- How to concentrate flavour in a vacuum at low temperature using the rotavap.
I demonstrate how I make a low temperature reduced rhubarb molasses in the Buchi rotary vacuum evaporator and how I use that in a signature dish on my menu.

Nice video Chef,
Yes please more videos like this.
Thanks very much, I have a few more banked ready to come out, some more techniques, fermentation and rotavap stuff and a couple of other interesting bits :)
Best channel for inovated cooking, it really open my mind, may i ask if Rotavap extracts all those fragance, how intense is it. Is it strong enough to mix with coffee to create some aromatic coffee
Hi Eddy, very interesting! Do you reckon you could achieve an almost powder-like reduction with the rotovap? Thanks a lot!
Could you please provide links to the equipment you're using? Specifically, your juicer, centrifuge, rotary evaporator, vacuum pump, and chiller? Thanks and looking forward to more rotovap videos. Would love to see how you make your scotch bonnet chocolate!
I have a 50L rotary evaporator for sale if you are still in the market
It’s a full set with vacuum pump and chiller made by Across International
what is the centrifuge equip brand
Centrifuge is the Spinzall @@kertse1
Buchi r100 rotavap, the chiller and pump are from Buchi too. The centrifuge is the spinzall centrifuge, full video about that coming soon
Holy moly this is inspiring. Im thinking about buying one rotovap for making stabel flavours for vodka. correct me if im wrong but then you would use the evaporated output right? Would you change the parameters to extract more flavor to that side in that case?
High, yes that’s basically it, I have a video about how I use mine to distil and make gin which goes into this in more detail and you might find helpful :)
Thank you for the great content Eddie! Could you recommend a book or online resource to someone who is just getting into using a rotavap?
I hope you will keep making these videos! :) :)
Hi, I have a couple more videos with the rotavap filmed and they'll probably pop up in January. There isn't lots of information out there on its culinary uses compared to most other equipment, but the 'Cooking Issues' website has some sections on it I think, if it's still online. Also Buchi themselves have a download of cocktail recipes that use it. I cant think of much more off the top of my head, but I will keep coming back to it because there's a lot of interesting things you can do with one
@@EddieShepherd Thank you so much :) Great videos
Hi Eddy, how much all your set up rotavap Buchi R-100 cost for ?
I hope this guy shows us a time lapse of like a glass of wine to shot of brandy or something.
Hi Eddie, do you see any volatiles in the cold trap? I am getting ready to perform a full co2 extraction of coffee which will yield in about 50ml of coffee oils + waxes. I then need to remove waxes without using alcohol or any other solvent so I was thinking about a small short path distillation kit. What would be your approach to this? I am cautious that I may loose volatiles into my vacuum pump…
You do get some volatiles coming though to the condenser & reviving flask, with this rhubarb reduction example the evaporated water bi-product has aromas of rhubarb.
I have a video on how I use the rotavap for making distillations I blend gin from, that might be useful to look at. Of course I am using alcohol there. I’m working on another video on more rotavap techniques at the mo.
Hey Eddie, do you use a recirculating chiller with your rotovap? I can see a vacuum pump in the video but no chiller...
Hi, Yes I do use the recirculating chiller. I'm wolfing on a longer and more detailed video about the Rotavap set up I have and more of the techniques I use it for, probably out in January I think
What flavour does the evaporated water have and do any of the rhubarb notes pass over with it?
Yeah so the evaporated water has a nice distinct fresh rhubarb aroma but no real sweetness or acidity. I do a similar reduction with blood orange and that gives you an aromatic blood orange evaporated water as a by product too.
I have used them in marinades, and they could have a ton of other interesting applications.
Could you combine the rhubarb/beetroot juice mixture with a neutral grain spirit, and put that in the rotovap to get a rhubarb/beetroot spirit/distillate?
