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. What you can do is to dilute the tap water available by using distilled water if you think that the concentration of some ions is high. Or you can also make use of some additives if you found out that the count or the concentration of some ions in the local water is too low. Eventually, the Prohibition was enacted, causing all types of alcohol to get banned. Since then, home brewing was the only way for people to get their beer, and a risky endeavor at that. The Prohibition got lifted in 1933, but at this time, only wine was allowed. It was only when President Carter passed the 1979 Cranston Act that home brewing beer got legalized again, partly due to the proliferation of crime involving beer smuggling cartels in the previous years. This is a must for brewers who use grains in their solutions. Apart from this, a straining vessel called the lauter tun should also be available to strain out large particles from the boiled beer. Siphoning Tools Siphoning is a good alternative to straining as it limits the exposure to particles in the air while it's being transferred from one fermenter to another or to individual containers. Though all of the cappers that are available in the market may work, there are some pieces of cappers that will do more than the rest. Try to invest on the more premium ones in order to save yourself from the inconveniences of bottling. Is it advisable to use absorbing bottle caps? If you are going to store the bottles of beers for an extended period of time then that is the appropriate motivation for buying the absorbing bottle caps. Again, mix well and allow the fermentation to happen in the recommended temperature. Monitoring the fermenting process. This is the process of turning the malt into beer. The initial stage of fermenting the beer can go on for days and the key here at this step is the proper monitoring of the temperature. When you use a higher temperature during this stage of home brewing, there will be a reduced effect of the beta amylase and as such there will be larger amounts of sugar in your beers. And finally; When you want to have a full bodied home brew, the recommendation by many is to use the low attenuation yeast strain.
