New Year's Mead

As not much is posted on this thread for mead, if you are a mead fan here is an offer you cannot refuse. Up for grabs are 10 bottles of mead of 25,50 and 70 CL which will be sent at no cost to those who plead the best story of why I should send them a bottle at absolutely no cost. All that I ask is ...

Re: Gardena Garden Hose - disaster or a subtle new dimension?

The hose will be plasticised PVC and the plasticiser will most likely be either DOP or DiNP, both of which are ortho phthalate plasticisers. If the hose is more than 15 years old it is likely to be DOP. In either case it will not kill you and unlikely to harm you. Plasticiser will migrate over time,...

Re: RO water filter

The reject rate for an RO is a function of the mineral ,loading AND the water pressure. For water to permeate through the membrane requires the osmotic pressure to be overcome. As the mineral loading increase so does the osmotic pressure. If you have a low mains pressure then there will be a very hi...

Re: Brewing liquor question

I will chip in my two cents worth but do not want to get embroiled in a pointless discussion. Several observations. You have a very thin water, which will be lacking any buffering in its delivered state. Calcium carbonate is sparingly soluble in water- typically about 40-50 mg/L depending on the oth...

Re: Plugging a 1" BSP hole

Be careful here. Make sure that the flange has an o ring groove otherwise you are likely to find that the ring will squash out. A Groove will trap the o ring in position. The other option, one I have done many times, is to use a Dowty seal, preferably a stainless one. https://www.ebay.co.uk/itm/DOWT...

Re: Can alkalinity be too low?

Guy, I do not think 16ppm vs target of 20 ppm is going to make much difference. Test kits are never super accurate so your 16 might even be 14 or 18. When you are getting to the extreme end of the range it is always a little tricky. When you get to 20 ppm alkalinity there is not much alkalinity buff...

Re: Cleaning and Domestic Drainage

Starsan is phosphoric acid and DDBSA. It will not have much effect on the septic tank system. If anything the phosphorous will act as a nutrient and the DDBSA will biodegrade without any adverse. I would switch the VPW to PBW, since the latter contains sodium percarbonate which will very quickly deg...

Re: What do you think this is, floating on boiled water?

I am pretty sure that as per the other posters your scum on the surface is limescale a.k.a. calcium carbonate.Your water is hard but far from ultra hard. When you boil the water the bi-carbonate (soluble) will decompose and precipitate as calcium carbonate. I suspect that the vigorous boil is not al...

Re: Beeswax - influence on mead fermentation?

You were lucky with your cappings; they are much wetter than what my wife produces. She drains the cappings to avoid too much give-away. I have so far about 24 buckets of cappings to deal with from about 900 kg of honey produced this year. At 1.1080 I would reckon your mead will be fairly dry and yo...

Re: Water analysis by Wallybrew/Pheonix analytical

I would not be too hard on Murphy not being able to determine sodium content. Sodium and Potassium are not particularly easy to determine, and require the use of a flame ionisation spectrophotometer i.e. high cost. Nitrate and sulphate are also not that simple. I would consider a fee of £26 for the ...

Re: Apples for making cider

It's a bit of a drag but you will find apples for free in your local area if you look hard enough. Often the owner is glad to get rid of them. Ideally you need a mix of cookers and eaters. All eaters will result ins a cider without much bite. The cookers have more tartness due to malic acid and this...

Re: Beeswax - influence on mead fermentation?

The wax will not affect the fermentation but it will be a pain in the ass at racking time. I use a filter bag to wash off the honey from the cappings. These are available cheaply on eBay. A 100 micron bag works well. I add the cappings to the bag and then pass warm water through the cappings into a ...

Re: Metheglin or poison

What honey did you use? Chestnut honey can be pretty awful with off tastes. Most of my mead comes out on the dry side, but still very palatable. Newcomers to mead expect it to be sweet, but the yeast will ferment to about 16% alcohol so to achieve a sweet mead you really have to load up the sugar co...

Re: Kindest sterilisers on septic tank system

Jeyes Fluid is based on p-chlorocresol and rar acids whilst Dettol is mainly chloroxylenol. This probably does not mean too much to most people. What these two products have in common is some chlorine and and a ring structure in the molecule, making them quite stable not not readily biodegraded . Th...
