There are many reasons to unplug the bombilla from the mate, either partially or fully. The server needs to constantly maintain space around the bombilla, while preserving the precious mountain of mate. At times, it’ll be necessary to totally remove the bombilla after taking a few hard slurps, then replace it in an superior position.
Unplugging the bombilla is good for removing cold pockets that had formed in your gourd, allowing you to achieve maximum heat retention with each fresh cycle. However, be careful, because this cycle will tend to be relatively hotter—make sure to warn the Materos, if necessary.
If the bombilla becomes clogged, one of the best ways to correct the issue is to unplug (running hot water through the bombilla if necessary) and reinsert.
