I’ve recently received a bottle of gira (i.e. kvass from Lithuania).
With it came a beer mug, so I guess the issue of the glassware is settled. At what temperature should I drink it? If I understand correctly (which I probably don’t, given that everything is written in Lithuanian), the kvass is unfiltered. Should I pour carefully to avoid mixing too much yeast in the glass or, on the contrary, should I ensure that some yeast do go into the glass? Or is it purely a matter of taste?
Finally, at which temperature should it be served?
