I usually keep Unsweetened Vanilla Almond Milk and I think it’s Lactaid brand lactose free milk in the fridge. I’m very tolerant of lactose and have consumed large amounts of milk all of my life but I do like the lower calorie nature of the almond milk and it tastes good to me when I use it in various things. Both have really good shelf life and that makes my shopping easier as I can buy a couple gallons of both and know that they’ll be good for a long time if unopened, though they do well once opened too.
The lactose free milk I keep for cooking (works great) and for a coffee drink now and again. I think Fairlife tastes good but it seems the Lactaid brand steams a bit better to me? I didn’t do extensive trials, but I think there’s a difference. Neither is quite as good a “real” milk in coffee but they’re a lot more convenient and good enough.
