While I’m generally skeptical of boycotts, BDS scares the shit out of Israel. Because I do believe if BDS becomes a global movement it really could change things. I’ll start with the list from bdsmovement.net and then add to the list as people list other companies to boycott in the comments:
Hewlett-Packard (computer hardware)
Siemens (tech conglomerate)
AXA (banking & insurance)
Puma (clothing)
Israeli fruits and vegetables (usually labeled)
SodaStream (idk that garbage home soda)
Ahava (cosmetics)
Sabra (hummus)
I'm suuuuuuper late to the party (is necrobumping a thing here? If so sorry!) but one tip for this setup is to not fill the bottles all the way. If you have a bit more headspace in the bottle, it's more effective to shake it and more CO2 dissolves in my experience.
Beyond that, having a high enough pressure for the part going into the bottle is important. I normally use 45 psi or so and that gets me the right kind of prickly water for my tastebuds.
I know you said you don't have it anymore, but just in case you wanna try again at any point in the future or just for people reading this, figured this might be useful.
I dont think necroposting is really a thing people care about here, no
idk what the issue was with my setup. water not cold enough perhaps, but it didnt seem to matter much when I did try it fully chilled... the keg had a fill line that I roughly observed. always was too much work for a substandard result.
