Instead of having to buy from a convenient store, you can make your own beer from several choices of brew kits. It is very easy and convenient even for first timers. All you would need is the kit, sugars - to feed the yeast needed in beer making as these live organisms cause the fermentation and create the beer, and water.
When still not so sold out to home brewing, you could just use the pre-measured stuff found in brew kits instead of using the raw ingredients. But you would end up getting the same taste again and again if you limit yourself to these.
The first step in home beer brewing is the sterilization of your materials. This is important because other organisms that would thrive during the fermentation process aside from the yeast would cause the drink to taste foul. The concentrate that comes with the kit is then put into the vat together with lukewarm water. You then have to get the right temperature for the yeast to be added. If the temperature is too cool, the yeast would remain dormant and if it is too hot, it would die so it should be just right. The yeast is then stirred in and the mixture is bottled - airlocked - and is left to ferment for a week or so. After fermenting, your home made beer is ready for bottling. You will know that you are ready to do so when the bubbles in your mixture have stopped. This indicates that the fermentation process is already done.
Once bottled - bottles and caps usually come with brew kits - you can leave your drink to subside for some time or you can consume it right away. If you plan to shelve it for a long time, make sure that your mixture does not referment. In big breweries, they do this - prolong the lifespan of their beer - by pasteurizing the mixture or by filtering out the yeast.
Interestingly, some beer enthusiasts even suggest that brewing beer is good to motivate students. If the hobby gets them interested enough, slacking students might begin to formulate ambitions - of forming their own breweries perhaps, or even just spending hours of working hard to get a taste of fine brew instead of just bumming around. Aspiring beer connoisseurs like acting the part by tasting the best brews they could afford and then replicating these at home.
However, replication of gourmet beer is not possible for starter brewing kits. The equipment included in these packages are normally inflexible, designed only for the mixture that came along with them. Their sizes may be too small to experiment on ingredient proportions. However, the good thing is there are other brew kits that are more flexible. Also, you can assemble your own. Home brew shops certainly have what you want. Moreover, you can find alternatives in your market that may be cheaper than those sold at specialty shops. You don't have to be confined to the packaged brew kits in the market.
