The yeast starters 2x CL400 (at the back) and a small CL930.About BrewTek
A number of books, online recipes and brewing software (such as BeerSmith) reference BrewTek yeast, these yeast strains were used very successfully in many home-brewed beers. Until about early 2003 Brewers Resource supplied BrewTek yeast (numbered as CL-#) on slants via their website. As of about 2004, Brewsters Yeast offered BrewTek strains , however in 2007 Brewsters Yeast also closed their operation. Since that time the only way to obtain BrewTek yeast (except in large volume or commercial situations) is via home-brewers who have saved this these yeasts at home or in their on labs.
