Double lever hand corkers, often called a twin lever
corker come with either with a spring to hold bottle or a clamp, both have a nut at the top to
adjust the ram length.
Gilda single lever, crimping jaws similar to floor corker, is all
plastic. It struggles with composite corks and any of the thermoplastic corks. It was great with
the (real)first corks, but has fallen out of favor.
Floor corkers are the cat's meow. The Italian floor corker
is33" high, with a chrome or brass iris. It fits the Bellissima
bottles. The Portuguese floor is 27" with a Teflon iris. Does not fit Bellissima
Tom uses the Portuguese as he is tall and strong and can sit down and still ram the cork home with the shorter
unit. They both have replacement jaws.
