As a homebrewer you're ultimately going to want brown beer bottles and caps or a kegging system to contain your finished product. There are many alternative options for the first time brewer. You can buy empty bottles and caps. You can reuse bottles and buy caps (not the twist-off cap bottles). If you're going to use regular pry-off cap bottles you're going to need a capper (included in starter kits) to press fit the caps on the bottles. You can reuse champagne bottles. You can reuse empty growlers from your local brew pub. You could use empty soda bottles and caps. In any case it's important to use something that will withstand pressure in the bottle resulting from carbonation. Again, sanitation is important. So, clean and sanitize the bottles prior to filling them. Soaking in a diluted bleach solution for 30 minutes and rinsing with clean tap water will do the trick.
