From the roaster
Guess what? I changed the name. It's like dungbum or bumdung and I'm sorry I just can't sell a coffee with that name. So it's humbug. Are you mad? Well I've been mad for like 25 years and I'm kind of tired of being mad. So one day I just said lol nothing matters spinning gif to the world and said listen I can play clash of clans and maybe warcraft rumble and watch some japanese baseball games and THATS IT.
This coffee does the thing you'll like. So much so I've almost gotten to the point of not wanting to write these because I've peered into the darkness and it punched me in the face with stinky cheese smells. I love these coffess and the Java rarity just ticked the boxes for me. There's some great chocolates going on really rich but I also found there to be a very "beer" like taste. Maybe a meade. I'm sober as fuck and I've not had a drink since longer than you've been alive KIDDO. Yes, YOU dear reader - I called you KIDDO.
Don't fear, I shoot straight with these coffees and if you like anaerobic naturals you'll like this.

Context
The Java Humbug Anaerobic Natural, offered by Royal Mile Coffee, represents a distinct expression of the Indonesia · Java terroir. By utilizing an anaerobic natural processing method, the producers have moved beyond traditional regional profiles to create a cup defined by unconventional, fermentation-driven characteristics. While standard natural-processed coffees often lean toward heavy fruit or berry sweetness, this specific lot highlights a complex interplay of chocolates, beer, and meade.
These unique sensory markers invite a deeper exploration of the flavor wheel, as the anaerobic environment alters the development of sugars and acids during the drying phase. This coffee serves as a compelling example of how modern processing techniques can reshape the identity of a classic origin, offering a profile that challenges the palate and rewards those seeking depth and nuance in their morning brew.
