    Immersion chiller

    I'd say most of that ground has been covered here. I mentioned "disturbance of laminar flow" i.e. "turbulent flow", although I admit I was referring to the coolant rather than that which is to be cooled. Agitation of the hopped wort is, as far as I can tell, a given if you want to improve...

    MY POSTS HAVE GONE DOWN?

    Fortunately we have the "Joined Date" to the minute so we know how long people have been here for lol.

    Andy Gray sacked .....

    It isn't just about offence. Plenty have kept their jobs whilst causing offence, be it Clarkson, Boyle, or AA Gill calling Clare Balding a "dyke on a bike" whilst keeping his job, it's about the various standards we expect to be upheld in the public image. Misogyny is, whether you agree or not...

    Andy Gray sacked .....

    I think time and place. Personally, I could see the humour in the original pic but it had little context, little to assure me that it was made in jest and was nought but a snipe at the vehemently held beliefs of a (hopefully increasing) minority of society. As an aside, I love post-PC humour...

    Boiler built!

    Basically bad electrical joints are like bad plumbing joints except you can't immediately see water pissing everywhere.

    Immersion chiller

    I'm pretty sure similar discussions have been had, hence my comment about triple coil chillers. The issue is that if you cool 90C hopped wort with 15C water it won't take that long a pipe for the coolant to acquire all the heat it's going to. Having more pipes of smaller bore won't necessarily...

    Immersion chiller

    Don't normally use wikipedia but http://en.wikipedia.org/wiki/Specific_heat_capacity "the specific heat capacity, often called simply specific heat" Guess it depends where you were taught your thermodynamics?

    Immersion chiller

    I'm sure I've seen a triple coil immersion chiller here or elsewhere (I don't think I dreamed that one) which was found to be no better than a double coil in practice at cooling 25 litres. Also the smaller bore will (as I suspect you realise) increase surface area of a volume of water, but that...

    Another pot size question

    This was an idea I seem to remember floating a while ago but can't seem to find it now... There's a calculator here: http://www.rackers.org/calcs.shtml which from my reading of the source appears to add 0.67 to the water:grain ratio (in litres:kilos) and multiply that by the weight of your...

    Andy Gray sacked .....

    This. To those who complain about footballers' salaries, look at that! Bananas! As it is Keys, interestingly, resigns. Almost like the Dark Lord Murdoch saw the conspiracy theories over Gray's suing of the NotW/his demise and thought well Keys needs to go now too but can't be sacked...

    Another pot size question

    If you were worried about the dead air above a mash in a mash tun, don't be, it doesn't have a great thermal capacity so won't change the ability of the mash to hold a temperature, just be sure to fully pre-heat the tun, as you'll be adding less liquor to strike with. The only worry might be an...

    Are cornies any good?

    In terms of conditioning, if you're using priming sugars then most of the fizz will be there after the first week or so, much like it takes a week or so for a (usual) beer to ferment. So you still have to wait for the beer to mature in terms of flavour so it doesn't taste as "green" (assuming...

    Heat Exchange Plate Chiller Info please.

    I think it needs some form of nitrogen and hot break is I think mainly nitrogenous proteins. You won't get it all out of solution though and using a plate chiller you'll get the cold break in the FV if you want it.

    What you reading?

    Anyone got a kindle? With out of copyright classics going for next to nothing (i.e. complete works of Shakespeare for less than a quid, Dickens etc) it almost seems like a good deal. I saw a bloke on a plane recently with one and the screen looked really good, not very reflective so a fairly...

    A Blended Whiskey & its bloody good too.

    I've been fortunate enough to try Blue Label and it's easily one of the best things to pass my lips. Blends can be great, you may consider that they lose a certain "individuality" in the blend, but then again they may gain their own in it. If they're notably cheaper than a single malt then it's...

    s-04 or kit yeast

    S04 also comes in sachets around twice the weight of the supplied kit yeast and likely enjoys a higher percentage viability.

    Yeast attenuation

    Simply put, different strokes for different folks, some strains are more able to ferment the dextrinous sugars than others, for the same reason a spaniel looks different to a labrador. Even dextrins are fermentable (just not very), that's why it's easier to leave a high OG beer to bottle...

    How to calculate ABV

    Yeah Van der Waals radii and all the chemistry I wanted to avoid. I guess it depends upon your view of significant (given below average hydrometers, temperature corrections often ignored etc there are plenty of other places for errors to creep in). I gave up calculating abv to any more than 1...

    Recommend me a AG book please.

    IMO Wheeler covers more than just "the basics" and is a good foundation without confusion. After reading that, this forum and doing a couple of brews you will have the crucial ingredient in a brewer, experience. For value for money John Palmer's How to Brew is a great resource (albeit...
