    I could hardly wait to get and try the nitrous oxide diffuser after reading the account in the Telegraph.
    Having sloes in the freezer, I proceeded with them in the way you described. I was left with barely coloured sugary alcohol, with not even a trace of sloe flavour or colour.
    Undeterred, I put in a third canister of nitrous oxide, and left it for 20 hours.
    It made no difference.
    As far as I can see, the fizz is a swizz!

  2. … I awoke this morning thinking about this one.. sad I know Terry. But lastly, are you certain you are using Nitrous oxide and not carbon dioxide? I’m saying this as you say “the Fizz” is a swizz. There is not that much fizz with the Nitrous oxide.

    I cannot get the Flash plugin to stop crashing on my computer, so I have had to look at the video elsewhere, thus the delay in replying.
    I will address the points you raise.
    To start with, I used the standard proportions of gin, sloes and sugar,
    (1L, 450 grams, 125 grams). The actual amount I put in did not fill it, so for the 3rd gas cylinder, I added extra sloes, over twice the usual amount.
    Yes, it was the infuser shown.
    I did not prick the sloes for the first effort, but did for the re-do. As far as I can see, you did not prick them. I have now, after the tedious filtering, tried it, and it is hopeless, hardly any sloe flavour at all.

    Yes, I used nitrous oxide, the cream 24 as sold by the cream site from which I bought the diffuser.
    (They sell 2 sorts of nitrous oxide, but try as I may, I could get no idea of the difference between them, apart from price).
    The bubbles were minute. I tipped it all out into a jug so as to see what was happening better, and it continued to fizz for several minutes, very fine, as you suggest.
    Two more asides:
    I was disappointed to see no “Instructions for use” either on the site or in the package, apart from the mechanical instructions (fill it, charge it etc.).
    Secondly, I found a bumper crop of sloes 3 years ago, and picked so many that I decided to juice them with a steam extractor. This was brilliant, and produced the best sloe gin yet.

    I shall try the diffuser again next year, but as you can tell, I am sure, I am underwhelmed by the method so far.

    • Well, the plot thickens! I have to say I’m quite new to using the infuser and all I can do is repeat that it worked for me. Did you shake it? Perhpas that’s the last varible I can think of. Or even temperature, I spoke to scientist about this and although it wasn’t his field he said, “I suspect other gases or low boiling point liquids would also be useful in accelerated sloe gin preparation such as dimethyl ether or supercritical carbon dioxide”. But, that’s really an aside too.

      I hear you about the instructions. There were some on the website I noticed, but none when it arrived. I’d read around considerably before using so I guess I’d not really paid that much attention. Perhaps something you could take up with the company?

      I’d not heard of the steam juicer and have since looked around and well, it looks Terry as if you have sparked my interest in another gadget.

      As for the pricking, nope I never do I froze them and thawed them, actually I may have done that twice as my toddler switched off the freezer a while back. I did experiment earlier with some bigger victoria plums and got similar results as you suggest. I’m sure you know what you are picking and don’t wish to question that: but perhaps they were bullaces or damsons and not sloes?

      Anyway, thanks for sharing I’m sure it’s as helpful to my visitors as it is for me to hear the results when they don’t work as well as when they do! I’m rather gutted for you that you obviously wasted some sloes and some gin!

  5. Hi,
    We are the importer of the Soda Plus carbonator and infuser which Andy used to create the instant sloe gin. Not sure what people are doing wrong here – we use it all the time and its really easy to use. The website has detailed instructions on it:
    http://www.creamsupplies.co.uk/soda-plus-carbonator-infuser-1-2l-/prod_6932.html?category=3485
    Infusing is actually our idea – Mosa the manufacturer – are marketing it as a carbonator but we think the potential for infusing is much more interesting.. and fun!
