I totally agree on everything you said, but if I understood it correctly, he is using RO water and that shouldn't have high alkalinity, am I correct? That said, taking care to adjust pH may be beneficial even when using RO water.

If you do not see evident darkening, I would wager that you are not experiencing blatant oxidation. I'm also of the opinion like other posters here that your problem must be more "basic". Steps like purging the headspace really only help in polishing the last details so to speak (I was active...

I just skimmed the thread so apologies if I missed some relevant information on your process and/or outcomes. Does your beer turn out darker than you would expect? If yes, this is a clear sign of post fermentation oxidation. If not, there may be other causes to your problems, at least in part...

Alright, you have got one of the experts I was talking about right here. Thanks @Silver_Is_Money for saving me, I am more than happy to leave the space to you :) He has helped me immensely with those formulas and other infos in a thread I had started on this subject long ago.

Yeah go for it if you can. It is probably the wisest and safest route indeed. I mean every situation is different. We are fortunate to have very good quality tap water here (no chlorines in it, for instance). So my only concern in that respect is having to deal with generally high and...

I think it all depends where you live. As I understand most of you guys in the US have very easy access to RO water and at comparatively cheap prices. It is not the same where I live. So the only economical alternative for me to use RO water would be to buy and operate a RO system at home. I...

Unless you have some fairly extreme levels of the one or other mineral in there, my first and foremost concern would be to know the alkalinity of your water (which is generally related to water hardness, i.e. the harder the water, the more alkaline it will be). This is by far the main water...

As an additional point, that I think was not mentioned here yet (otherwise, you already got a ton of useful info from the posters above). You should also try to find out whether you can trust that water report you will get. I mean, try to find out whether the composition of the water flowing...

The opening, yes the opening! It is our last resort when all blankets fail. Glad I changed from buckets to Speidels some time ago. But I'm not ready to go the "stainless + crazy O2 free dry hopping contraption " route yet.

I'm unsure how reputable a source Wikipedia is, but how would one explain the Lake Nyos dysaster? If it is false that CO2 at least TEMPORARILY sinks because it is heavier, then did this happen just because of the sheer amount of CO2 released all of a sudden by the eruption? So in this case, the...

Thanks, makes sense. I might try to keep one mineral water or soda bottle in my cellar and come back here in 10-20 years to report my observations ;)

So I have a question for the experts on gas physics here (maybe a stupid one, or one that has already been answered X-times in this forum before…apologies if that’s the case). If we assume, like it is often stated here and elsewhere, that bottle caps do not seal 100% airtight, and that some...

Thanks for the infos. Without having the time to delve into it much deeper for the moment, I really like the Soda Stream cylinder idea. I'll have to find out how or where to get one of those adapters here. It seems to me that you could easily rig it up as to handle the cylinder and valve with...

Very interested as well... No idea where to find CO2 equipment that cheap. So far I only stumbled upon those mini keg chargers...quite cheap but also relatively tiny amounts of CO2 in those cartridges. And no precise idea on how to put together a practicable device for purging headspaces. I...

Holy sheez I almost don't believe my eyes that even the half filled bottle is not yet showing some apparent signs of darkening...would then be interested to hear how it tastes compared to the rest... Concerning the too bitter taste. Although dumping all the trub in the fermenter may not be...

Please do post your results if you do this test! But I certainly won't delude myself by believing or hoping that the bottled version will come out just as good as the kegged one... 😉

You are absolutely correct, I only bottle condition so I cannot provide a comparison with the same beer closed transferred to keg. From what I gleaned from his posts, @tyrub42 might be the one who does both things. I seem to recall reading that if he has to bottle hoppy stuff, then bottle...

My post fermentation and bottling process is a bit unorthodox compared to other IPA/NEIPA bottlers that will do some sort of cold crash to settle hops and then bottle directly from the fermenter into individually primed bottles... You'll find all the relevant info on my process scattered through...

Just for the record, this is the last bottle of the same NEIPA as in post #230, but this time I had a chance at a direct sunlight shot. It is now 4 months post bottling almost to the day. Flavor-and aromawise it may not be what it was 2-3 months ago, but hell if it isn't hoppy still! I would...

Yeah I was first and foremost referring to alkalinity and the related pH control. That can have a huge impact if you happen to have high alkalinity water and do nothing about it. But now I remember also from that other thread you said that your water is good from that perspective. Mineral...
