To drain the bag, rather than a colander, I suggest you look at a vegetable basket for a bbq grill. They are cheap and mush sturdier than a colander. I also don’t use a hoist, just lift with both hands for 10 seconds until it loses some of the water and gets lighter, than hold with one hand while I use the other to insert this basket on top, then set the bag on the basket. I also use a silicone oven mitt to press the bag down into the basket to drain, flip it over and do it again. I used to then set the bag in a bucket to further drain during the beginning of the boil to recover more wort but this only got an extra cup or so, so I don’t bother with this anymore.
