Are the silicone seals safe for high proof ethanol, in the 65% range (~130-150 proof)?

I would say no, as most silicone is only conditionally resistant to alcohols. I believe temperature and concentration are the determining factors, with temperature being most important. If you're doing home distillates, any amount of fore shots leaking into the heads and hearts will eat at the seal very quickly.

Is the outside of the bottle smooth or indented?

It’s smooth and the bottles are really nice

Will these bottles work with soda stream carbonator without attachmet?

Hi please check the size, the 33fl oz might too tall to fit, its 12" bottle height without the cap. For the 16fl oz the height is 10 3/8". A customer mentioned that the Sodastream bubbles still go away. Please check your Sodastream height requirements. Thank you for your question!

Good bottles for fermented liquids!

Sturdy, well-made glass bottles. Good for water kifer and other brewed liquids. Excellent wire, plastic, and silicone top closure. The silicone washers are especially nice. High quality and seems like thick glass.
