l can't make a business decision for NB.
    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.

    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!
