H&T - Do you even coffee?

[Presented internally in Novoda]

We have coffee and coffee machines. Hell, we even have really good coffee around the office, but how to use these facilities to make the most out of them? How to avoid having the coffee maniacs stare at you with dismay while you're brewing your cup?

Join Seb and Jon in this atypical H&T that will teach you DOs and DONTs of coffeemaking and should also help put an end to the whole "eww who left the coffee machine like that" business.

2. (Light vs Dark side) ROASTS
3. “development” timing, temperature (first & second crack) Maillard reaction caramelisation
4. The roaster has a goal
5. Filter Roasts • Lighter (shorter roasting time) • Preserve acidity • Bring out more complex but delicate flavours • Say no to milk!
6. Filter Roasts When used for espresso? • Kills more complex and delicate flavours • Overly acidic + astringent • Espresso roast more smooth, sweet, mellow
7. Espresso Roasts • Darker (longer roasting time) • Less acidity (since espresso brew exaggerates that) • Bolder, smoother flavour (withstands milk better) • Bring out and find subtleties in the body • More crema due to surface oils
8. Espresso Roasts When used for filter? • Quite a dull coffee, lacking complexity • Trying to compensate by brewing longer 
 just makes bitter black junk
9. Brewing basics Under Over “Sour” Watery Uninteresting Bitter Astringent Extraction Perfect

11. Espresso brewing • Grind & Pressure • Too fine 㱺 high pressure & surface area • 㱺 over-extraction • Too coarse 㱺 low pressure & surface area • 㱺 under-extraction • Temperature… less of an issue with this machine • Frothy milk? Ask Seb, not me :)
