By resuspending them through b\u00e2tonnage, you can get the most out of the wine style you want to produce. In addition, this process requires careful management\u2014as we\u2019ll explain below. <\/p>\n\n<h2 class=\"wp-block-heading\">What are lees?<\/h2>\n\n<p class=\"wp-block-paragraph\">Lees can be described as the \u201cmother\u201d of wine. They have a pale yellow color and a bread-like aroma. During their breakdown (autolysis), mannoproteins are released. Lees also contain polyphenols, which contribute color and structure. To prevent fine lees from precipitating, the b\u00e2tonnage technique is used. Do you remember how it works? Don\u2019t worry\u2014<a href=\"https:\/\/www.lev2050.com\/en\/bioreactors-that-perform-lees-stirring-batonnage-2\/\" target=\"_blank\" rel=\"noreferrer noopener\" title=\"https:\/\/www.lev2050.com\/reactores-batonean-lias-battonage\/\">we recap it in this post<\/a>.      <\/p>\n\n<p class=\"wp-block-paragraph\">Lees act as natural protection against oxidation, helping reduce the need for sulfur dioxide (sulfites). They also preserve aromatic persistence while adding volume and structure to the wine.<\/p>\n\n<div class=\"wp-block-image\"><figure class=\"aligncenter size-large is-resized\"><img fetchpriority=\"high\" decoding=\"async\" src=\"https:\/\/www.lev2050.com\/wp-content\/uploads\/2025\/05\/pexels-posawee-suwannaphati-391213-1-1-scaled.jpg\" alt=\"\" class=\"wp-image-1556\" width=\"342\" height=\"389\" title=\"\"><\/figure><\/div>\n\n<h2 class=\"wp-block-heading\">How are lees generated?<\/h2>\n\n<p class=\"wp-block-paragraph\">Just like with yeasts, lees can be produced using BR-LEV-LC and BR-CV bioreactors through their b\u00e2tonnage program\u2014delivering significant cost savings in wine production and tighter control of winery operations, <a href=\"https:\/\/www.lev2050.com\/multiplicadores-de-bacterias\/\" target=\"_blank\" rel=\"noreferrer noopener\" title=\"https:\/\/www.lev2050.com\/multiplicadores-de-bacterias\/\">as explained in this other post<\/a>. <\/p>\n\n<h2 class=\"wp-block-heading\">What do lees contribute?<\/h2>\n\n<p class=\"wp-block-paragraph\">Lees contribute highly interesting aroma notes (bakery, pastry, dairy), along with proteins, fatty acids, and polysaccharides that increase mouthfeel creaminess, volume, and structure.<\/p>\n\n<p class=\"wp-block-paragraph\">In short, b\u00e2tonnage leads to wines with greater quality and complexity.<\/p>\n\n<h2 class=\"wp-block-heading\">Recommended products<\/h2>\n\n<p class=\"wp-block-paragraph\">LEV2050 recommends using FLO-1, a flocculant liquid yeast designed for propagation and subsequent b\u00e2tonnage in LEV2050 bioreactors. This enables the production of a lysate with balanced protein and polysaccharide contributions for wine finishing. It also offers the following benefits:  <\/p>\n\n<p class=\"wp-block-paragraph\">\u2022 Very high economic profitability when produced in a bioreactor.<\/p>\n\n<p class=\"wp-block-paragraph\">\u2022 Increased volume and structure thanks to its polysaccharide and glycoprotein properties.<\/p>\n\n<p class=\"wp-block-paragraph\">In addition, we offer a yeast lysis medium, LIA-LEV, specifically designed to produce yeast lysates from any yeast grown in the bioreactor\u2014whether native or commercial. With this product, we can deliver different protein, polysaccharide, and aromatic profiles to our wines. <\/p>\n\n<div style=\"height:17px\" aria-hidden=\"true\" class=\"wp-block-spacer\"><\/div>\n","protected":false},"excerpt":{"rendered":"<p>In the winemaking process, it is important to carefully manage the lees that form in the tank during fermentation, resuspending them through b\u00e2tonnage to maximize the potential of the desired wine.
