Kitchen actions of weight and also volume (in the foreground). May not be as accurate as you’d like. Relatively inexpensive scientific equipment can improve your ability measure things accurately. However, even without them, there are means to reasonably accurately sweet out tiny amounts.

You are watching: How to measure small amounts of liquid


Many homebrew recipes space scaled under from commercial-sized batches. And occasionally you’ll find that the amount of specific ingredients or additives compelled at the homebrew scale is small, or even tiny. To make matters worst, the capacity for homebrewers to accurately measure small weights and also volumes is typically limited. Even scaling a regular, 5.0-gallon (19-L) homebrew recipe down to a 1.0-gallon (3.8-L) test batch occasionally results in details additions that hops, various other spices or mineral salts to be smaller sized than deserve to be easily measured.

Most cooking-type scales only measure under to 1/4 oz when collection to English units and also 5 g when set to metric. (And note that these are close, however not the same. A quarter ounce is 7.1 g.) more accurate scales or balances room available, but they are usually pricey. Along those very same lines, measuring little volumes that liquids (for instance hop extracts) have the right to be problematic because that homebrewers who may have actually only kitchen measuring cups — or teaspoons and tablespoons — available.

Measuring dissolve Substances

In the situation of solids or liquids that are soluble in water, over there is a straightforward workaround. If you need to measure out the load of a solid or the volume that a liquid the is listed below the resolution that your scale or measure cup, making a well-known solution will help. Basically, girlfriend dissolve a known amount that the problem (more than you need) right into a recognized volume of liquid. Then, girlfriend dispense a section of the volume, which has the correct amount of the dissolved substance.

Let’s to speak you’re unavoidable a little batch that beer and it calls because that 3.5 g the calcium chloride come be included to your impending liquor. But, the smallest increment her scale procedures is 5 g. The an initial step would certainly be come measure out the the smallest amount of calcium chloride the you space confident her scale have the right to weigh accurately. If the smallest increment is 5 g, you can go v 5 g. Or, you can pick a larger amount. (Calcium chloride is cheap.) for the benefits of example, let’s say girlfriend weighed out 10 g.

Your following step is to dissolve the solid in a volume of water. You require the equipment to be dilute enough to totally dissolve the solid, but you don’t desire to mix increase a needlessly vast volume, either. In this case, lets say you dissolved 10 g right into 100 mL that water, yielding a systems of calcium chloride with 1 g per every 10 mL. Including 35 mL the this equipment to your impending water would include the 3.5 ml the calcium chloride called for.

This method is just as accurate as her scale and also measures of volume are. Be conscious that kitchen scales and measuring cups space not scientific tools. They should be close enough for any situation in homebrewing, however if you want to be much more accurate, obtain a triple beam balance and also a collection of graduated cylinders (10 mL and also 100 mL, and also maybe one bigger size, the needed). A continuous classroom-type triple beam balance will let you sweet items to 0.5 g and a decent 10 mL graduated cylinder will certainly let you measure as tiny as one 0.1 mL (+/- around 2%). This will be overkill in virtually any homebrewing circumstance.

The an approach above just works for things that are completely soluble in water. And for points that space expensive or perishable, make a dilute solution might be costly or wasteful. Still, it will occupational for any mineral salt or sugar, and also could occupational for part spices. (And you likewise have the choice of do an alcohol extract of flavors with vodka.)

Insoluble Solids — A Quick and Dirty Method

For solids that aren’t completely soluble in water, like hop pellets, yes sir a “quick and dirty” way to measure up out little amounts. The is accurate enough for most homebrew situations, particularly if you understand you have a tiny leeway in her measurements.

Let’s say her recipe calls for 3/5 oz. (or 0.6 oz.) of hop pellets and you don’t have actually a range handy. However you do have a 1.0 oz. Packet the hops the you to think to be sensibly close to the exactly weight. Pour the pellets top top a level surface and push them all together in a small hill. Now, together accurately as you have the right to eyeball it, divide the hill into two same parts. Currently you have two piles, every at 0.5 oz. If 0.5 oz is close enough to 0.6 oz. For your liking, climate you room done.

If not, take one of the piles and also divide the in fifty percent again. Currently you have actually one heap at 0.5 oz. And also two piles at 0.25 oz. Dividing one the the smallest piles equals yields piles that 0.5 oz., 0.25 oz., 0.125 oz. And also 0.125 oz. Combine the 0.5 oz pile with one of the 0.125 piles is 0.625 oz. If it is close enough, your done. If not, keep separating one the smallest piles till the sum of one set of piles is close sufficient to her target for your taste.

For measure up out tiny amounts the mineral salts, you can use a dark plate and a razor blade or credit transaction card to separate the piles. Simply be certain that no one is likely to walk in top top you all of sudden — unless you room starring in your community theater’s production of Scarface.

The accuracy the this technique depends on her initial measurement and also how great you space dividing small piles exactly in half. In a pinch, this have to do fine in any type of homebrew situation. If it appears too error prone for you, invest in a triple beam balance — which should be more than sufficient in any kind of homebrew situation.
