This is the 800ml server from Hario. I make 600g water / 30-35g coffee in it every morning.
I drink my coffee slowly, and really like it hot. When I made a single 300g cup of coffee, I’d time my consumption wrong and it would be lukewarm before I finished. I didnt necessarily mind this, but now that I’ve been using this server I get hot coffee on demand, very conveniently.
I downsized my regular mug for a teacup, so I always get just enough hot coffee to sip and enjoy before it loses too much temp. So now I drink a lot of small teacups worth instead of a regular mug. I recommend you try this style of serving coffee and see if its for you.
Bonus: this has been so helpful when making for multiple people, since I dont always know when others wake up or come downstairs. Since its a huge insulated server I never worry about not being able to serve my roommates hot coffee.
I agree with the other commenter, your question is more likely to be seen by enough people for you to get helpful answers if you post it separately (especially since lemmy is small and the coffee community is a very small subset of that) but thats a great question and I’d be curious to see folks’ recommendations if you do end up making a post about it :)
I’m not very coffee knowledgeable myself so I don’t know that I could give a helpful answer, but I wish you well with figuring it out!
