Will a 2 liter soda bottle contain the pressure of beer or a sparkling wine?

I'm sure there are many reasons not to use the 2 liter bottle for this
purpose, and many better alternatives.  I'll thank everyone in advance
for telling me those facts, but, will a 2 liter plastic soda bottle
hold the beer or wine without exploding?  Say if the fermentation was
not complete or if it restarted?

I've seen 2 liter bottles pressurized to failure (not pressure gauge
used) and they seem pretty strong.  However I have no idea of the
strength needed, nor any idea of what a fermenting beverage could
generate.

Thanks

Yes, I've used them for cider.  I believe they're rated to around 100
psi. Or in other words, much higher than you need to worry about in
home brewing.

I've used plastic when in a pinch.  Actually better for soda or extra
carbonated things because it won't explode as easy as glass.  Permeable
to
oxygen though so don't use for long term storage...

Eric,
I imagine you are referring to the PET soda bottles we see just about
everywhere these days.
They are very strong & highly pressure resistant, over pressure is likely to
be detected by an extremely tight feel of the bottle sides & some
distortion.
Gently releaseing the cap will give you excellent feedback.
In my experience some leakage of gas from the screwcap seal can be expected
before the bottles finally fail.
I can't recall ever having a pressure failure of one of these bottles
regardless of size & yes I have used the two litre type.

I once bottled ginger beer in 2-litre PET bottles. After a few days, it was
pressurised to the extent that the caps started to dome up. Scary stuff. I
don't expect that malt beer would generate anything like that amount of
pressure - not with a mere teaspoon-full of priming sugar, anyway.

You should not have a problem with "pressure".  Your problem will
be possible "oxidation".  

PET bottles are made to contain pressure.  However, the oxidation
barrier of PET bottles will break down over time.  My policy is
to use them for short-term storage of beer (I don't make wine.)
Regardless of the number of times I use a PET bottle, I put them
in the recycle bag three months after their first use.

I hate bottling for two reasons: 1) it's skut work and 2) friends
seem to take forever to return the bottles.  For the second, I use
PET bottles for beer being given away.

If using the 2 litre bottles then after opening, draw off to a jug and
pour out drinks from there, otherwise if just taking off a pint from
the bottle, when you go back to it, it'll be cloudy as somehow it
draws the yeast off the bottom.

You could also try 1 litre bottles and then have the right amount for
a couple of pints.

http://www.prairiemoon.biz/sosisebofa.html  plastic soda bottles have a design rating of 200 psi.

1 atmosphere is 14.7 psi

http://hypertextbook.com/facts/2000/SeemaMeraj.shtml soda is around 55 psi (55/14.7 = 3.74 atmospheres)


http://www.angelfire.com/ks2/beer/homekeg.html http://www.kegs.com/faqs2.html beer is around 1 atmosphere (14.7psi)

If you make beer in plastic soda bottles you would be putting 14.7 psi in a
bottle designed for 200 psi. Obviously, soda bottles are over engineered
(200 psi rating to hold 55psi soda) so they don't break if banged around.
