Using a Pocket Scale: Low-Tech Precision for Kombucha Brewers

We receive a lot of questions on the use of loose-leaf teas in kombucha brewing. This is a good thing - loose-leaf teas provide the most flavor and the most bang for your buck, as compared to commercial teas packaged in bags.   That's not to say tea bags aren't practical - they make it very easy to steep your tea, and what's in the bag is usually the remains of the processing of loose-leaf tea - this can include dust and fannings, or broken pieces of leaf - and is intended to be able to be steeped relatively quickly.   Loose-leaf tea, however, requires more effort than simple dunking to elicit the flavors and nuances of the tea. And, you're actually steeping the whole leaf - ideally, no broken pieces are part of the infusion.   Since the whole leaf is used, it poses an issue for many people used to volumetric measurements common in baking. Twelve grams of one tea will comprise a different volume than another tea. See below an example of 12 grams of 3 different types of tea:

Consistency is important

  For any brewer who wants to consistently reproduce brews and generally improve technique and the quality of your brew, it helps to be accurate with your measurements. This couldn't be more important than with the steeped ingredients for your kombucha brew; you could be steeping all one tea, or using a multitude of different teas and herbs in a blend. We can easily make suggestions and approximations of the volume of teas, using tablespoons etc., but the most accurate way to measure tea is by weight. This can be simple, but expensive with a digital scale; it can be inexpensive and simple, too.  

Using a pocket scale

For starters, you'll need something in which to weigh your tea. One of the easiest things to use is a nylon mesh bag that you may be steeping your loose-leaf tea in, or any zip or sandwich bag you have handy. You'll need to put your tea into the bag, and add or subtract some based on the weight you're looking for.

In this example, our nylon mesh bag weighs 4 grams:  

So, we can "tare" the scale at 4 grams - meaning that after we weigh the tea in the bag, we'll subtract the 4 grams that represents the weight of the bag.  

Once you know how much your bag weights, you can then begin to add your tea:

 

Once you've added the correct amount of tea for one gallon, you should see this - a 16 gram reading on the scale:

 Simple, effective, economical

A pocket scale is an excellent, inexpensive way to make your recipes accurate, and therefore consistent and easily replicable. This is one of those must-have items for any kombucha brewer (in addition to the regal auto-siphon). Pick one up and you'll be on the way to 'buch brewing perfection in no time!
