Hi guys! Total newbie here, and since I got half of my brewing equipment from my dad, including old bottle capper, I was wondering if anyone knows is there any difference between mine INART bottle capper and new "designs" sold in markets today.
I have old INART bottle capper, and it has a wing screw on top of it. Does that adjust something, or is it just for keeping my capper in one piece?
Heres a pic of similar
Any thoughts should I use this or just buy a new one?
Cheers!
