when the batteries only give one boil, Folgers instant coffee

Three weeks of this on the boat, mostly one mug at 6am before the batteries have anything to give beyond a single boil. Folgers Classic Roast instant coffee, part number 025500206295, comes in an 8 oz jar measuring 3.59 by 3.59 by 6.63 inches, which sounds like trivia until you are fitting it into a locker that already holds the sugar and the spice tins. Against a pod machine and against a Nescafe Gold jar it undercuts both, and it lands a step above the value tins nobody names out loud. Small appliances and their manuals are my day job, so the label instructions got read, which is more than most people do with instant.

One rounded teaspon to six fluid ounces is what Folgers tells you and that is close to right, though I go slightly under because the classic roast leans bitter if you get heavy handed. The jar holds 236.59 ml by volume and 8 ounces by weight, which gave me somewhere near six weeks of one mug a day before the bottom came into view. Dissolving happens instantly in hot water with no clumps, while in cold water it needs a proper stir and never fully behaves. Aroma out of the jar beats aroma out of the cup by a mile, which is the usual instant coffee trade off rather than anything Folgers did wrong. It tastes like a diner cup, flat and familiar, no burnt edge, and it takes milk far better than it takes being drunk black. Against fresh ground it loses on every measure except effort and power draw, and on a boat those two measures win a lot of mornings, which is also why the Maxwell House jar next to it never gets touched. Storage has been fine, the lid seals properly and the powder has not caked once in three weeks of damp air, which is a lot more than I can say for the paper sachet stuff sold at twice the price. 4.7 from 30300 reviews with 20000 sold last month is a lot of agreement, and mine matches it, with the caveat that jars do turn up packed hard enough to need a spoon handle to break in. The J.M. Smucker Co. also wrapped mine in some limited edition anniversary packaging, which changes nothing inside the jar and confused me for a second on the shelf.

Question for the long term drinkers, does the classic roast instant coffee stay this consistent jar to jar across a year, or have you had a batch land noticably weaker than the last?
