Buy a bigass fvcking jug of Mead.
Ideally, apis poltorak jadwiga. No, I don't know what the fvck that means, but that's what it's called.
Dansk Mjod Vikingernes Mjod is probably my 2nd favorite commercial mead that I've tried... easier to find vs the Jadwiga and usually less expensive too.
Otherwise, Viking Blod is good, though it's obvious it hasn't been aged nearly as long, and it's a bit rough, I like the flavor since it's got some hops and hibiscus for flavor.
Otherwise, Chaucers Mead is about the cheapest I'd go, it's a bit light with only around 10% abv, and it's not nearly dry enough, but it can be good from time to time.
