Unlike powdered nylon (polyclar), liquid starter mix, eliminating the silica gel settles out quickly and firmly in considerable effort of making up a sterile the bottled beer, and eliminates virtually starter. To start our new yeast, just break all chill haze. Silica gel is the best chill haze absorbant for home brewers, as it is the inner seal, and wait until the package swells before pitching. composed of just silica and water, and because it is composed of just silica and Reusing yeast is simple and does not require laboratory skills. At the end of a water. and because it is selective: it does brew, after priming, just scoop up half a not remove larger malt proteins re- cupful or so of yeast sediment from the sponsible for head retention, only those of floor of the fermenter (in a sterilized cup). the size that bond with tannins to create cover the cup tightly with aluminum or haze. Silica gel does this by virtue of its plastic wrap and refrigerate. The yeast structure; each powder-size particle is a will last 9 days in the refrigerator in microcellular 'honeycomb' sponge filled slurry form, ready to pitch the next brew with sterile water, with pores just large enough to let the chill haze causing without a starter.

Of course, yeast The powdered gel absorbs the haze should only be saved from clean-tasting proteins before settling out with the yeast in the bottled beer. The only thing silica brews.

So the beer tastes clean, what about its clarity? All beer will throw a chill haze when refrigerated if not lagered (aged under refrigeration) for 4 weeks to allow the haze particles to naturally coagulate and settle. Chill haze forms when malt polyphenols in beer (tannins) bond with malt proteins of a certain size when the temperature drops.
