Spundit V2 vs Blowtie Full Comparison for Homebrewers

[@ShortCircuitedBrewers]

The most thorough review of any of these products I've ever seen! Nice job David! 👍🍻

[@DavidHeathHomebrew]

Many thanks Brian, much appreciated :)

[@zzing]

Another thing that one can do is attach more evabarrier onto the end of the blowtie and use it as a blow tube in santizier.

[@DavidHeathHomebrew]

Thanks J. Yes for sure :) Plenty of options that are easy and cheap :)

[@Dev-sq1ym]

Thanks for the "half turn once fermenting" comment, I wasn't sure how to calibrate and didn't want to explode my closet

[@DavidHeathHomebrew]

Glad it helped 🍻🍻🍻

[@EmmetFurey]

David you are an absolute wizard and your channel is top notch!

[@DavidHeathHomebrew]

Many thanks, much appreciated :) I have had a real journey on the video making side since starting KZbin some years ago.

[@paskrell]

5:40 when pressure fermenting in plastic fermenters I usually pressure test and dial the valve in in one go. But definitely a great option ! Great video!!!

[@DavidHeathHomebrew]

Yes, me also. In fact I advised people to do this in my pressure guide :)

[@alanman5328]

Another fantastic factual comparison that actually made me want to buy both of these products due to their variety of features vs price. I had not heard of the spundit before this video and I have been looking at getting a couple of spunding valves, so this was very eye opening. Thank you David, your videos are so helpful.

[@DavidHeathHomebrew]

Many thanks Alan. Yes, the Spundit is not as well known as the Blowtie and hopefully this video will help raise awareness of it for consideration.

[@SimpleHomeBrew]

Nice, I use the blowtie as it is the most maintainable and cost effective item available for pressure fermenting. Thank you for reinforcing my confidence.

[@DavidHeathHomebrew]

Great, thanks for sharing :)

[@ollieberridge6117]

Great video David, love your work. I have been using both of the "kegland" blow tie models now for about 18 months with excellent results

[@DavidHeathHomebrew]

Great, thanks Ollie. Yes, they work very nicely, that is for sure :)

[@paulmcminn2802]

Another excellent and informative video David. Your videos give me the confidence to keep trying new brewing techniques and I thank you for them. Please keep them coming!

[@DavidHeathHomebrew]

Great to hear Paul :) More coming :)

[@fgoulding]

I have both a blowtie 1 & blowtie 2 but I use the B1 the most for pressure fermentation. However, I use the same type of ball lock connector that comes with the Spundit 2 because the right angle means I need less head clearance in my fermentation fridge. The B2 is really flexible and I remove the pressure gauge to use it when I’m filling my kegs.

[@DavidHeathHomebrew]

Thank you Fin. Yes I like the right angle stainless steel type myself. Yes, all good :)

[@NikitaVorontsov]

I use the Blowtie V1 and found it really useful! Only difficulty lies in not over tightening! Ive woken up in the morning to pressure off the scale with the PRV forced open. Power of Kveik!

[@DavidHeathHomebrew]

Many thanks for sharing Nikita.

[@SimonJD1000]

Worth noting that the Blowtie valve (at least, don't know about the other one) use 5/16 tube fitting, so if - like me - the rest of your gas line, adapters and fittings are 3/8, you will need to invest in a selection of 5/16 size equivalents and any necessary reducers to join everything up.

[@DavidHeathHomebrew]

All of the blowtie products are available in kit form which includes everything you need to attach via a bull lock. This is the easiest and cheapest way 🍻🍻🍻

[@GreySectoid]

I have the blow out valve type, I think I'm going to try to mark the desired psi on the screw with food safe marker pen, probably not as accurate but will give the ballpark when I'm taking it apart for cleaning.

[@DavidHeathHomebrew]

🍻🍻🍻

[@karlis6235]

I have the blowtie v1 with 4 bar range, never used it above 2 bar, though. It works great, makes a sound while fermenting and I see no need for the bubblers. The pressure is accurate and I see no need to spend more $$ on these thingies. It is also the most lightweight and compact. Great channel David, you have helped me a lot with your videos! :)

[@DavidHeathHomebrew]

Thanks for your input, much appreciated :) Great that you are enjoying the channel and finding it helpful.

