Thanks in large part to an 18-day beer festival held in Germany, the month of October will forever be linked to the drinking of beer. Last week we tipped you in the direction of the six apps you need to get the most of your own Oktoberfest celebrations. This week we're taking it a couple steps further by showing you what you need to brew your own beer. Gasp! Chill. It's not as hard as it may seem. It's actually quite simple if you use one of these home brewing kits. Ranging from thousand-dollar industrial-grade machines to simple, plastic set ups, we've gathered the 5 best in-home beer brewing systems for those looking for something a little more exclusive than what's for sale at the local bodega.
