Re: CRISP CLEAR CHOICE ALE MALT

It just seems like any other malt, really.

Re: Beer engines; keeping it fresh

Beer liner cleaner usually has less than 5% of chlorine-based bleaching agent Household bleach bottles normally quote the same figure. Dunno, though the thought occurs to me that if someone walks into a job at England Worthside, they don't suddenly become an authority on chemical reactions with bee...

Re: Beer engines; keeping it fresh

I have also learned to my cost that bleach/chlorine can permanently taint the pumps .
It shouldn't be a problem with thin bleach but probably would be with thick bleach, which is intended to cling to surfaces. Let's not forget that pub cleaning fluid is chlorine based.

Re: Beer engines; keeping it fresh

I find I can drink from the beer engine after 24 hours without wasting any beer, at least in autumn, winter and spring. In summer, I'll throw away the first two pulls worth. This is in an unheated room. I clean with warm water dosed with thin bleach and washing up liquid (I've tried professional bee...

Re: Filtering Wine

I believe oxygenation is much less of a problem with wine than it is with beer. Look how winemakers 'whip' their wine to remove the CO2 - you wouldn't do that with beer.

Re: Beer cooler water treatment?

I would be hesitant with using a central heating corrosion inhibitor that is not fit for aluminium
Is there any aluminium in a beer cooler? Mine appears to be copper, stainless and plastic.

Beer cooler water treatment?

Is there a product sold specifically to treat the water in the ice bath of beer coolers? Mine has a thick growth of green sludge.

Re: Brite Tank Cooling with Maxi 110

I've been using the same beer cooler for about 15 years to control fermentation temp. I leave the compressor on permanently (controlled by the beer coolers own ice-stat)and my ATC 800 controls the recirc pump to manage fermentation temp. I can understand the concerns that the pump is also the agitat...

Re: Am I killing my enzymes?

Wanus, that's a very good question! I went to HERMS because I wanted to recycle and get crystal clear wort, to stop winter heat loss, because everyone else seems to do it and I thought I might be missing out and also because I like bodging new kit.

Re: Am I killing my enzymes?

"I have RIMS, but avoid recycling at the initial stages"

That's what I'm thinking now - do a conventional infusion mash for about 30-40 min, then start recycling after most of the conversion has taken place?

Re: Am I killing my enzymes?

Yes, it's the same tun and I am heating the water enough for the mash to settle at close to 66 after the grain is added. I'm tending to go for quite a thin mash, so I'd hope that channeling wouldn't be an issue, but how could I know? I'm batch sparging and I stir when I refill the tun.

Re: Am I killing my enzymes?

I'm maintaining 66c as the wort enterers the tun, about 1 meter of silicone pipe after the kettle.

Am I killing my enzymes?

After about 200 brews using a simple insulated mash tun, I've switch to HERMS for the last half a dozen brews. The main change I can see is a massive loss of efficiency, requiring about 30% more malt. My heat exchanger is a cheap 1.7 litre kettle with a copper coil for the beer to circulate through ...

I've used this a couple of times: https://www.themaltmiller.co.uk/product ... rity-15ml/

If anyone would like the remaining half a bottle, you'll be very welcome to it?
