This subject set a bit of a hare running in my mind ... I think, but I'm not sure, that beer bottles have been brown since the early days of commercial beer brewing (anyone know?). So I'd imagine the effect of sunlight ruining beer has been known for a long time. That set me to thinking when...

Although I don't actually know the answer, applying a bit of science it's possible to come to a realistic expectation .... When the sun is high in the sky and on a very clear day then the total energy density across the whole spectrum is around 800W per square metre in the UK i.e. brighter by...

Not much chance of that, the lithium content will be too valuable & will be recycled. It's intriguing to see people expressing an aversion to technology on the basis of what seems like zero knowledge :confused: I'd be grateful if you'd explain it will be an excellent case example for my future...

No joke really because the answer is yes. (some brief info here but also see Tesla Battery Day videos if you have an hour to spare) It's the way to make cheapest & lightest EV, but of course may not be acceptable to the consumer & might fail on those grounds. But in the not too distant future if...

The vehicle market is very large and there are likely to be several competing battery fit methodologies. The argument is that the lowest cost & lightest vehicle structure would be to build the battery as part of the vehicle chassis. This is the line that Tesla is following & also supported (I...

This has to be the worst nightmare for Hyundai and for all BEV & lithium battery manufacturers really as it quite understandably undermines public confidence in the technology. Regarding battery lifetime much fear of short lifetime is based on mobile phone and computer battery lifetime. What...

The best thing really is to listen to this interview with Charlie Tally of 5 Star, he invented Star San so info from the horse's mouth. 03-29-07 Basic Brewing Radio - Sanitizing with Bleach and Star San from Basic Brewing Radio | Podcast Episode on Podbay Summary is that pH needs to be below 3...

I think that the conclusion would have to be theory unproven due to the lack of laboratory quality data but there is a very strong logical science based argument to say that continuous stirring is not a good idea and may actually be detrimental. Personally I plan to give the shake method using...

Sounds to me nothing like yeast pitching issues but a persistent bacterial infection in the fermenter. My vote would go with those who have already suggested using a brand new cheap plastic bin fermenter for a brew and see how it goes. Might be worth closely inspecting your fermzilla for...

I wouldn't doubt it and I guess that's the stock answer. The party line from 5Star is also that a fresh solution of Star San should be made for each sanitation run. However if you listen to the interview with Charlie Tally he gives the real answer. It had not struck me before but I am coming to...

Sacharomyces, please don't give up on us! I for one, have thoroughly enjoyed reading your replies & referred articles. Thank you for attempting to bring some science into the subject, something often lacking on this forum. I want to remain positive so I won't labour this point, but I'd rather...

Can't be 100% sure but I don't think that Starsan has a defined shelf life (true for diluted Starsan only if de-ionised water is used). I remember listening to a recorded talk by the inventor where the long lifetime of Starsan was mentioned. (worth a listen, Charlie Tally forward to about 52...

I use a counterflow chiller pumped with a magnetically linked pump on the hot side. Works fine but agree with comments about hop debris easily blocking pump. I use a hop bag & a hop filter which pretty well eliminates the problem. When cleaning after the brew I run PBW cleaner through the pump &...

I can vouch for the new AEB kegs from BrewUk, they are very high quality and currently their 2 keg starter kit is just under £260. The only thing I'd say is beware of the gas regulator in these starter kits. I do use one but I found these cheap regulators can't accurately regulate the lower...

To Sacharomyces Very interesting and persuasive arguments. Having read all of your comments and your Shaken not Stirred article what I'd love to see is a step by step 'how to do it' description i.e. take out all the argument, microbiological info etc and just concentrate on the practical details...

I'd thought about building some keg scales a while ago but my keg fridge is too small. As a workaround I keep a cheap tally counter (available cheap on eBay) for each keg and count each half pint. So when the counter is getting up towards 64 I know the Corny keg will soon be empty. It works...

If you are brewing on a budget then plastic is the obvious choice, but it's certainly not the ideal material for a FV. SS is far easier to clean reliably and has a very long lifetime. I got shot of my plastic FV after a couple of duff brews & found that the inside was badly scratched, probably...

My 50 litre brew kettle is non magnetic SS so I was interested to know if an induction interface disc might work. Came across this In-Depth Product Review: Induction Interface Discs: The Inefficiency of Induction Converter Discs (aka Induction Interface Discs or Diffusers) and What Your Real...

I watched Greenland on Amazon Prine the other evening ... turned out to be a very stereotypical disaster movie with up to date special effects. Can't say I'd recommend it unless disaster movies are your thing. I believe this genre of movies is quite 'popular' at the current time e.g. Contagion...

I'd second that. In fact I don't trust plastic at all for fermentation & storage, so wherever possible use stainless steel.
