I am looking to buy an instrument for pressing the juice out of grape samples of small size (up to 1 kg of grapes). As the pressure applies to the grape samples can affect the extraction of the compounds I want to measure, I am looking for tools with pressure control so to be able to standardize the pressing among samples. Any suggestion of suitable instruments? thanks!
Dear Metteo,
My advice is to use simple press for kitchen (there are different solutions). I don’t know are there on market something new that can help you. We use hand pressing for small grape samples (up to 200 g) what is also good enough. Grape press in real scale you can not simulate easy. The most important is that you can repeat the in what way you get juice. I am sure that any good, small press with manometer does not exist.
Dear Leo, thanks for your suggestion. I have used hand pressing in the past but I am looking to avoid variability in the samples' composition induced by this procedure. I have found one company in NZ that makes a type of bench press with a manometer for grape processing so the product does exists. However, I am interested in knowing if someone else have come across this issue and how it has been dealt with. Cheers
