And since these ions are critical, it is always a good move to research on the composition of water. And this can be done by asking for a report from the local water utility. If one or more of these ions are present in high amount in the local water, then you can always 'adjust' the content of the local water for brewing. And if the person is not too concerned with cleanliness in workplace then this can make the brew unfriendly to the taste buds. So what needs to be done in order to address a concern like this? The best thing to do is to ensure the cleanliness of equipments every time. All the equipments used in home brewing should be sanitized. Beer and wine are quite arguably the most popular among home brewers but brewers who produce cider, silju (a Finish home-brewed alcoholic beverage), ginger beer, Kumis, Sake (Japanese rice wine), Chhang (a popular Tibetan alcoholic beverage), Kvass (a Polish bread drink), mead or honey wine, and kombucha are not uncommon favorites. The act of brewing your own beer also gives you that mad scientist fulfillment (or at least for me), not to mention the satisfaction that you feel every time your beer-guzzling friends rave about your concoction. Better Quality For Your Beer Home brewed beer, unlike commercial beers, doesn't have cheap additives. Home brewing hobby shops had steadily increased in number in the intervening years. In 1981, home brewing hobby shops have amounted to 150. They have grown to 1,000 in 1996. After some retrenchments, the number dwindled to 550, one of the reasons being the rising costs of materials. Commercial breweries have permeated the fabric of society since then, but while home brewing was still legal, it dropped down in popularity and was relegated to "connoisseurs" and fanatics. Let it boil for 5-10 minutes then take it off from the stove, dip the pot in a cooled water to cool the mixture faster. On this stage the mixture you just made is called wort (pronounced as wert) 4. While cooling the wort, sterilized (either, by pouring boiled water or using sanitizer) the fermentation pail, airlock, spoon and thermometer.
