what is the difference between 6 quart and 8 quart instant pot?
The 6-quart Instant Pot is the most popular option—many recipes call for a 6-quart Instant Pot, and a meal cooked in the 6-quart variety feeds 3–6 people. The 8-quart, on the other hand, is ideal when you're feeding a large family, cooking for a party or doing weekly meal prep.
