  1. Tony Dos Santos

    This is probably my favourite mix. I do a 10% mix of this and it is absolutely superb.

  2. Paul

    What is the recommended steep time for this product? I’m yet to mix it, but I found the site very good all of my orders have been delivered within two days whatever method I have used.

    Wow!! 20% in 70/30 VG/PG mix takes me straight back to my Nan???s table. This stuff is goooood! 🙂

  4. George

    It just doesn’t get any better than this liquid and one I purchase time and time again, never tiring of the lushest flavour this concentrate delivers. (Mixed at 20% – 3 weeks steep) this flavour simply captures the sweet shop flavour of Rhubarb and Custard better than any others I have tried.

  5. Peter

    This has to be my favourite from the Alchemists flavours. Sweet rhubarb and creamy custard with just a hint of biscuit. I mix at 15% and it works brilliantly.

  6. JessVapes

    Perfection in a vape.
    Excellent flavour (mixed at 20% and steeped for 3 weeks) Its so good i cant put it down, my only quibble would be, to me, it tastes more like the hard boiled sweets than a bowl of rhubarb crumble and custard. saying that, i wouldn’t change it for the world. Highly Recommend!

  7. Kelly12345

    Without doubt the best Rhubarb Custard flavour there is. Mixed at 20% this works fantastically well after a 2-3 week steep. Full flavour that lingers. All round fantastic flavouring for vape liquid.

  8. Amir

    The best Rhubarb & Custard Vape in the UK, In-fact…. these guys are the probably the best “One-Shot E-Liquid” makers in the UK. Great selection and ridiculously flavourful.

  9. Sam

    Great flavour. good balance of all 3 key ingredients. 5*

  10. Darren

    Thoroughly enjoyed every drop of this liquid. A lovely smooth flavour. 5*

  11. Robbie G

    I love rhubarb & custard sweets and this mimics them well for me. Good mix for me is 20% @ 70/30 which i find doesn’t burn out coils quickly and delivers a long lingering flavour.

  12. Carol

    Old but Gold flavour, not one i buy very often but when i do, only the TAC’s rhubarb & custard will do. Ages very well, most 250ml i make last a good year, as its a once a week kind of flavour for me, goes perfect with a gin. 5*

  13. Mark

    Excellent, captures everything about a fresh baked Rhubarb pie with custard.
