Taylors Hot Lava Java Coffee Bags: The Dark Roast That Is Hard to Over-Brew, in summary: Hot Lava Java is the smoky, dark end of the Taylors range, here in ten sealed coffee bags. A bag brews more gently than a cafetiere, keeping the smoke and dark chocolate but little of the harsh edge.

A bold dark roast is the easiest coffee to spoil, and a coffee bag is one of the hardest ways to spoil it. That makes this carton the gentlest route into the loudest coffee Taylors put behind a filter.

Why a smoky roast suits a filter bag

Push a very dark roast too far and it tastes of ash. The usual culprits are a long steep in a cafetiere, pressing hard on the plunger, or letting the pot sit on its grounds while you drink. A coffee bag rules all of them out: water simply soaks through without being forced, so the brew stays mild in the right way. Smoke, dark chocolate and a burnt-sugar note come through, minus the rough, drying finish, in a mug slightly lighter than a jug would give.

Taylors, the Harrogate family firm better known for its tea, sorts its coffees by roast style rather than origin, and Hot Lava Java is the bold one, meant for drinkers who have worked through the breakfast roasts and found them too polite. Each carton holds ten individually sealed bags of 7.5g, 75g in total; for the blend details and any roast number, read the carton itself.

A full mug, not an ashy one

An ashy mug almost always points to water straight off a rolling boil. Give the kettle half a minute to settle, bringing it nearer 95 degrees, then steep for three to four minutes. This dark roast is happier at the longer end than lighter bags are and repays the extra minute with a heavier cup. Leave it past five, though, and the smoke turns to ash that milk cannot rescue.

The other trap is drinking with the bag still in the mug. It carries on extracting, and what comes out late is bitterness, so take it out once the time is up. If you take milk, add it after brewing, never before: for a milky mug, brew one bag in about 150ml of water for three minutes, lift it out, then pour in the milk.

Who it suits and what to eat with it

This carton is for anyone who wants a dark, smoky mug with nothing but a kettle to hand: no grinder, no plunger, no wet grounds to tip out. It is also a gentler way in for those who find the same roast punishing from a cafetiere. It is not for people who take coffee pale and sweet; the Rich Italian in the same range is the better start there.

Roast depth is not a caffeine measure: this tastes strong because of body, smoke and bitterness, not because there is more caffeine in the bag. Against that smoke, pick biscuits with sweetness and weight. Oaty Hobnobs and caramelised Biscoff give the roast something to lean on, and a dark chocolate ginger biscuit matches its intensity; delicate biscuits simply get lost.

FAQ

Does a bold roast like Hot Lava Java have more caffeine? No. How dark a coffee is roasted and how much caffeine it holds are separate questions; the strength you taste is body, smoke and bitterness.

Why does my Hot Lava Java taste ashy? Usually boiling water or a bag left in too long. Let the kettle rest half a minute and lift the bag out before five minutes.

How long should a Hot Lava Java coffee bag steep? Three to four minutes. Four gives a heavier mug; past five it slides towards bitterness.

Do I need any equipment? Only a mug and a kettle. There is no grinder, plunger or filter paper involved.

How much coffee is in each bag? 7.5g, with ten individually sealed bags making 75g in the carton.

Curator's note: Take the kettle off before it roars and pull the bag at four minutes. Made that way it is smoky and dark without being a punishment. Lee, teas.co.uk, Tunbridge Wells.
