Bit light in colour given that I was trying to use "No.3 Invert". But I'd already dismissed colour as a motive to switch to this sort of stuff (from Porter) a few posts back: and I'd made a mistake when concocting my home-made No.3, I assumed that as I was starting with a No.2
coloured syrup I only needed 1 - 1.5 hours cooking to make it No.3: Bo11ocks, I was starting with the equivalent of No.1 (Golden Syrup) and it would take 2-3 hours cooking to get it up to No.3. The extra colour in my "No.2" base was due to molasses and the colours could compliment each other but not necessarily
add to each other. If the colours had mysteriously accumulated, the flavours wouldn't, so I would have had No.3 coloured No.2 Invert and probably confused and disappointed that it didn't
taste like No.3. I'll try Lyle's Golden Syrup next time (guaranteed cane sugar, perhaps, so no need to add molasses). Enough of that!
Made some invert sugar syrup today. Ragus, who make brewer's invert,
provide a lot of information on their site, although it is frequently updated and often difficult to find stuff you want to read again. Another danger is trying to make invert as they do, I learned that the hard way and advise anyone who think they have cracked it by trying to replicate what they do, don't, unless you wish to know what I made,
In Graham Wheeler's first book, Home Brewing, Chapter 5, Grain, Sugar, Malt Extract, is a simple method that does work. It might not make totally perfect inverted sugar, but doesn't require an hour and a half over a hot stove while producing a very acceptable product. He added 2 lbs of sugar to a pint of water, added a teaspoon of citric acid crystals and simmered it for a few minutes, then neutralised it with sodium carbonate.

Add a kg of refined cane sugar to half a litre of water while on a low heat and stirring. The sugar will mostly dissolve at about 70C, but the mixture will not be totally clear. Keep the heat low and add the citric acid while stirring. If the water is soft or RO or DI, a level teaspoon will be enough, but for hard water add a heaped spoonful and the mixture will clear. Inverted sugar is more soluble than sucrose and as the mixture begins to simmer, more sugar could be added and the liquid would remain clear. The mixture is then simmered for a couple of minutes when it will begin to show a light yellow colour and is ready to be neutralised to stop the process going too far.

When inversion is complete, Ragus add 5% extra sugars depending upon the grade being made to give the required colour and flavours, and for the solid version 10% dextrose is added.
I don't make the solid version, but do add molasses, blackstrap, Black Treacle, dark caramel, or just some soft dark sugar to give extra colour and flavour as required. as well as partially neuralising the added acid.
Tonight's finished product.
Without patience, life becomes difficult and the sooner it's finished, the better.
