Allen wrote, "Now, it's no secret that I am not a Liquid Smoke advocate." From the other side of the pond I didn't know that Allen. I tend to agree with you that maybe the smoker will remain the only tool to use when working bees, but nevertheless will test Liquid Smoke myself. It would be interesting to know whether others that have used this substance feel the same as you. If it is no good it will finish up in Thornes Winter Sale, alongside the Nasenhiemer formic acid evaporator, and many other useless pieces of beekeeping equipment - but you will never see an Open Mesh Floor in that sale.
