Ask most people what New Year's Eve looks like for a small farmstead cheesemaker and they'll picture something quiet — the shop closed, the cave resting, a glass raised somewhere warm. One member we spoke with this week set us straight. "Cows don't know what day it is," she told us. "If they're in milk, I'm making. December 31 is a Wednesday to them." She runs a small mixed-herd operation in the northern Plains, and this year her last make of 2025 fell on the last day of the year, same as it has most years she's been in business.
What's different this week is the weather. A polar vortex disruption has been pushing arctic air deep into the northern Plains and Canadian prairies, with parts of the region running fifteen to twenty degrees colder than normal for the stretch — the kind of cold snap that turns a routine make day into a series of small decisions about heat, humidity, and how long a truck can sit outside before the milk inside starts to suffer. She's been running space heaters in the milk room overnight, something she says she hasn't needed to do this early in a winter in years, and keeping a closer eye on her cave's humidity than usual because cold, dry outside air has a way of pulling moisture out of a cave faster than the equipment can replace it.
What actually changes on a cold make day
The milk itself doesn't change much — her herd is barned and fed consistently regardless of the weather outside — but everything downstream of the vat gets harder. Rennet works a little slower in a cold room even with the vat itself held at temperature, so she's learned to budget an extra ten or fifteen minutes into a set she's timed the same way for years. Her draining room, usually the easiest space in the building to keep steady, has needed a portable heater running most of the week just to hold above the range where whey drains at the rate her recipe assumes. None of it is dramatic. All of it adds up to a make day that takes longer and asks for more attention than the calendar would suggest.
She's not alone in watching the forecast closer than usual this week — we've heard from a couple of other members in the same stretch of the country doing the same math on their own caves, moving wheels away from exterior walls and checking that backup heat sources actually work before they're needed at two in the morning. If your cave has never needed supplemental heat before, this is a reasonable week to find out whether it will, before a genuine emergency makes the question urgent.
Starting the new year the way she means to go on
Her plan for January 1 is unglamorous: sleep in an hour later than usual, then check the cave before she checks anything else. "The wheels I made today are the first ones on my shelf in 2026," she said. "I'd rather know how they're doing than not know." If you're facing a similar cold snap and haven't reviewed your cave's backup heating plan, our Milk Quality & Herd Health course touches on cold-weather handling, and the Food Safety Committee has fielded a few member questions this month about cold-weather milk transport that are worth a read before your next delivery.
