When I ordered beer from an online store, I thought a delivery to a parcel machine would be extremely convenient. But Latvia has a funny law! Opening the parcel machine box constitutes an alcohol purchase. Therefore the box only opens 10-20, when shops are allowed to sell alcohol. The delivery arrived 18.30 and I missed the 20.00 deadline. So I started Googling, what is the temperature at which beer freezes. Looks like it is about -2 C, and that night the temperature went down to -3. It was not enough to explode the bottles, but the internet tells me freezing damages the beer's flavour. Oh well, you live and learn! Anyway, this is still very nice! Grainy and crisp. There's quite a strong grassy or vegetal flavour. I find this very satisfying.
