About MasonTops
Founded by childhood friends Phil Baron and Mike Bacher, Masontops started with a joint appreciation of Mason jars. Go to your cupboard: chances are you have at least 4 Mason jars tucked away. Although they've been around since 1858, Mason jars continue to be a versatile storage vessel, crafting tool, and decor item. Inspired by the utility of the Mason jar and allure of its vintage charm, Masontops strives to help people upcycle their jars. Masontops is dedicated to creating Mason jar accessories that turn Mason jars into beautiful storage solutions, easy fermentation vessels, coffee bean preservers, and more! Masontops products make food fermentation accessible to everyone, regardless of their experience level. Incorporating fermented foods into a balanced diet and active lifestyle can lead to a healthier and ultimately happier life. Fermented foods are loaded with good bacteria and probiotics that are proven to improve gut health, boost immunity and increase nutrients absorption.