[@timheffernan3577]

I use the Blichmann Spunding Valve and have been happy with it so far.

[@DavidHeathHomebrew]

Thanks Tim, this is not one that I have tried.

[@timheffernan3577]

@@DavidHeathHomebrew It's the only one I've tried. It was tri-clamp mounted so this fit my unitank but I haven't tried others so it's hard to say how it might compare. I have found your video's informative and helpful and really appreciate your product comparisons and overall reviews. I'm going to be testing a new approach to monitoring specific gravity and will let you know how it goes.

[@DavidHeathHomebrew]

Great to hear Tim. I look forward to hearing back on this new approach.

[@Nefariousrouge]

The tee piece is also helpful in setting up the valve pressure. Charge the bottle with 1 port and adjust the valve in the other. You don't waste a ton of co2 charging a keg to set the pressure. Pop it on the fermenter and you are good to go!

[@DavidHeathHomebrew]

Yes, for sure. Handy stuff all round.

[@kwm2136]

This .... is how I do mine also. Damn near perfect way to do so.

[@DavidHeathHomebrew]

Great :)

[@rmcphers]

sorry for not picking up but ..... what do you mean, setting up the valve pressure? do you mean for zeroing / truing it against known tank pressure?

[@Nefariousrouge]

@@rmcphersthe previous ways of setting the desired pressure on the valve would be to wait for a brew to develop enough co2 to pressurize the fermenter, and then it is trial and error to get it where you want. And it may effect the presbprocess. Alternatively you would pressurize a keg and adjust the valve. That method wastes a lot of co2. Now put this on a small 16/20oz soda bottle, and you only use a small about of co2 to pressurize and set the valve. Slap it on the fermenter and it is ready to go.

[@kenfowler1980]

I have several of the original Kegland ones - they work! I have even modified one for testing gas line pressures. The only complaint is they are bulky

[@DavidHeathHomebrew]

Great to hear Ken. Yes the small versions are certainly easier. I am looking forward to the digital blowtie. Great accuracy and small. Cheers 🍻

[@BitterRealityBrewing]

Excellent and informative as always. I have two of the kegland spunding valves with 15psi, 23 psi, and a spare 60 psi gauge. I also have a SPUNDit 2.0 and love the quality and I'm a bit accident prone too (your comment about being butter fingers) and have dropped all at least once without issues although the SPUNDit 2.0 did hit my foot which was good for it and not so good for my foot but no big deal. I agree with you as they all have advantages.

[@DavidHeathHomebrew]

Thank you, great to hear. Sounds like you have a good selection of these :) Good to hear that the Spundit survived its drop. I am going to try to find something to protect the gauge on mine. Yes, lots of pros and cons.

[@BEERNBBQBYLARRY]

I don't have a Blowtie, but I do have a Spundit. I really like the auxiliary port. It helped me ensure a consistent pressure across two fermenters concurrently which was cool. I might give that Blowtie a try as well. Thanks for the video!

[@DavidHeathHomebrew]

Great, thanks Larry. Both work well, different twists :)

[@HighVoltageBrewery]

@@DavidHeathHomebrew Just thinking, would it not be easy enough to do with the Blowtie as well? Thinking that we (yes I have Blowtie), from the Blowtie inlet, have a bit of tubing going to a tee piese, then 2 tubes to 2 fermenters. I have not tried it, because I don't have enough space for 2 fermenters in my fementer chamber.

[@DavidHeathHomebrew]

Yes, though you are just working with blown off pressure with this route. Having said this two blowties is still cheaper than one Spundit of course. It depends on what you are looking for.

[@geoffdickinson1310]

Hi David, once again, a great video. I have one query though. I have a Blowtie from KL with the Soda bottle adapter on a bottle to be a bubbler of sorts to give me indication of fermentation activity. I have mine connected in a very similar way to how yours is displayed in the video. With my set up I have had to fit a ball lock connector onto the third outlet of the Soda bottle adapter so as to allow the C02 to escape and not pressurise the bottle. If the ball lock post is left without a method for the gas to escape it just pressurises the Soda bottle. I hope you may understand my description or maybe I have missed something in how yours is set up. Cheers.

