It's not possible to say exactly how much L-theanine is in Earl Grey tea because Earl Grey is hugely variable, as it is a style of tea that can be made from different base teas, and is characterized more by the bergamot flavoring added.
All tea contains a relatively high concentration of theanine, compared to other food and drink. The teas known to be highest in theanine, however, Gyokuro and Anji Bai Cha, are both green teas and are generally not used as the base for Earl Grey. Typical Earl Grey tea would thus be considerably lower in theanine than these teas, but probably average among other teas.
You can taste theanine; it has a savory or "umami" flavor, a lot like a soup or stew, or similar to the flavor added by MSG.
