I've been lurking around this forum for about 3 months now, never signed up and posted something until today.
to pitch my 2 cents (or a dime) on the Soda Talk, some things i've learned:
If you can afford to force carb, do so. yeast is problematic when you aren't using it to make alcohol.
If you cannot afford a Tank and regulator, make your own... well, kinda: CO2 Generator
It's at least worth the experiment.
Have other hobbies: Wine making can turn the above into a 2 for one process (just make sugar wine, use the escaping CO2 to carb up your sodas, then add flavor to your wine base.) learn about making extracts and use your own for sodas, look into soap making, Beer Soap could work... maybe...We're looking into it.
Look for flavors everywhere, I also want to know if an avacado soda would work... quickly to be followed by Tomato Soda, jalapino Soda and Tortilla soda..
Tell everyone your horror stories and pass on what you learn from them (don't use coconut milk in a soda) there, now YOU wont be tempted.
Soda is more incentive to making a Beer-Gun than beer is..
When you get around to buying a CO2 canister and regulator, remember this: you can keg without kegs: Cheap 3 Liter Kegs
combine that with your beer gun and start a business.
