There is a wide diversity of Archaea species but a general culture media to fulfill the growth needs of most of them is that one proposed by Zeikus: add 0.5-1% sodium format or methanol or a gas mixture of 80% H2 - 20% CO2 to a basal medium that is described in Table 4, pag. 521. For anoxic species, resazurin should be added as an indicator of aerobic/anoxic environment. I used this culture media in my experiments and I could do methanogens Archaea cuantification by MPN technique.
