Colonists asserted their independence at the Boston Tea Party by lulling British officers to sleep with cups of chamomile and drawing marker mustaches on their faces. Harness the revolutionary power of tea with today’s Groupon: for $20, you get a loose-leaf tea sampler plus 10% off tea accessories at Indigo Tea Lounge (a $42 value). The sampler includes a 2-ounce bag of each of the following teas:

• Lychee-red black tea
• Bossa Nova oolong tea
• China gunpowder green tea
• Coconut-crème white tea
• Peppermint herbal tea<p>

Substitutions are allowed, as long as tea is of equal or lesser value.

Amid shelves lined with more than 150 varieties of loose-leaf blends, Indigo Tea Lounge’s tea savvy staff helps customers find a sip suited to their palate. Indigo’s tea sampler energizes home-brewed cups with 2-ounce, individually sealed bags that encompass a sippable spectrum of flavors. The lychee-red black tea emanates smooth, fruity aromas, and the herbal peppermint tea enlists Washington peppermint leaves to rouse taste buds. The Bossa Nova oolong tea and China gunpowder green tea each contain hints of nutty aromas punctuated by a lingering sweetness, and the SPF-30 coconut-crème white tea balances a velvety texture and light body with a hint of the tropics.

After ordering a preconcocted beverage (not included with this deal), sippers can surf free WiFi from one of the lounge’s cushy black chairs, tune into an open-mic night held every other Thursday, or enroll in the café’s free Tea 101 class to learn how to decipher lost pin numbers by reading tea leaves. Groupon customers also receive a 10% discount on tea accessories for at-home steeping.
