Research laboratory



In order to carry out all the tests and analyses required for quality control, Guillaume Nurseries has set up its own functional laboratory and also works in close collaboration with certified and independent laboratories for some specific tests (indexing, PCR).

Every year we check our selections' aptitudes through the micro-vinification of each clone in order to improve our genetic selection work.

If you wish, we can put you in touch with our partner laboratories so you can carry out the tests and analyses you need, in a totally independent way .
