Their fruit purees are made with real fruit, not concentrates or juice. The resultant sterile puree can be added directly to the primary or secondary fermenter, without worries or contamination or the work of crushing. Great for Summer wheat beers and light ales. As most home brewers know, Sierra Nevada Brewing Company produces some of the best commercial beer available. They have combined their three mainstay beers with a line of mustards that are uncompromising in quality.
Yeast needs oxygen to reproduce and produce strong cell walls.
If the cell walls are weak, the yeast will have a low tolerance for alcohol, and can die before fully fermenting out the wort. Particularly in worts with starting gravities in excess of 1.050, this can contribute to long lag times, slow ferments, and higher than normal finishing gravities. Like an air stone in a fish tank provides oxygen for fish to breathe, wort aeration provides needed oxygen for yeast respiration and growth.
