Yes, those Trappiste beers are quite interesting, Chimay for example which is available in different signal strengths (QRP..QRO), but I don't believe it is possible to get them in metal cans. As a compromise, you can try to wrap the bottle in metal foil, or, avoid drinking it and solder the FET gate directly to the bottle's cap. :-)

Oh no.... avoiding drinking it would be asking too much.... :-)

And G4GVW says :

We may, therefore, suppose that S/N ratios might depend on the number of
samples, their frequency and relative signal strengths. The condition of
the observer should,probably, also be taken into account!

Correct... so to reduce the variance, what would be needed is a much greater 
number
of samples so to average out the statistical fluctuations... hmmm, not too bad 
a task...  :-)
