Siphon brewers are my favorite brewing method by far. After trying a few different filter methods for it I found that using glass filter rods make the best cup. The cloth filters in my opinion add a fabric flavor taint that really ruins certain coffees. I have seen metal filters before but I have never found a place to purchase them. The glass filter rods are amazing. They do not add any flavor taints, there are no cloths to clean, and they are reusable and recyclable. Bodum makes glass filters but they are around $35. You can easily find old vintage filter rods made by Cory on ebay for $5 to $10. It really makes a huge difference. Brewing parameters were accurately described above but it is one of those methods that you have to experiment with to hit the sweet spot as far as variables like brew time and volume.
Also since Summer is coming up and I am sure Charlotte gets insanely hot you should also research Toddy. Toddy is amazing. For a standard five cup toddy maker you need 1 pound of coffee ground to a little coarser than standard drip but it yields quite a bit because the final product is a concentrate that can be diluted. If you google "toddy coffee" they have directions on their website.
