+This study seeks to find the best flavor black tea at the best value price point for bulk drinking at work in the library.
+
+## Methodology
+
+Two library employees with extensive experience in tea drinking (i.e. drink at least one pot of tea per day) took part in a tasting session featuring seven widely available varieties of black tea.
+Each tea was prepared according to the manufacturer instructions printed on the box.
+A standard measure of milk was added to each prepared tea after the brew time was complete.
+
+Each tester sampled the tea taking several moments to savor the flavors. 
+Testers general impressions were discussed and recorded, as well as an overall rating out of five possible points.
+The highest rating awarded by individual testers was four (Red Rose and Taylors Yorkshire), and the lowest was one (Tazo Awake).
+
+Prices of tea brands vary significantly at each grocery chain.
+To find a standardized price for comparisons, we chose to use the price at Walmart which carried all brands tested.
+
+## Best Value
+
+In attempt to evaluate the best overall value, we used the equation:
+
+`Mean Rating / Price per Tea Bag`
+
+### Base Value Ratings
+
+{% assign teaValue = site.data.tea-data | sort: "value" | reverse %}
+| Tea | Value Rating |
+| --- | --- |
+{% for t in teaValue %}| {{ t.tea_brand }} | {{ t.value }} |
+{% endfor %}
+
+This surfaced two surprising results:
+
+- Best value was the rather unassuming *Red Rose Tea*, which tastes pretty good yet is available very cheap.
+- Worst value was the popular *Tazo Awake*, very often served at conferences and hotels, which tastes terrible yet is very expensive.
+
+<!-- (tast weight * rating)/(price weight * price)-->
