To create the Roasted Oolong Tea Lambiek – Sparkling Infused, one-year-old Lambic was infused with roasted Oolong tea for about four weeks. This tea, especially popular in Asia, is slightly oxidised and was then roasted in the traditional way. This results in a rich flavour, with a certain spiciness and some toasted notes. Thanks to the re-fermentation in the bottle, these flavours blend into one harmonious whole.
