This is a great choice for stuck beer fermentations and also for unique HG beers with unique foam characteristics and mouthfeel. At $0.95, it's a good backup. Here's the formal description: A sturdy yeast ideally suited for fermenting Champagne, the EC-1118 strain was isolated, studied and selected from French Champagne fermentations. Due to its competitive factor and ability to ferment equally well over a wide temperature range, the EC-1118 is one of the most widely used yeasts in the world. The fermentation characteristics of the EC-1118 - extremely low production of foam, volatile acid and H2S - make this strain an excellent choice. This strain ferments well over a very wide temperature range, from 7° to 35°C (45° to 95°F) and demonstrates high osmotic and alcohol tolerance. Good flocculation with compact lees and a relatively neutral flavor and aroma contribution are also properties of the EC-1118. This strain is recommended for all types of wines, including sparkling, and late harvest wines and cider. It may also be used to restart stuck fermentations. 7 gram pack for 5 gallons of wine or cider.
