Using helium to make home brewed beer

I want to brew beer using helium instead of $\ce{CO2}$.


Most beers use about 2.5 grams of $\ce{CO2}$ per litre except stout like Guinness which uses nitrogen as it allows bubbles for much longer hence a frothy head on the stout.


So, perhaps a blend of helium and nitrogen would work? Helium is more soluble and if used in place of $\ce{CO2}$, as soon as the seal broke on a can it would escape rendering the cartoon voice idea useless.


How much helium can I squeeze into a litre of beer with or without compounding it to get the chipmunk voice?




To correct one point in the question, helium has the *lowest* water solubility of all gases. At one atmosphere and $\mathrm{25^oC}$, $\ce{CO2}$ is 100 times more soluble than $\ce{He}$ and $\ce{N2}$ is about twice as soluble as $\ce{He}$. This is why deep-divers prefer helium to nitrogen.


At 45 psi, which is 3.1 atmospheres pressure, you could dissolve about 0.005 g $\ce{He}$ or roughly 30 mL when fully degassed. A typical adult breath is around 500 mL, and of course the $\ce{He}$ will not degas instantly. 


The bottom line is that pressurizing beer with helium will not make you talk like Donald Duck. And the biggest difference you would see between $\ce{N2}$ and $\ce{He}$ would be in your bank statement.
