Minimum Combined Quantity for a Category
Requires customers to buy a minimum number of items from a category in total, for example any 6 wines, mixed as they like.

Code
$wpide_cat_min = array(
'categories' => array( 'wine' ), // Category slugs.
'minimum' => 6, // Minimum items from these categories.
'name' => 'wines', // Used in the message.
);
add_action( 'woocommerce_check_cart_items', function () use ( $wpide_cat_min ) {
$count = 0;
foreach ( WC()->cart->get_cart() as $item ) {
if ( has_term( $wpide_cat_min['categories'], 'product_cat', $item['product_id'] ) ) {
$count += (int) $item['quantity'];
}
}
if ( $count > 0 && $count < $wpide_cat_min['minimum'] ) {
wc_add_notice( sprintf( 'Please add at least %1$d %2$s to your order (you have %3$d). Mix and match as you like.', $wpide_cat_min['minimum'], esc_html( $wpide_cat_min['name'] ), $count ), 'error' );
}
} );Notes
Only carts that contain the category are checked, so other products can still be bought on their own.
