Vitamix Ascent 48-oz containers are finally available in the US and Canada. Mine haven’t arrived yet, but, from the pictures, they look very similar to the Legacy 48-oz containers. The differences are that they have an NFC chip that activates the Ascent Self-Detect system, and they have clear snap-on lids.
Unlike the small 8-oz and 20-oz containers, the 48-oz container allows you to use a tamper. That means you can use it to make thick blends like frozen desserts, and nut butters. The advantage over the 64-oz container is that the 48-oz container is narrower, which means that you can make smaller amounts more easily.
The 48-oz container has 3” diameter blades*, whereas the wide 64-oz container has 4” blades. The minimum amount to blend is about 40% less. (The exact minimum depends on what you are blending.)
In my experience with the Legacy Containers, the 3” blades also lead to less splashing of small amounts of thinner blends. Splashing around inside the container isn’t a big deal, but given the choice, it’s preferable to avoid it. If you are trying to get every last bit out of the container, less splashing means you don’t have to scrape off the inside of the lid and the upper walls of the container.
There are trade-offs between using the wide container and the narrow container. I covered the advantages of the narrow containers above (blend smaller amounts and less splashing). The advantages of the wide container are larger capacity, less need for tamper in smoothies, and better chopping performance. If you can swing it, it’s nice to have both sizes available.
Vitamix Ascent Dry Container
Vitamix is also releasing a dry-blade container for Ascent. The dry blade is a different shape, and it is optimized for grinding flours. You can grind flour with the wet blade, but it doesn’t work quite as well. Also, it’s nice to have a dedicated container for dry ingredients, because dry ingredients scratch up the container much more than typical wet blending. Here are top-views of the blades:
Vitamix Ascent 32-oz Containers?
As far as I know, Vitamix does not plan on releasing a 32-oz container for Ascent. I presume that’s because there’s a lot of overlap between the Legacy 32-oz and Legacy 48-oz containers, given that they have the same size blade.
*Vitamix.com lists the Ascent 48-oz blade diameter at 2.8″, while they list the Legacy 48-oz blade diameter at 3″. I’ll investigate when it arrives to see if there is actually a difference.↑
