Renewable winemaking —often called green or sustainable winemaking—is a holistic approach that focuses on minimizing the environmental footprint of production while regenerating the land. Here is the step-by-step journey from vine to glass, highlighting modern shifts. 1. Harvest & Sorting The Decision: Winemakers now use satellite imagery and AI sensors to measure grape ripeness (Brix, pH, and acidity) in real-time, picking the exact hour for harvest. The Action: Grapes are picked by hand (for premium styles) or by "optical sorters"—machines that use high-speed cameras to "flick" away any grape that isn't the perfect color or shape. 2. Crushing & De-stemming The grapes are separated from the bitter green stems. Red Wine: Grapes are lightly crushed but kept with their skins to extract color and tannins. White Wine: Grapes are immediately pressed to separate the juice from the skins to keep the wine crisp and clear. 3. Fermentation (The Ma...
What is Osmotic Power? Osmotic power (also called salinity gradient power or blue energy) is a renewable energy technology that generates electricity from the difference in salt concentration between two bodies of water – typically seawater (salty) and freshwater (river water). When these two waters meet, a natural osmotic process wants to equalize the salt concentrations, and we can harvest the energy released during that mixing. There are two main technologies: Pressure Retarded Osmosis (PRO) – the most developed and commercially tested method Reverse Electrodialysis (RED) – uses ion-exchange membranes to produce electricity directly Principle of Osmotic Power How Pressure Retarded Osmosis (PRO) Works Freshwater is pumped into a chamber separated from seawater by a semi-permeable membrane. The membrane lets water molecules pass but blocks salt ions. Because seawater has higher salinity, water naturally flows from the fresh side to the salty side (osmosis), increasing pressure...