[@DavidHeathHomebrew]

This has always simply worked for me, yours is the first comment of this type. Could it be that you have the bottle fixed super tight?

[@geoffdickinson1310]

@@DavidHeathHomebrew yes David you are correct. The bottle is tight on my set up. I use a ball lock fitting to release the gas but I can also fit another tube to that ball lock and use the C02 to purge another keg etc.. My apology for going off on a tangent from the Spunding valves.👍

[@FermentationAdventures]

I had the blow tie 1, and it leaked under from the dial gauge. Can’t be terribly uncommon since the retailer had some troubleshooting steps ready to go and refunded me with little hassle when I still had issues. I went with blowtie 2 instead and no issues.

[@DavidHeathHomebrew]

Great, thanks for sharing :)

[@brewbeer1013]

Great video, I keep stressing in my videos the importance of using Food Grade equipment. Iv seen all sorts on youtube using all sorts of non food grade materials and it makes me wonder what chemical leaching if any is taking place. Especially at higher temps. Cheers 😎

[@DavidHeathHomebrew]

Thank you. Yes, it is certainly very important that people get the right information. Many thanks for your message :)

[@leiflindqvist9095]

Blowtie to is the choice for people that prefer a bit higher pressure....like 2,3 bar for more carbonation. To get rid of the initial pressure fiddling it's a good idea just to fill co2 to your preferred pressure and tune the spunding valve accordingly.

[@DavidHeathHomebrew]

You can use both that way in all honesty :) Yes, I suggest people set up their spunding valve whilst doing the pressure test. Two birds with one stone :)

[@pdubb9754]

I've not spunded any batches yet. I own what I believe is one of the cheap spunding valves that probably is the path to frustration, based on your comments. Once I give that a try and am dissatisfied, I think I like the kegland models. Seems easier to clean.

[@DavidHeathHomebrew]

Thanks for sharing. Yes, not only are they frustrating they can also end up ruining things.

[@chrisb5839]

Hi David, very new to homebrew and thinking of switching from a pressure barrel to a PET keg. Can you use these blowtie valves as a pressure regulator to put gas INTO the keg i.e. via a soda stream tank, or do these only regulate the pressure inside the keg by letting gas OUT? 🤔

[@DavidHeathHomebrew]

Actually no, that is the opposite. For this application you need products like these:- kzbin.info/www/bejne/p5i4pn2ogpWardUsi=eyfK34ZXkxSskkRE

[@AM2PMReviews]

I’ve taken apart my blowtie after one transfer and it seems to no longer work properly as a sounding valve. I keep cleaning it and reassembling it just to make sure but maybe something is wrong? Did you ever have any issues with the little blow tie not working? Maybe he diaphragm is clean but somehow sticking

[@DavidHeathHomebrew]

Thats odd, no ive not had any issues like that, nor have I come across this. Perhaps a short clean with a PBW would work. Keep it within 10 mins max.

[@AM2PMReviews]

I will try that. What is PBW made with? I was cleaning kegs with sodium metabisulfite...is that similar? @@DavidHeathHomebrew

[@joeby13]

Hey David. I’m using the blow tie one version in your video. I currently have a beer fermenting under pressure and have gas bubbling away through the blow tie. However the gauge on the blow tie is still down at 0, I’m assuming I have a leak somewhere ? If I tighten the blow tie just a fraction it does stop the flow, so I’m confident the mechanism is working. Hmmm

[@DavidHeathHomebrew]

Sounds like a leak, or perhaps you need to make some adjustment. I would remove it and refit the tubing ensuring it is locked in tight to the duotight ends.

[@joeby13]

@@DavidHeathHomebrew thanks for the reply. I've taken it off and put it all back together, so i'll monitor that. To clarify does the dial move the needle on the gauge and you move that to set the psi level. Or does the needle move once it starts to get gas flowing into it?

[@DavidHeathHomebrew]

Great. The needle moves as pressure is added. Tighten the top to stop it going past the level you want, which is really best in general at 10-12 PSI.

[@alamokid9222]

Spundit v2 I can pressure ferment 2 vessels with no issues only using 1 valve for 2 vessels.

