in the cellar : Only the free run juice is used for this MCC product - ± the first 500 litres per ton. Krone Borealis is bottle fermented and then matures on the lees in underground cellars after which, prior to dégorging, the bottles are packed in wooden pupitres (turning racks) and the rémuage (turning of the bottles) is done entirely by hand. Krone Borealis is microbiologically stable, the true celebration of the vintner's art. It has recently 'grown up & come out' in sophisticated, elegant new packaging.
