Hop Harvest Moisture Calculator To use this Hops Calculator, please enable JavaScript STEP 1: Weigh a Sample Weigh a sample (A) of your harvested hops, making sure to 'tare' the scale before adding the hops, or subtract the weight of the container from the total weight. Sample (A) Weight: grams STEP 2: Dry the Sample to 0% Moisture & Re-weigh Dry out the sample with a microwave, dehydrator, or oven. If using a microwave or oven, stir the sample every minute to prevent scorching! Weigh frequently: the sample is at 0% moisture when it no longer loses weight. Sample (A) Weight at 0% moisture: grams Harvest Moisture is % moisture (by weight) Harvest Dry Matter is % dry matter (by weight) STEP 3: Weigh Another Sample Weigh a second sample (B) from your harvested hops, making sure to 'tare' the scale before adding the hops, or subtract the weight of the container from the total weight. Sample (B) Weight: grams STEP 4: Weigh an Empty Sample Bag & Fill it with Sample (B) Select an empty sample bag that air can easily pass through (mesh or other permeable material) and weigh it. After you have recorded its weight, fill it with sample (B) and then place it in the oast with the rest of the harvest. Empty Bag Weight: grams STEP 5: Choose a Target Moisture Content Decide on your target final moisture content. In general, hops should be dried to 8-12% moisture, with 8-8.5% being optimum. Target Moisture Content: % moisture (by weight) Sample (B) will weigh grams when it reaches % moisture (by weight) Including the weight of the bag, your Target Weight is grams
