A lesson in Agriscience and Horticulture Using Southern Sweet Tea
Georgia Agriculture Education Curriculum Office
Catrina Kennedy and Dr. Frank Flanders
Solution-process of forming a mixture
Saturated Solution-when something can no longer be dissolved
Suspension-mixture which is finely divided that it does not easily settle out
Oxidation-gain of oxygen
Tannins-naturally in tea leaves, over boiling causes a bitter taste
Steep-soaking in water to release flavor
Adhesion-when things bond together
Surface Tension-property of liquids from molecular cohesive forces
Black Tea- normally what we drink, it has been oxidized longer, tends to have more caffeine and a stronger flavor
Green Tea- least amount of oxidation, can be found in the local grocery store
Oolong Tea- the in-between tea, it is brewed strong and bitter but leaves a sweet aftertaste
*This is generally the process that black tea goes through
Tannins are a chemical found in many plants. They are important to the production of some items such as wine. However, tannins are not necessarily a good thing when it comes to tea. If you boil your tea for too long it will have a bitter taste. This is because of the natural tannins in tea. In making tea, it should be brought to a boil and immediately removed from the heat.
Have you ever wondered why water is clear in some areas but dark in others? The reason is because of Tannins. Rivers in North Georgia are fast moving so the organic matter doesn’t have time to decay. In South Georgia the water is slower moving so plant material has more time to decay.
Camellia sinensis is what is used to make tea
Camellia japonica is what is generally used in landscaping. The only difference between the two is the species.
Step 1 Gather materials and equipment
Step 2 Cooking the tea (based on 1 gal)
*Place 2 family sized tea bags in a pot of cold water
Step 3 Bring to a boil and then remove from heat. Allow it to steep for approximately 1 minute. Remove tea bags.
Step 4 Add 2 cups of sugar to a pitcher.
Step 5 Add the HOT tea to the sugar and allow the sugar to dissolve.
Step 6 Fill the remainder of the pitcher with water and stir.
Step 7 Put ice into a glass and add tea
Step 8 Enjoy!
* This recipe should yield enough tea for 2 southerners or 137 northerners!
Tea Bags $.33
Bag of Sugar $.72
Total $1.05 per gal
