Re: Sodium Percarbonate

I've always gone for the pentahydrate, but mainly because it has been easier/cheaper to find in the past - such as from mistral - and (rightly or wrongly) I believe it to be easier to get into warm solution. Sadly I've no idea on how well the anhydrous version works in practice though; it may be bet...

Re: Storing Yeast Slurry in Bags... Would you trust these?

Even the general cleanliness would be a complete pain for me to achieve in my little kitchen, let alone the equipment or procedures! I must admit that I no longer attempt to keep yeast very long term these days (unless perhaps of a type that cannot easily be bought). A combination of splitting and h...

Re: Control Panel Parts List

You really need a more complete plan (of the whole controller) before purchasing anything, because these decisions tend to be related, but it is right to be looking at all the possibilities beforehand so certainly ask away. Standard mains surge protectors are usually only appropriate for unexpected ...

Re: Control Panel Parts List

There are different ways of doing such things and so you have many decisions to make. An STC (with relay/contactor) and timer could all be done quite simply at 240v, and would be my choice if that were the extent of it. However if you might be wanting additional (perhaps more sophisticated) controls...

Re: Control Panel Parts List

An STC or other thermostat would probably be my choice in that situation, I've done exactly this (also combined with a timer) on several builds and they are perfectly adequate for getting liquor to strike temperature. A PID would be great for control but would keep switching the expensive induction ...

Re: Heating a 200l fermenter

You probably won't need all that much power unless it is uninsulated and in an unheated room. My personal preference (for electric heating) is self-regulating trace-heating cable , but you can get it in non regulating types, or soil heating cable, or silicone or vivarium heating mats that cover a bi...

Re: Control Panel Parts List

Another question: Why do people use PIDs rather than STC 1000s to control the elements? Would STC 1000s not also do the job? Thermostats like the STC switch fully on or fully off the moment set temperatures are reached. There is almost always some delay in the system, so the actual temperature will...

Re: SS Brewtech Thread Size

Thanks so much everyone! I'll give the 3/8 a go, it's for the CIP so doesn't need to be perfect. Indeed. Though if the thread is 3/8" BSP as Lee found then still try to get 3/8" BSP parts to fit it; NPT isn't compatible in this size ('even' as a fudge) and may only go on a turn or so. Shouldn't be ...

Re: Glycol

Crikey, that puts these subtleties into perspective. I'd hate to brew to tight schedules and turnovers, must be quite frustrating at times.

Re: Glycol

Yes, there are lots of things that contribute to clarity and that go 'much' deeper into quality of the beer than aesthetics alone. To be clear (heh!) I'm not at all arguing against chilling - provided it is an addition to the process rather than an attempt to hide deficiencies earlier on. It is just...

Re: Glycol

Yes, chilling can certainly help speed up clearing, particularly with awkward yeast and chill haze; the closer to freezing (without freezing) that one can get the beer the better, in terms of speed. My change in preference has been more about 'when' to chill, rather than whether to. Chilling soon af...

Re: King keg pressure vavle

If there is excess pressure then the seal may be working as intended; that can occur when injecting a whole bulb into a small area of head-space. In that case then the valve should seal once pressure drops, and then maintain the normal levels. Sometimes after injecting, ice can form and the rubber c...

Re: SS Brewtech Thread Size

Just to mention, BSP and NPT are not compatible in most sizes; if the size is 3/8" nominal bore as Lee suggested then the correct type should be used. If they're 1/2" (or also, I think, 3/4") then the threads per inch happen to coincide, so only for these sizes NPT and BSP can sometimes be mixed in ...