[@DavidHeathHomebrew]

Yes, true. This requires an extra and both vessels to be at the same pressure. Though for the price you can buy several blowties with digital displays added for even greater accuracy.

[@MikeS29]

Thank you for your excellent review.

[@DavidHeathHomebrew]

Glad it was helpful! Cheers :)

[@ashleym2878]

My sounding valve with built in guage is inaccurate by 5psi atleast that's compared to my keg king guage on my co2 bottle

[@DavidHeathHomebrew]

I would suggest unscrewing it and giving it a clean.

[@mardanheddeokwa]

Hi David, a very good video at a very good time :-) I was just looking at the different types. There is also a brass one on the market. Don't know how good that one is, but I think I will go for the plastic one with the separate gauge. Because of the cleaning. One question, normally it won't happen but what if a high krausen happens and the beer comes up. I think this does harm the gauge?

[@DavidHeathHomebrew]

Hi Chris, I covered the brass type in this video:- kzbin.info/www/bejne/hH2tXqSjnc14pLc

[@DavidHeathHomebrew]

In terms of beer reaching the gauge this can ruin them yes. The trick is to not have too much pressure at the start.

[@thebackyardbrewer5611]

You got the names for the blowtie units the wrong way around. The integrated pressure gauge unit is actually called "blowtie 2" by kegland

[@DavidHeathHomebrew]

I simply numbered them on screen in the order they appeared left to right for reference. There is no blowtie one or two. I did mention the release order elsewhere in the video though.

[@petedudley1]

Did you determine the oxygen permeability of the tubing used in the Kegland spunding valve? Their EVA barrier tubing is excellent in terms of low permeability, but I don't believe that's the tubing they use in their spunding valves.

[@DavidHeathHomebrew]

Thanks Peter. You can add whatever you like to it as long as you use the right size :)

[@petedudley1]

@@DavidHeathHomebrew Hi David, yep, that's right, but the EVA barrier tubing is flexible enough that the spunding assembly can bend out of shape and leak. The tubing that comes with it is stiffer but I'm not sure how it compares to the EVA barrier tubing in terms of permeability. Would be useful to know. I'll email Kegland

[@DavidHeathHomebrew]

Thanks Peter, yes Kegland would certainly be able to advise further on this.

[@fgoulding]

One question I forgot to ask - when using the spunding valve with the tee piece and bottle as a bubbler, how does the CO2 escape? Thanks!

[@DavidHeathHomebrew]

Hi Fin, I have it so that the bottle is not super tightly screwed on, so after a certain amount of pressure the air escapes. Simple yet effective.

[@fgoulding]

Perfect and many thanks for the reply@@DavidHeathHomebrew . I’m going to give that a go on my next brew :)

[@DavidHeathHomebrew]

[@horn8mech]

Do you know if the tubing from the Ball lock to the main body for the Kegland versions can be lengthened without adverse effects?

[@DavidHeathHomebrew]

If we are talking silicone here then yes but with some limitations of course.

[@TheGavranatar]

Thanks DH. Is a bubbler needed or can i just let the gas escape without worrying about infection? I have used the blowtie twice. I set pressure to 10psi with a keg, but both brews have crept up to 20psi when fermentation got more vigorous, is that normal?

[@DavidHeathHomebrew]

Thanks. No, the bubbler is an optional extra. That is not normal. You do need to “bed in” spunding valves for a few hours before the first use though.

[@nicobrandt3378]

with the carbonation cap tee and the bottle...it looks like the co2 stays in the bottle...wont that explode?

[@DavidHeathHomebrew]

Hi Nico, It actually does not. The trick is to not do it up tightly. Not that it needs to be loose either. Just enough that a little can escape. You would need do this up very tightly to prevent this and it is unlikely that would last very long anyway.

[@YouCanDoitHomebrewIt]

Hallow my m8👍. basically David im got🧠 confused with the new Kegland Blowtie 2 spunding valve. in the guage is says 15psi, with me so far? if i want to pressure ferment say your Munich Helles @ 25 psi, how can i work this problem? sorry you know my coms probs. ive sent you a friend request ( Grommit Knives) in FaceBook. Thank as always Brian 😎👍

Hi Brian, you will need to adjust it via the middle knob to change this. However, 10-12 PSI is a much safer place to be for yeast health.
